Alejandro de Humboldt National Park

Alejandro de Humboldt National Park covers about 710 square kilometres of the Sagua-Baracoa mountains in the far east of Cuba, shared between the provinces of Guantánamo and Holguín. It climbs from a coast of mangroves, bays and coral to peaks of roughly 1,170 metres, with lowland rainforest, pine woods and cloud forest in between.

The unusual part is the rock. Much of the park sits on serpentine and peridotite, rock pushed up from the Earth's mantle that is short of nutrients and toxic to most plants. The few that coped adapted, and then split into new species. Cuba's nomination file counts 905 endemic plant species here (species found only in Cuba), and 343 of those grow nowhere outside the park. It rains a lot, and the whole arrangement depends on it.

People are part of the picture, in small numbers. The IUCN counts 11 settlements with about 5,450 residents inside the boundary, and the coastal valleys were planted with coconut and cacao through most of the last century. Visits are usually arranged from Baracoa, the old coastal town on the Atlantic side, where the road from the mountains meets the sea.

The story starts underground. The park lies on an island-arc structure built up between the Oligocene and the Quaternary, with a base of ocean crust (ophiolite, in the geologists' word) that was thrust up from the Earth's mantle at a subduction zone. Parts of the serpentine and peridotite massifs have stood exposed for more than 40 million years, which makes them among the oldest in the Caribbean, according to Cuba's nomination file. The same rocks are rich in nickel, a detail that matters later in this story.

Over that time the land was planed and weathered into long, high plateaus, with thick crusts of weathered rock on top. One block did something odd. The limestone mass of the Farallones de Moa sits like an island among the serpentines, and its Great Cavern is one of five natural sites in Cuba officially regarded as national monuments. Elsewhere the park has what is called pseudokarst: sinkholes, closed basins and caves, normally a limestone habit, formed in rock that isn't limestone.

The region also had good luck. The nomination file says the climate here was little disturbed by the glaciations of the Quaternary, so the mountains served as a refuge for Caribbean plants and animals, and the Committee's inscription text puts that refuge role in the Miocene to Pleistocene. Add the toxic soils and the huge swings in rainfall, and the result is a slow machine for making new species. Parts of the park have never had a plant collected from them, the nomination file admits, so the species lists are still incomplete.

People left a light mark. Only one pre-Columbian archaeological site is known, at Aguas Verdes on the coast. In the 18th and 19th centuries some peripheral places in the mountains were used as palenques, shelter sites of people who had escaped slavery. In the early and middle 20th century the coastal valleys were planted with coconut and cacao, and around La Melba underground chromium mining created a small town. Farms on the Toa and Jaguaní riverbanks in the 1940s and 1950s were abandoned by the end of the decade because the access was poor and the crops weak. In the 1960s and 1970s the pine woods of Ojito de Agua were logged, until protection ended it in the mid-1980s.

Protection came in steps. The Jaguaní and Cupeyal del Norte natural reserves were set up in 1963, and the whole area became part of the Cuchillas del Toa Biosphere Reserve in 1987, a UNESCO designation whose core area was recorded as 89,741 hectares, larger than the park that later grew inside it. In 1986 Cuban biologists Giraldo Alayón and Alberto Estrada reported ivory-billed woodpeckers at Ojito de Agua, and the woodpecker specialists Lester Short and Jennifer Horne confirmed the sighting weeks later, according to Audubon magazine. Ornithologist Martjan Lammertink then spent eight months at the site across 1991 and 1993 and found no sign of the birds. In 1996 the reserves were united as a single national park, named for the German naturalist Alexander von Humboldt.

The World Heritage Committee inscribed the park on 16 December 2001. At that point the nomination still described parts of the terrestrial and marine area as awaiting approval, and the Committee asked Cuba to finish its management plan within 12 months. A plan for 2009 to 2013 followed, and a later one for 2021 to 2025.

Trouble has come from outside the boundary as much as inside. Between 2000 and 2006 the state granted or confirmed eight nickel-mining concessions around the park, hurricanes such as Ike in 2008 and Matthew in 2016 flattened stretches of forest, and illegal gold mining has taken hold since 2013. Those threats are taken up under Challenges.

Start with the small things, because the park's records are mostly small. Cuba's nomination file says the park is home to three of the smallest vertebrate species in the world, and the UNEP-WCMC datasheet names them: a bat of two or three grams, the bee hummingbird at 63 millimetres and a frog of 11 millimetres. Add the Cuban solenodon, a shrew-like mammal the datasheet calls a living fossil, and the painted snails of the genus Polymita. A walk here is a good way to find out how many forms nature can fit into one mountain range.

The place also explains itself as a walker climbs. From mangrove and coastal scrub, the forest steps up through lowland rainforest at 200 to 400 metres, submontane forest to about 600 metres, montane forest above that, and cloud forest above 1,000 metres. There are pine woods in places, and on the serpentine a thorny scrub in which about 80 per cent of the species are endemic. Altitude, rock and rainfall are all written into the vegetation, and they change within a few kilometres.

Then there is what the park says about how nature copes. Plants adapted to poisonous ground, and animals sheltered through the ice ages while the climate stayed comparatively steady here. Cuba's own file calls it the largest block of preserved mountain ecosystems in the country, and the UNEP-WCMC datasheet adds that it is still among the least explored, with places where nobody has ever collected specimens.

A caution belongs here as well. Much of this is not visible from a trail. Most visitors will see a bay, a river valley, a waterfall and a few birds, which is plenty, but a good part of the park is hard to reach and not open to casual visits. It rewards patience and a good guide more than it rewards a checklist.

The park lies in the Sagua-Baracoa mountains, at the eastern end of Cuba. According to the UNEP-WCMC datasheet the site stretches for about 50 kilometres from the mountains to the sea, and it is roughly 30 kilometres north-east of the city of Guantánamo. The land runs from El Toldo peak, at around 1,170 metres, down to the shore, and the landscape takes in tablelands, coastal plains, bays and coral reefs.

The datasheet describes a hot subtropical climate. Most rain falls from May to October, hurricanes are a risk between August and October, and humidity runs between 75 and 95 per cent. The cooler, drier months are January to April, with temperatures between about 15 and 32°C. Rivers such as the Toa-Jaguaní, Duaba, Jiguaní, Nibujón and Moa run clear off the hills, helped by the forest cover.

The layout is looser than the map suggests. The nomination file describes two main sectors, Cupeyal del Norte with Ojito de Agua in the north and Jaguaní, plus a coastal and marine strip, with a buffer zone (the surrounding land that has extra controls to protect the park) of 34,330 hectares. A coastal road crosses the lowest part of the park, and most farming sits in the valleys of the Santa María and Nibujón rivers.

On the western side lies Moa, a neighbor with a very different business: its nickel-mining zone lies downstream of the park. Baracoa sits at the other end. Park staff work from Guantánamo, with secondary offices at Piedra La Vela and Baracoa and posts at Taco, Cupeyal del Norte, La Melba and the Farallones de Moa.

Take a rain jacket, even in the dry months. The climate is hot and humid year round, with humidity between 75 and 95 per cent according to the UNEP-WCMC datasheet, and the hills collect their own weather. On a gray afternoon the forest drips and the trails turn into something between mud and slide. That's the price of a forest that still exists, and most people stop minding after the first waterfall.

These are walks rather than expeditions, but they're not flat. The Balcón de Iberia route runs roughly 5 kilometres, with a climb through farmland and a descent through rainforest, and the rocks near the water are slick. Wear shoes with grip, carry plenty of water and food, and bring a swimsuit if you fancy a plunge below the falls. A Baracoa operator also advises a light rain jacket and a tip for your guide.

You probably won't be crowded. The nomination file and the UNEP-WCMC datasheet both said that almost all visitors were local people or researchers. Those were reports from 2001 and 2012, so treat them as the mood of the place rather than today's numbers. On some paths local women sell coconut sweets, a decent excuse to stop.

The boat trip around Taco Bay is slow, with a staff member rowing. You can see waterbirds, and now and then a manatee turns up beside the boat. Nobody can promise it, but it's worth asking the rower where to look.

The roads to some trailheads are rough, and the tourist board describes the Yateras approach as mountain road with irregular relief. In the back-country, sand flies, mosquitoes and untreated water are a risk, which is another reason to go with people who know the ground. And power, fuel and water shortages across Cuba may affect transport and what is on sale locally, so carry more than you think you need.

Start with the official advice. At the time of writing the UK Foreign, Commonwealth and Development Office advises against all but essential travel to Cuba, citing fuel shortages, repeated national power grid failures, disruption to transport and flights, and problems with international bank cards. Other governments publish their own advice, and a traveler should read it before booking anything.

If you do go, a full day is the minimum for the main trails and the bay, and Baracoa is the usual base. The drier months are January to April, according to the UNEP-WCMC datasheet, while most rain falls from May to October and hurricanes can arrive between August and October. Hurricane Oscar made landfall in Guantánamo province on 20 October 2024 and brought unprecedented flooding to Baracoa, so the end of the year can still be unsettled.

Operators in Baracoa describe guided visits as the normal way to see the park, with local guides who know the plants, animals and traditional medicine. We could not confirm current ticket prices, opening hours or whether guides are compulsory, so ask the park or a Baracoa operator before you travel. The remote Ojito de Agua sector needed official clearance in Guantánamo in 2016.

Take cash, since the FCDO says international cards are not being accepted and that US dollars and euros are widely taken. Keep plans loose, build in a spare day for weather, and expect services to change at short notice.

The park has no single entrance. Cuba's tourist board says it is accessible both through Baracoa and through the mountain town of Yateras, and the western end near Moa, on the Holguín side, is a third approach, though one 2016 expedition was turned away there. For most visitors Baracoa, at the eastern end of the Baracoa to Moa coast road, is the practical starting point.

The province has two airports. Mariana Grajales serves Guantánamo, and Gustavo Rizo serves Baracoa, on the Jaitecico highway about 1.5 kilometres out of town. The FCDO reports that Cuban authorities say all international airports lack aviation fuel and that several airlines have suspended flights, so check what is actually flying before planning around either.

By road, Baracoa is reached from Guantánamo by the central highway and then the Farola viaduct road over the mountains, according to Cuba's tourist board. The national long-distance bus company has stations at Guantánamo, on the central highway at kilometre 2.5, and at Baracoa, near Martí Street and the Malecón. Rental cars are listed at both towns. Journey times and typical fares for each leg could not be confirmed at the time of writing.

Once in Baracoa, getting around means taxis, rented cars or motorbikes, or transfers arranged with a guide. The UNEP-WCMC datasheet places the park about 30 kilometres north-east of Guantánamo, and the coastal road runs through the park itself, with the tourist board listing a lodging called Humboldt Park at kilometre 40 of the Baracoa to Moa road. The Balcón de Iberia trail starts in the Santa María valley, and the Yateras approach ends at Piedra La Vela, up a mountain road.

For visa and entry rules, use your own government's travel advice and the Cuban authorities' consular pages, since they depend on nationality. The UK government's entry requirements page for Cuba is linked from its travel advice.

Mind the weather. Hurricane season runs from August to October, and Oscar brought flooding to Baracoa in October 2024. Fuel shortages across the country can disrupt buses, taxis and the petrol supply for rental cars, so leave slack in the schedule.

Around 5,450 people live in 11 settlements inside the park, according to the IUCN's 2025 assessment. The largest was La Melba, which grew up around chromium mining and had about 400 residents in 2000, with another 4,000 or so estimated in the buffer zone at the time. Farming is concentrated in the coastal valleys of the Santa María and Nibujón rivers.

The cultural pull is Baracoa, a town founded in 1511 and presented by Cuba's tourist board as the capital of coconut, with the nearby community of Mabujabo billed as the capital of cacao. The board's guide says that in Baracoa 'the coconut is broken with the head', and it describes traditions around the cucurucho, a sweet made from grated coconut. Rural traditions have their own music: Nengón and Kiribá, rhythms of the country life of the Baracoa area, are celebrated at a festival named after them.

History runs through the mountains too. In the 18th and 19th centuries, people who had escaped slavery sheltered on the park's edges, and the memory of those palenques is part of the area's story, though the sources we found say little about what remains.

A word on what we do not know. We did not find reliable published accounts of how local communities themselves describe their relationship with the park, apart from the observation that coastal households farm coconut and cacao and that guides are drawn from nearby villages. A visitor who meets them can simply ask. The best conversations here tend to be with the people who work the land: a guide, a farmer, a woman with a basket of sweets on a trail.

Carnival in April adds a splash of color to Baracoa's year, and the town's Fiesta de las Aguas in August marks the anniversary of its foundation.

The park is named after Alexander von Humboldt, but the places recorded for his visits to Cuba don't include these mountains. According to CubaPLUS Magazine, he stayed on the island from 19 December 1800 to 15 March 1801 and again from 14 March to 29 April 1804, and the places it names are Havana, Guanabacoa, the Güines plain, Batabanó and Trinidad. The UNEP-WCMC datasheet says he became known as the second discoverer of Cuba. His book on the island appeared in Paris in 1826, and the colonial authorities banned its distribution. The first Cuban printing came in 1930.

Then there is the woodpecker. Audubon magazine told how, in 2016, Tim Gallagher and Martjan Lammertink led a search for the ivory-billed woodpecker at Ojito de Agua. The government jeep stuck in the mud and was pulled free with oxen, the party spent a night at a military outpost, and the double-knock calls and a 1935 recording of the bird drew no reply. They concluded that the species is probably extinct in Cuba.

A smaller story concerns scale. The datasheet lists the Monte Iberia frog at under 11 millimetres and the bee hummingbird at 63 millimetres, and says both live in the park, along with a bat weighing two or three grams. Cuba's nomination file calls them records for the smallest of their kind. Few visitors will spot any of the three, and that is half the charm.

Last, a story from just outside the boundary. Cuba's tourist board quotes Christopher Columbus's diary describing 'a high, square mountain', which it identifies as El Yunque, the flat-topped peak beside Baracoa. It also records the Parra Cross, said to have been placed in the port of Baracoa in 1492.

Baracoa is known in Cuba for two crops, coconut and cacao, and most of what is distinctive to eat comes from them. The best place to start is the cucurucho, a sweet of grated coconut that Baracoa operators describe being sold on the trails near the park. Turrones, the nougat-style sweets the tourist board mentions alongside it, and coconut brittle sit nearby. A cold coconut water is a favorite after a muddy walk, and the board also lists coconut oil among the local products.

Cacao is the other half. The tourist board lists a cocoa and chocolate trail in the Baracoa area, where a guide explains the process in the plantations and visitors taste Creole chocolate at a farm. Mabujabo, a few kilometres out on the Moa road, is promoted as Cuba's capital of cacao.

Most visitors eat in town, and the stalls near trailheads are the place for something to carry. We did not find reliable current information on specific savoury dishes tied to the park itself, so the best advice is to ask at a guesthouse what is in season. Supplies can be uneven at present, so bring snacks.

The park sits in the far east of Cuba and runs along the coast, with Baracoa at one end and Moa at the other. Baracoa, which Cuba's tourist board calls the first city of Cuba, founded in 1511, is the practical base: it has the airport, a bus station, rental cars, places to stay and the operators who run park trips. Its small centre also has a fort museum and a cathedral.

To the west, Moa is a mining town, with a nickel-mining zone downstream of the park. Guantánamo, the provincial capital, lies to the south-west and is where the park's main administration is based. Yateras is the mountain municipality used for the south-western approach. Sagua de Tánamo, in Holguín province, is the other municipality that shares the park's land.

The surrounding Cuchillas del Toa Biosphere Reserve covers the park and more, including El Yunque, the flat-topped hill beside Baracoa, which stands at 576 metres. Beaches such as Maguana and Mapurisí lie along the coast near Baracoa, and the Toa is described as the mightiest river in Cuba. Ask a driver or guide for distances from Baracoa along the Moa road; the lodging listed at kilometre 40 is a useful marker.
