The park is a protected area of the biggest biodiversity of Cuba and of any island of Caribbean. It is located in the provinces of the Oriente of Cuba: Holguín and Guantánamo. It is a great park about 70000 hectares.
The area constitutes one of the most valuable places for the conservation of the endemic flora in the whole Western Hemisphere. For this reason it was inscribed as a UNESCO World Heritage Site in 2001.
Fauna present in the park includes various species of parrots, lizards, hummingbirds, the endangered Cuban Solenodon (endemic), Hutia and snails.
To get to the park entrance is to go from the south Baracoa toward Moa. The road is mostly rough so it gets about 1 hour to drive there. And it's the best way to there by car as theere is almost no traffic there except tourist cars which are rare too.
The park is named after the German scientist Alexander von Humboldt who visited the island in 1800 and 1801.
