Visited this site in May 2018. There was still very dirty road from Baracoa, which took us over 1 hour to cover 30 km.  Parque Nacional Alejandro de Humboldt, covering 707 square km, is famous for its richest fauna in the Caribbean with many endemic wildlife species. The visitor center is located directly on the main road, with some basic information, bust of Humboldt and excellent view over the moon-shaped lagoon. There are 1,200 different species of animals and 1,000 species of plants in the park, 70-80% of them are endemic.

At the time of research, there were three available guided trails, except longest 3.5-day trail and Bahia de Taco trail due to the absence of boats to cross the river. We paid 10 CUCs for two of us and decided to do a boat trip around lagoon with the guide Junior. The boat was completely hand pulled by Junior, as they do not use engines in order to minimize damage to the park. We did a circle around lagoon, visiting mangrove forest, a number of hummingbird nests and enjoying beautiful views back to the shores. This was a very pleasant boat trip followed by a lunch in the family suggested by the guide. The further 20-km stretch of the road to Moa is still dirt and improves around dirt nickel plant only.
