The Dominican Republic is one of the most biologically diverse regions in the Caribbean, with more than 6,000 plant species, over 300 bird species, about 30 endemic species, and more than 800 marine species. From the mangroves of Los Haitises to the forests of the Cordillera Central, from the saltwater lagoons of the wild Southwest to the coral reefs of Monte Cristi, the country is a true natural sanctuary.

January through March: Humpback Whale Season
Between mid-January and late March, Samaná Bay welcomes approximately 1,500 humpback whales that have traveled from the cold waters of the North Atlantic to breed and give birth. Samaná Bay is a deep, sheltered bay rich in nutrients and has been designated an official marine mammal sanctuary since 1986.
It’s the best wildlife experience in the Caribbean. Set out from the Samaná Peninsula to witness this unique spectacle. The beaches of the Samaná Peninsula and the villages of Las Galeras perfectly complement this nature-focused getaway.
Birdwatching: A Paradise for Birdwatchers
The Dominican Republic is home to 32 endemic bird species and more than 300 recorded species. Thanks to its geographic diversity (ocean, mangroves, mountains, dry savanna), birdwatching is possible year-round. The premier birding destination in the Dominican Republic: the Sierra de Bahoruco, a UNESCO Biosphere Reserve.
Endemic and Iconic Species
- Rhinoceros iguana (Cyclura cornuta) – Lake Enriquillo
- Ricord’s iguana (Cyclura ricordi) – a rare species
- Paradoxical solenodon – rare prehistoric mammal
- Hutia – endemic rodent
- American crocodile – Lake Enriquillo
Manatees and marine life
On the north coast, near Punta Rucia (Estero Hondo), lives one of the largest manatee colonies in the Caribbean. The Dominican Republic is also home to bottlenose dolphins, leatherback, hawksbill, and green sea turtles, coral reefs (Monte Cristi, Bayahibe), and more than 800 species of fish.
Marine Life and Diving
Dominican waters feature coral reefs spanning over 200 km². The main diving and snorkeling areas are located in Bayahibe, Monte Cristi, and Punta Cana. The dry season (December through April) generally offers the best underwater visibility. Biodiverse mangrove forests, such as those in Los Haitises National Park, are also not to be missed.
