With over 21 years of experience with the sperm whales in Dominica, this region is considered to be the very best place for up-close encounters with the largest toothed whales on earth! Dominica is home to over 200 resident sperm whales. The whales are in Dominica all year round, and Dominica has the most social groups, who are used to human presence, offering exceptional interactions. The blue waters are another draw for many, as it much easier to get fantastic footage and photos of these amazing whales.
