One of the most beautiful tours in the Dominican Republic is the visit to the sanctuary of Humpback Whales in Samana. Samana's whales are well known. Each year 3 to 5 thousand humpback whales return to Bahia de Samana and the surrounding waters to give birth and mate for the following year. From January until March, you can see frolicsome males vying for the attention of the demure females.
