During the seasons when the sea is calm, the east and west coast of the island gets litter with pods of Dolphins. Though some say they can be seen throughout the year you can only go out to sea during the times when the seas in calm. The west coast is good during the end of the year and the east coast during the period between March and November. The peninsula or Kalpitiya along the north west cost is known as a hot spot for dolphin safaris. Over a dozen species of Dolphins can be seen off the islands coast which include the acrobatic spinner and bottle nose dolphins, large pilot whales and rare orca or killer whale.
