There is a small pod of dolphins in Eilat, Israel, living in a meshed-in area close to the shore. You can pay £40 and a scuba instructor will take you underwater with them.

As well as Kaikoura, there are commercial swim-with-dolphin ventures at Dingle in Ireland; Eilat in Israel; Bay of Islands, North Island, New Zealand; and Port Philip Bay and Monkey Mia, Australia.
Jean Sinclair

Although many people dream of swimming with wild dolphins, this has become, in all too many instances, a green light for commercial operators to make a lot of money from eager tourists, with scant regard for the stress and disturbance this often causes to the dolphins. The Whale and Dolphin Conservation Society has a policy on swimming with dolphins. Please see our website (www.wdcs.org) for more information.
