A boat tour around the island of Bréhat is an excellent way to appreciate the variety of the jagged coasts, the beauty of the rocks and northern cliffs, the more Mediterranean charm of the eastern shore, the changing colour of the waters that sometimes veer towards a deep blue. It also gives you a better view of the birds, especially on the northern coastline where great black-backed gulls, cormorants, sandwich terns, Northern gannets and common ringed plover have set up home.
