My husband and I have been going to Portsmouth, Dominica for the past 6 years. One of the things we love to do while we are there is to go diving. Fabian of "Island Dive Operations" (IDO) does a fantastic job. He is willing to take small groups which makes it so much more personal and much more enjoyable. He is located right next to the Blue Bay Restaurant on the beach in the village of Lagon. He is very professional and the diving is fantastic. Well worth it!!
