We have visited Grenada many times in the last 12 years and love it for its people, mountains, rainforest, hiking, fresh fruits and veggies and quiet beaches. We are also avid snorkelers but you need to know that while you can find adequate snorkeling it is not as good as some other islands. Because of the rainforest there is quite a bit of runoff so some spots are not as clear; the fish are not as abundant as on some islands but to us every day of snorkeling is a worthwhile day and we always see interesting things in Grenada. We always rent a place with a kitchen (grocery stores, fruit stands and fish markets are all good) and some of our favorites are Grand View Inn, Flamboyant, Twelve Degrees North, Lance aux Epines Cottages and a house that we once rented, Fiddler's Reef. The first two are overlooking Grand Anse Beach and are situated on a hillside -- some people do not like the walk back up after time at the beach. The last three are in the quiet area known as Lance aux Epines and each has a small beach. At Fiddler's Reef the owners will take you out to a reef in their dinghy. You can snorkel from shore at the beach at the Aquarium restaurant and the beach at the Beach House Restaurant. A day trip on Starwind is a great way to sail and snorkel and a ferry ride to Carriacou and then a water taxi to Sandy Island is also a fun way to snorkel. Good luck! Grenada is our favorite of the many islands we have visited!
