The cyclones in February and March, 2005 sadly devastated the fringing reef off Muri beach, but snorkellers can still have a great time just a few minutes up the coast from there opposite Fruits of Rarotonga. For the best experience, go down on to the beach, turn right and walk about 300 metres, then swim towards the edge of the reef (but NEVER over it)...it's perfectly safe and the fish are very friendly!
