Best Snorkelling

Hi All I know there are countless posts out there regarding this but just wanted to see if there is any updated information. Im living on the island for 2 weeks and have a moped and just wanted to get recommendations for best places to go for snorkelling and what if any costs I may need to prepare myself for. Im not looking for a tour. I have my own gear. Any recommendations would be greatly appreciated. I hear money bar is the best for snorkelling from the beach and was just curious if there are any fees i would need to be prepared to pay
