Try cholo's we where there in Oct. and had a great time snorkeling and fishing with one of their guides I am pretty sure they have a web site, but if you can't find one, they are located on front street by the green house, and the Belize bank, right on the beach. If you ask around where you are staying any local will know where it is located, they also have a bar by the same name right there on the beach in front of their dock. The prices where very reasonable, and if you catch some fish, if you want, your guide will cook them up for you on the beach they did a great job with the cooking I must add. Hope you have a great time and catch a lot of fish. Good Luck
