Hi there. As other posters have already told you there is no beach on Caulker. Before you go please search the web so you can see what you are getting into. There are beaches in Placencia and i loved the beaches in Hopkins, But please realize there will be sea grass and sometimes the beaches are very dirty. (i think from cruise ships dumping garbage)
Enjoy your trip to Belize and you will love Caulker, so laid back and relaxing, Three days is enough to stay there than go traveling and see the rest of the beautiful country. Whale Sharks will be in Placencia I think for the next month or two. I saw and swam with one last year. Awesome! I will help you out with any questions if i can. Email me
