We met a business associate who happens to own a home about 1 half hour away that he spends Feb there each year who we walked all around old Jan Juan. Very peaceful and beautiful reminded us of some small European towns .
Do not hesitate to take the Americas Cup Regatta . As long as you are reasonably fit you will love this as you compete against two other sailboats and if you wish become part of the crew actually working to bring your team to victory. It was so much fun and for real not staged. After the racs the nearby beach is also very nice.
Great boat ride out to a couple of areas both different one where sea turtles hang out and some fish the other a barge that was sunk and is now starting to grow coral and then near the island some nice easy snorkling with a nice array of fish.
