The tours aren't very long, it is a small Island and they will show you the main sights, Cptn Morgan's cave, The blow hole, The natural Pool, The view from the Highest point on the Island, and generally tours of Colonial houses. It's a good way to get a feel for the place, see beautiful sights and at some of the stops they might have local music or dancers.
Not to be confused with the Decameron Aquarium, The Aquarium Cay is a little Island off San Andres that attrackts a huge variaty of fish. This is the easiest snorkeling and fish watching I've ever done. Even if you don't snorkel, hell, even if you don't swim, you can wade out into the water, use swimming goggles and see an amazing variaty of fish. This one is worth scrolling through all 5 of my pictures.
The area known as the Natural pool has water so clear that you can look fown from the cliffs above and clearly see fish swiming under 10 FT of water. If you go bring your bathing suit. You can jupm in from about 10 or 15 feet up and see a ton of fish attrackted by bread crumbs convieniently made avalible on the path to the cliffs.
Jonney Cay has berhaps the most perfect beaches I've been to. The Sand is soft, White Coral sand that doesn't heat up in the sun. There are palm treas just off the beach for shade and Coconut drinks and grilled food avalible from shacks on the Island. Just out to sea the beach turns into interesting rock and coral formations that hide very cool fish. not the best snorkeling in the area but a fun place to be.
While the Aquarium might be the bedst Decameron Hotel, the Isleno has the best beach. Luckly, if you stay at one you are welcome at them all and anyway the beach in front is public. It has the nice long cresent shape and soft white coral sand that doesn't heat up like other sand. Dead center in front of the Beach is Jonney Cay, looking like such a tropical paradice that you almost forget that you already are on a tropical paradise. Half the beach receives shade from tall palm treas and occasionally a man will come by balancing a plate of Cocada on his head. Dont miss these delicious Coconut treats.
Simply amazing, probably the best beach on the entire island! It's a short boat ride past the barrier reef, then a short ride you arrive. I spent the whole day there, relaxing and enjoying the beach. There's not much to really see there, but in comparison to San Andres, it's a great contrast!
