Where is the best place to stay in Grand Cayman with diving in mind? I'm in the process of looking at hotels and what to be close to dive shops.
What are the best dive locations? I particularly like swim throughs, kinda like the Palancar Caves in Cozumel.
"Best place" is very subjective without any type of parameters to define "best". Therefore, I'll answer your other question.
The east of the island has some great swim-throughs. Some examples are The Maze, Iron Shore Gardens, Snapper Hole, and there are many more. Ocean Frontiers / Compass Point is a nice resort on the East End. The owners run a very nice operation; I used to work for them when I lived no GCM.
On the east end there are not as many operators which means diving on a divesite with a swim through is very likely. On the west end, there are many dive operators which means you may not get a divesite with a swim through because someone got there first. .
Also, the rum cakes on Cayman are really good. Good luck and have fun.
