Extra nice is this scenic park just a few hundred yards down from famous Mallory Square. Boating is hugely popular from this location. Go in either direction to circle the entire island of Key West. A lot of people stop by and drop in the kayak. What a super place for some watersports.
Kayaks do have to be careful if you launch from here, there are some huge boats heading in and out of Bight Marina. There are a number of very good places to drop in a kayak around Key West. Pick a nice day with calm winds to really get into the watersports scene.
We like the carysfort Lighthouse reef area a lot. We like to stop on the way down to Key West and do a dive in Key Largo, out from card sound at a depth of three to seventy five feet. The landmark is the carysfort lighthouse mooring buoys. This is a skill level of beginner with a focus on snorkel and scuba.
