There's a little Island about 15k sq ft big (maybe bigger) just south
east of Bahia Honda State park around mile marker 30 of the Florida
Keys. The spot is a little touristy, as you might have to share it
with a person or two on a the weekend. However, I think it's a very
nice Atlantic kayak paddle and a great midway point to beach the Kayak
and snorkel around the island as it has an abundance of reef and wild
life - with thousands of live Conch shells (don't touch them please
it's illegal). I really like that spot - A great first adventure if
you ask me.

When I first read this, I missed the "k" part of the 15k sq ft. :-) A 15
sq. ft. island in the Keys sounds like paradise!!!!
