The beaches are all kind of connected, so it's really like this one large beach with the buildings outlying the beach. I think it's pretty large (wouldn't say small). The hammocks are great! I think there are about 2 hammocks every 4 buildings or so. They are addicting. "Oh, I'll just sit on this hammock for a few minutes..." turns into whoa, 2 hrs have gone by? And in case you were wondering, swimming is not allowed in the beach "lake." I think you can put your feet in at least.
I'm not sure how Trinidad South's beach looks since t's kind of across this road/street and we never went over that way.
