This is a fantastic destination. It is only a 30 minute water taxi from Belize City. Caye (pronounced key) Caulker is small, but very relaxing. Go to the split and have a drink at Lazy Lizard’s, swim, or play volleyball in the water. We stayed at Popeye’s which is nice, affordable, and has one of the best managers I’ve seen, Manuel.
You must . . .
get a coconut cookie from Rasta Pasta
snorkel or scuba (preferable all day on the sailboat with Raggamuffin tours)
have a cuba libre (make sure it is with 1 barrel)
sit in the swings at the I & I bar
hang out and do nothing . . . you are probably on vacation!
