You can take a water taxi to Caye Caulker.
Coral Breeze seems to be a broker these days (a smaller version of shore trips). I would contact them about their shark ray alley expedition as an observer, skipping the shark ray alley and snorkel bit (unless you want to do that part). You could get up to 3 hours on Caye Caulker. But make sure they say it is ok.
