I am travleing with 6 adults and 2 children what is the cheapest way to get from San Pedro (Banyan Bay to be exact) to Caye Caulker for an afternoon or a day.
On the Caye Caulker Water Taxi, unless you can find a charter boat in San Pedro to take you there and back for 200 bzd. Adult round trip tickets are 30 bzd ($15 U.S.) and children 4 years and older ride for 1/2 price.
You are right, I always forget about Triple J. Where does their boat leave from in San Pedro? I know they arrive at the Rainbow Restaurant dock here on Caye Caulker.
I think it was Triple J that I took once. Cheaper for sure but didn't run nearly as often as the water taxi. I think the pick up for this on was near the Amigo's Del Mar pier.
*disclosure: I used Triple J a bit over a year ago so they may have more boats running.
