Moncho's Rentals is where I rented my golf cart for $32.00US per day.
I stayed at Mata Rocks and walked the beach front most of my stay. If you have no injuries walking everywhere is easy and safe. From Mata to downtown was a 30 minute beach walk. Again I traveled alone and never felt unsafe. It is impossible to get lost since there are only three streets. I went to the clubs on two nights and took a taxi one night (too many Mojitos) the cost was $5.00US.
I always fly American as they usually have the cheapest prices.
Another possibility is flying into Cancun and then taking the bus the rest of the way down. Can save you mega bucks sometimes. Batty Brothers also has a bus service all the way from Los Angeles to Belize-wow can't imagine that trip.
Take the airplane from the airport to the island unless you don't mind getting wet and having a bumpy ride.
Seriously, if it is a beautiful day and you are an adventrous person take the water taxi. It is a good way to see the island. But you will get wet and it can be a bumpy hour.
If you are staying directly in town then your own 2 feet are the best mode of transposrtation. If you are staying south of town-get a golf cart or rent a bike.
Definitly rent a golf cart at least one day and ride it to the north side of the island-a completely different atmosphere.
the means of transport on the island are electrical cars like this but I felt like the tourist of a movie, the only place where I had seen these sort of cars till then, to rent one... anyway I got on one: the taxi I took from the airport when I hadn't realized yet ;-) you can easily reach any point on the island on foot...
What an amazing introduction to Caye Caulker. First getting off a small plane to a small airstrip area to hop on a GOLF CART taxi. Yup, the taxis on this island are stretch golf carts. There were not too many golf carts on the dirt roads, but they were practical for carrying around a lot of stuff. I did not see any street signs, nor traffic signs, except for the occasional "Go Slow" signs.
Getting around Caye Caulker is easy. The sand is white so you can walk bare foot, which is nice because it's so warm.
Rent a bike if you want to get around faster, or hire a golf cart if you can't walk.
I know of no one who's gone there except via commercial air.
At least once, try the boat ride from Belize city to Ambergris Caye.
Normally, use the island airline to Ambergris Caye
Rent a golf cart, it will be the best money you'll spend on the island.
We drove all over the caye in our little golf cart.
I don't think it was built to carry such a load.
It was fun but not much protection from the rain.
Most Transportation around town is by foot, bicycle, or golf cart. there are a few van style taxis roaming the streets and don't be surprised if a golf cart driver offers you a lift to town .
