When staying on the Cayes, lots of the accommodations offer bikes. They are a great way to get around the relatively small islands. With the baskets on them, you can actually carry back quite a bit too, if you are going for supplies or shopping.
If you are getting something really big, you can also rent golf carts (the main means of transport on the islands). If you just want to zip around sight seeing, then a scooter is the way to go.
I managed to see most of Ambergris by riding a bike around for a couple hours. It was also a quick way of getting downtown when I needed to withdraw some cash to pay for wedding rehearsal dinner.
After some foot-slogging around town on our first partial day on Ambergris Cay, we decided that a bicycle would be the more sensible way to go! After all, it was at least an hour's walk from our hotel at the north end of San Pedro to the resorts at the southern end and that midday sun can be quite hot.
Many people rented golf carts (about US$50 for 8 hours), but I did not want to spend that much money and would rather get some exercise while touring around, so we opted for the US$7.50 per day bicycle rentals. Located on a busy street in the middle of San Pedro, Joe's Bike Rentals was just a small shop with plenty of bikes on hand. They come with a front basket to make it easier to carry your goods and also a keyed lock and chain to secure things when you want to enter a restaurant or whatever.
It was a bit strange at first riding an old-fashioned 1-speed bike with pedal brakes and no rear-view mirror, but it did not take long to get used to the change in technology! You had to keep your wits about you in the downtown streets (see my 'Warnings' tip) but overall, it was a very nice way to quietly and easily navigate around town! Highly recommended as a way to get around with a minimum of effort. We managed to get the bikes and ourselves back to Joe's undamaged before his 6 PM closing time.
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 walk.
A lot of the inns will provide bikes for tooling around Ambergris caye, you can also rent golf carts but they tend to be a little expensive if you are trveling on a more modest budget. I don't know if the larger hotels provide bikes, but it was a nice touch. The roads in San Pedro aren't paved so if you've had a few too many drinks with little umbrellas in them and fall off your bike, it wont hurt too badly!!!
Fly.. Definitely the best! American and Continentalairlines fly to Belize City viaTexas. Currently there are not any cruise ships going to Belize. But there is talk of future cruises to Placencia where the off shore waters are deep enough to allow larger ships to approach the main land,
Fly.. Definitely the best! Tropic Air and Maya Island Air fly between all the major cities for a relatively low cost. Higher than bus or water taxi, but less than car rental. The main highways are mainly dirt roads passing through agricultural centers where big trucks literally dust you off the road making traveling by highway uncomfortable. Save the road trip for excursions into the jungle or to tour the awesome ruins. The water taxis are inexpensive but slow going and often bumpy when the sea is choppy. Golf carts and bicycles are popular on the Cayes for getting around the smaller islands. Golf cart and bicycle rental services are available on Caye Cauker and in San Pedro Town on Ambergris Caye. Car rentals are available in Belize City for around $80 US/per day. Travel by plane will save you time and money.
