On Ambergris Caye, transportation primarily consists of golf carts, bicycles, and motorbikes. There are taxis and trucks if needed but most people walk or hitch a golf cart ride to get into town. This really adds to the friendly and social atmosphere that Belize and Ambergris Caye are known for.
Luckily, the island is extremely accessible for those that aren't interested in renting a car or golf cart. If you want to more exploring, flights from Belize City to Ambergris Caye are only 10-20 minutes in duration and boats or water ferries can get you from Ambergris Caye to the famous Hol Chan Marine Reserve or Caye Caulker relatively cheaply.
