By taxi
Once on the Island, there are not many ways to get around besides private car. There is no public transportation. Depending on which hotel you stay at, they may offer transportation services. If you are not staying at a hotel and need to get around, you can use a taxi service. The Island is very strict with drunk driving, so when you go out at night, make sure you have a ride back to where ever you are staying. Remember, it is better to be safe than sorry.
