Getting around any of the Virgin Islands is fairly easy. All of the islands have bus service and/or a regulated taxi service. Upon docking at Cruz Bay, taxis, rental cars, and scooters are available.
By Taxi And Bus
Upon landing at the Cyril E. King Airport on St. Thomas, one could rent a taxi or take buses to Charlotte Amalie, or to Red Hook, either of which have ferry service to Cruz Bay, St. John. You can "bargain" for most things on the islands, but the taxi and bus rates are regulated. Taxi rates are published by the Virgin Islands Taxicab Commission. If you are interested in saving $8, you can walk 3/4 of a mile to Vetern's Drive and catch a safari bus that will take you into town for $1 or $2 dollars if you have minimal luggage.
Taxi rates are charged per person one way. For example, a one way trip from Charlotte Amalie to Magens Bay is $10; round trip for four people will cost $80. If you plan on visiting multiple destinations, renting a car might be more economical.you need to have bus fares too!
By ship
Sailboat rentals at Red Hook will allow you to get around by water. If you plan to sail to the British Virgin Islands, a passport is required as of 2007. Although passports are not required for American citizens to travel to the U.S. Virgin Islands, the Intelligence Reform and Terrorism Prevention Act of 2004 IRTPA has made the documentation requirements much stricter.
On St. John, get the best idea of the island by chartering a boat for a full day. By doing this not only will one get a wonderful day of snorkeling in, but also see the island from a local's perspective. Try St John Yacht Charters at 340-998-9898.
There is a ferry boat that transports cars between Red Hook, St. Thomas and Cruz Bay, St. John. The dock is separate from the passenger ferries. The sign is really small, so if you can't find the dock, ask the workers by the passenger ferries.
Lastly, for a one-stop resource that lists charter companies operating in the U.S. Virgin Islands, consider visiting the Virgin Island Charter Yacht League's site at (http://www.vicl.org). The site lists pictures as well as contact information for charters ranging from monohull to power yacht.
By car
With plenty to explore on all the islands, car rental agencies are recommended. From the lush rainforest to the quaint Christiansted, driving the St Croix island is both scenic and a visual pleasure. Stick to the left-hand side and with a good handful of sharp curves, take your time navigating the roads. Remember that you're on "island time."
Generally car rental rates will be comparable to the mainland U.S. about $500 per week or $80 per day. If you make advanced reservations, the rates are generally lower. Take out the insurance if you plan to go four wheeling up the steep mountain roads. Throughout St. Thomas, there are colored directional signs to major destinations.
Unlike other U.S. territories, traffic on the Virgin Islands moves on the left. To add to the confusion, unlike most other places where traffic moves on the left, most cars in the Virgin Islands are left-hand drive as they are usually imported from the U.S. mainland. Potholes are large and numerous, similar to the end of a particularly snowy New England winter. Drivers often either slow to around 5mph or swing into oncoming traffic when encountering the larger holes. For both reasons, one should always pay extra attention when driving and watch out for drivers who drive on the wrong side of the road. Unmarked one-way streets, very narrow two-ways streets, lack of lane striping, and a high incidence of drunk driving also contribute to the relatively high accident rate among American drivers on the Virgin Islands.
To avoid collisions on hairpin turns in the mountainous areas, stay left and slow to 5mph. Some unpaved mountain roads require four-wheel drive, and some drainage ditches wash across the paved roads in the rain forest. There are generally no sidewalks outside of the towns, so pedestrians and bicycles frequently travel along the side of the main road.
There is a rudimentary highway numbering system. Roads are marked with circular signs. Numbers beginning with 1 and 2 are used on St. John, with 3 and 4 on St. Thomas and 5 to 7 on St. Croix. Roads are not very well marked -- some are not marked at all -- and designations can be confusing. Some roads simply dead-end, or end at an unmarked intersection. Signage can suddenly disappear without warning; for example, heading south on Route 40 into Charlotte Amalie, signage is nowhere to be found as you are shuttled onto one-way streets. It is not uncommon to come to a junction where one must turn to stay on the current road. Locals are more likely to know the names of the roads; conversly, tourist maps usually emphasise the numbers.
