The only way to get to and from St Helena at the moment is via the mail ship, RMS St Helena. The airport at Prosperous Bay Plain has been open to medical evacuation and chartered flights since May 2016 but commercial flights are still to be confirmed. The easiest way to get around the island is by renting a car. Limited taxi and bus services are available, however, it’s advised to check rates and times before travelling. There is no train service on the island. On the island, as it is in the UK and South Africa, vehicle’s drive on the left hand side of the road. Most roads are single lane; as a result local custom dictates that the vehicle driving downhill should make way for upcoming traffic. Unless otherwise stated, speed limits are 30mph (48 Km/h) on most roads and restricted to 20mph (32 Km/h) in Jamestown. Drinking & driving is not tolerated, and laws are strictly applied. The current limit is 50μg of alcohol per 100ml of breath. Cruise ships call on a regular basis, and facilities are available for yachts. Further details of cruises and yachting facilities are available from St Helena Tourism.
