Explore Charlotte Amalie [1] on foot or by taxi. The rest of the island is best explored by car. The countryside is widely developed, with the exception of the west end. Highways are generally well maintained, but routes are confusing and traffic can be very heavy. Drivers make liberal use of their horns and hand gestures to communicate with other drivers.
To reach the east end, take Route 30 (Frenchman’s Bay or Bovoni Road), which follows the southeastern coast, runs into Route 32 (Red Hook Road), and continues along the shoreline past the best beaches and large resorts before becoming Route 30 (Smith Bay Road).
To get to the north shore, take Route 35 (Mafolie Road) and follow it to Magen’s Bay [2]. Route 40 (Valdemar Hill Drive, also called Skyline Drive) follows the island’s backbone from Charlotte Amalie [1] to the east end. Take Route 30 as far west as you dare to explore the west end.
