Depart St. Thomas for a visit to the smallest of the US Virgin Islands, St. John, and take in the history of the island as well as its majestic natural beauty on this half-day tour. See an old Danish sugar plantation, a national park, and various lookouts along the way.

Start by boarding a ferry that takes you across the short 4 miles (6.4 km) of water between St. Thomas and St. John, where your tour bus awaits you. With your local guide, stop first at the Virgin Islands National Park to take in beautiful mountain vistas, impossibly blue water, and verdant coastal greenery. Enjoy the panoramic displays of white-sand beaches meeting mountain forests at your next 2 stops, Caneel Bay and Trunk Bay.

At Annaberg, see the remnants of a 1780s sugar mill plantation. Wonder at the ruins of the factory, windmill, and slave quarters as you learn about the island's Danish settlers. Finish with a drive back to the ferry terminal for your cruise back to St. Thomas.
