Clifton, Union’s bustling port, is a good place to re-provision before your trip further down the island chain. Visit the collection of sharks in the pool at the Anchorage Hotel, or take a browse through the many local boutiques.

Union Island is dramatically mountainous, but also has its share of reefs and bays. Snorkelers will find good conditions on Lagoon Reef, which protects most of the southern coast of the island. Chatham Bay is another protected anchorage, and Bloody Bay on the northwest coast offers captivating views and a long sandy beach.
