City & Place Guide

Rugged gem of the southern Grenadines, untamed and unforgettable.

Union Island is the southernmost inhabited island of Saint Vincent and the Grenadines, sitting just 40 miles from Grenada. Known for its dramatic terrain, including the striking peak of Mount Taboi, it attracts sailors, kitesurfers, and travelers seeking an off-the-beaten-path Caribbean experience.

The main settlement, Clifton, serves as the island's commercial and social hub, with a small harbor bustling with yachts, fishing boats, and inter-island ferries. Ashton, the second village, offers a quieter pace and access to beautiful anchorages.

Despite its small size, Union Island punches above its weight with vibrant local culture, a celebrated Easter Regatta, and proximity to the uninhabited Tobago Cays Marine Park, making it a beloved stop on the Grenadines sailing circuit.

  • •Mount Taboi — hike to the island's highest point for panoramic Grenadines views
  • •Clifton Harbor — colorful working port with local life, restaurants, and yacht watching
  • •Chatham Bay — secluded anchorage with a pristine beach and exceptional snorkeling
  • •Kitesurf Paradise at Ashton — world-class flat-water lagoon drawing kitesurfers globally
  • •Tobago Cays Marine Park — nearby protected marine reserve with sea turtles and coral
  • •Big Sand Beach — calm, quiet stretch of white sand ideal for relaxed swimming

Getting around: Union Island has no rail system. Within the island, shared minibus taxis run between Clifton and Ashton for a modest fare, and private taxis are readily available for hire. Water taxis connect the island to nearby cays and neighboring Grenadines. Renting a bicycle or walking is feasible given the island's small scale.

Best time: The dry season from December to May offers the most reliable sunshine, calm seas, and ideal sailing and kite conditions.

Local food: Try fresh grilled lobster and fish at Clifton's waterfront spots, along with local staples like roti, saltfish, and provisions cooked in traditional Vincentian style.
