Half Moon Caye, a remote UNESCO World Heritage site in Belize, is primarily accessed via guided boat tours originating from coastal towns like Placencia, Caye Caulker, or Ambergris Caye, typically involving a 1.5-3 hour journey each way; solo visits are impractical due to logistics and cost. The best time to visit is during the dry season (November-May) for optimal weather and sea conditions, though tours operate year-round, weather permitting. A full-day tour, often encompassing snorkeling or diving and sometimes including the Blue Hole, generally costs $150-300+ USD per person, which typically covers transport, lunch, and the mandatory $40 USD park entrance fee. Visitors should expect an 8-10 hour excursion, with 2-3 hours spent on the caye exploring the iconic red-footed booby bird sanctuary, lighthouse, and enjoying the pristine beach. This destination is renowned for its incredible marine life and as a critical nesting site, making it a bucket-list item for nature lovers and divers.
