The Great Blue Hole in Belize is a world-renowned underwater sinkhole, famous for its stunning deep blue color and diverse marine life. Access is primarily via boat from nearby coastal towns like Caye Caulker or San Pedro. Scuba diving or snorkeling are the main activities, with diving being more suitable for experienced divers due to the depth. Visibility varies, but it's generally good. Guided tours are highly recommended, especially for divers, to ensure safety and maximize the experience. There are generally no seasonal restrictions, but weather conditions can impact boat tours; the dry season (December to April) usually offers the best conditions. The cost for a day trip, including boat transport, diving/snorkeling fees, and equipment rental, can range from $200-$400 USD per person. A typical visit lasts a full day, including travel time to and from the site. Accessibility for individuals with mobility issues is limited due to boat transfers and the nature of the activities.
