St. Herman's Cave, located within the Blue Hole National Park, offers a unique cave exploration experience in Belize. While the initial sections are accessible via a maintained trail and can be explored independently, venturing deeper or engaging in cave tubing strictly requires a licensed guide for safety and adherence to park regulations. The cave is generally open year-round, though heavy rainfall during the wet season (June-November) can lead to higher water levels, potentially affecting accessibility or specific activities. Park entrance costs around $4-5 USD, but guided tours, especially those including cave tubing, can range from $75-150+ USD per person. A typical visit duration is 1-2 hours for basic exploration, extending to a half-day if combined with cave tubing or exploring other park features like the Inland Blue Hole. Visitors should wear sturdy shoes, bring a flashlight or headlamp, insect repellent, and a change of clothes, as the cave involves uneven terrain and can be wet.
