St. Herman's Blue Hole National Park in Belize offers an immersive natural experience, easily accessible by car, with parking available near the visitor center. Visitors can explore the stunning inland Blue Hole cenote and the extensive St. Herman's Cave; while the park's trails to the Blue Hole can be enjoyed solo, exploring St. Herman's Cave requires a licensed guide for safety and information, making it suitable for both independent adventurers and those preferring guided experiences. The park is open year-round, though the dry season (December-May) is optimal for avoiding muddy trails and potential cave closures due to heavy rains. Entrance fees are typically $4-10 USD per person, with additional costs for guided cave tours (approx. $25-50 USD per person for St. Herman's Cave). A typical visit to the Blue Hole and St. Herman's Cave lasts 2-4 hours; useful tips include wearing sturdy shoes, bringing insect repellent, water, and swimwear, and being prepared for potential wading and climbing in the cave.
