Brimstone Hill Fortress National Park, a UNESCO World Heritage Site on St. Kitts, offers a captivating glimpse into Caribbean military history. The fortress is partially accessible, with some areas reachable by wheelchair, though steep inclines and uneven surfaces pose challenges. It's suitable for both solo exploration and guided tours, the latter providing deeper historical context. The park is generally open year-round, but check for specific holiday closures. Expect to spend 2-3 hours exploring the grounds. Entry fees are approximately $15 USD for adults and $8 USD for children. Consider bringing water and wearing comfortable shoes for walking.
