Coiba Island, a UNESCO World Heritage site and part of Coiba National Park, is a premier Panamanian destination, primarily accessible by boat from coastal towns like Santa Catalina (1-2 hour journey). Guided visits are mandatory due to park regulations, ensuring visitor safety and environmental protection; solo exploration is not permitted beyond designated areas. The dry season (December-April) offers optimal conditions with calm seas, though the wet season (May-November) can provide excellent wildlife viewing, especially for whale sharks (July-September), and the park generally operates year-round, weather permitting. A full-day tour typically costs $100-$200+ USD per person, including boat transfer, park fees, and gear, while multi-day options are more expensive. Most visitors spend a full day, but 2-3 day trips are recommended for a comprehensive experience, offering multiple dives/snorkels and wildlife encounters in this remote, biodiverse marine park.
