Run by a couple of keen Dutch biologists, these superb guided tours use local fishing boats. Package trips include snorkeling at four to five reefs, hiking on two trails, a boat ride through mangroves, birding and wildlife-watching. More tailored visits are possible in the low season.

Tours depart from Palo Seco, north of Malena on the Sunset Coast, and require a two-guest minimum. Tours include park entry, meals, accommodation at their B&B and in double-occupancy tents on Coiba, avoiding the shared dorm. Book early so they can plan snorkeling to coincide with the best tides. Rates are discounted with larger groups and in low season. Very family-friendly.
