I'm visiting Panama next month and I'd like to visit Coiba Island. I've read that there are no lodges there (except ANAM ranger station), but I'm wondering if it's possible to sleep at the Island using our own gears (tent, food, water...) In fact, the same page states:
To get a good impression of Coiba, you should plan to stay there for at least two days
so I suposse that this option should exist. In the case you can camp, you must pay anything? (I've read that there is a $20 fee for entrance, but I don't know if you pay it once or every day).
Note that some people stays overland in Santa Catalina, but I prefer to stay in the Island.
