I've got an overnight in the Naples / Fort Myers area coming up and am considering a trip to the Everglades, but don't really want to drive across to the Miami side of the park. I see another thread here about airboat operator recommendations - but the questions / answers there seem to all be Miami-side, and I also see various comments about Shark Alley which also sounds quite something.

But is there anything like those coming in from the Everglades City end? Trail walks, hire-a-bike, airboat rides etc?
