During a day trip (in a hybrid vehicle, natch) guests can participate in tree planting, recycling projects and exotic plant removal. After lunch, they can also explore walking trails and even wade through a swamp. Although they better be careful – the park’s home to the endangered American crocodile.
(I once waded through the Fakahatchee State Park, near the Everglades. And every time my foot bumped into a root beneath the dark-tea-colored surface, I nearly jumped straight out of the water.)
But I'm sure no harm will come to a voluntourist. The package, which includes two nights at the hotel, starts at $698 from May 24, 2009 through September 30. Prices higher at other times of year.
