Day trips outside of town:
Swamp tours: those with a car can make an easy day trip to the Jean Lafitte Nature Preserve, a free park, with as good a view of local swamp flora and fauna as various pay tours. Honey Island Swamp Tours Inc. - nearly 70,000 acres of the Honey Island Swamp is a permanently protected wildlife area. Jean Lafitte Swamp Tours - Cajun-style boat tour takes you out on an 1 hour and 45 minute trip through the heart of Southern Louisiana's swamplands. Some swamp tours also have vans that can pick you up at your hotel and take you to the swamp tour location, though this can be significantly more expensive option than driving yourself.
