Grand Isle State Park is @ the end of La. 1. It's actually part of Jefferson Parish, not Lafourche. Watch the speed limit signs, and obey them--especially when going through Golden Meadow (which you'll have to drive through to get to the Isle. There is some road construction going on in Leeville (another town you'll be driving through en route--they're building a new bridge to Port Fouchon--stop and grab a bite to eat @ Anthony's restaurant--the food is great). The island has suffered some hurricane damage throughout the years, but these are tenacious people--they don't give up easily. There are homes and camps of varying states of repair and disrepair, and surprisinly really nice camps--some of which can be rented out. There are a few motels, but i would advise a camp if sleeping on the beach is not your thing. It's not a touristy town @ all. There is one huge event that takes place in the last wknd of July--The Grand Isle International Tarpon Rodeo--which is a huge fishing rodeo. It always attracts a large crowd of locals, tourist and die-hard fishermen!! There's a lot of partying going on that wknd and if you don't plan way ahead you can forget about finding anywhere on the island to stay. The park itself has overnight facilities, a picnic area, and showers. You'll have to park your vehicle in a lot in front of the showers as there are no vehicles allowed on the beach in that area. It had an observation tower and fishing pier, but I haven't been back since the last hurricane so I don't know if those have been rebuilt or not. From the pier you can see the ruins of an old British fort which I believe may have been utilized during the Battle of 1812. You may even be able to charter a boat to get a closer view of the fort. If camping in the park, check the wind direction--we had a strong wind coming in from the gulf and had to keep repitching our tent because it kept blowing down over us. It was funny as heck--I thought so, but my then-husband was miserable the whole time. That was the best camping trip I ever had. Although I think he would beg to differ!!
