Grand isle is primarily a fishing destination. That time of year you almost have to some kind of access to a boat to catch any substantial number of fish. Later in the summer and early fall is best for bank fishing. If you’re going for good seafood restaurants, you can find some of the worst there. If you cook your own and you come while the season is open you can get incredible shrimp, oysters and blue crabs. Shrimp right off the boat are so fresh they’re cheap. Good restaurants are nearby but not so much on the island. The Hurricane Hole is probably good but it’s pricey.
The state park is roomy and well kept. The beach is a short walk across the levee. There are a couple of piers into the water and a walking path around the lagoon that’s interesting.
If you like to fish it can’t be beat. We love Grand Isle and go frequently.
If you’re looking for a stop on the way down the bayou and good restaurants try Bayou Segnette State Park. Just a few minutes from the French Quarter and the best seafood you’ll have in this country. The WWII museum is very worth at least a day trip. Don’t miss the movie! Sooo worth it!
Have fun! Hope to see ya on the island!!!
