Grand Isle travel guide

Grand Isle is a town in Jefferson Parish, Louisiana, on a barrier island of the same name. The island is at the mouth of Barataria Bay where it meets the Gulf of Mexico. As of the 2000 census, the town population was 1,541; during summers, the population has increased to over 20,000.
Grand Isle's only land connection to the mainland is via an automobile causeway bridge, near the west end of the island, which connects it to southern Lafourche Parish, Louisiana. Also a point of interest, to reach the rest of Jefferson Parish by roadway, one has to travel through two different parishes (Lafourche and St. Charles) through a total distance of about 95 miles.
Grand Isle State Park, on the east end of the island, is the only state-owned and operated beach on the Louisiana Gulf Coast, a beach frequented by people from the Greater New Orleans area. (...) more....
