Grand Isle State Park, lies at the eastern end of Grand Isle, Louisiana, USA. Grand Isle is the only inhabited barrier island in the state. The park has been seriously affected in the past by Hurricanes Katrina, Gustav and Ike. However, much of Grand Isle State Park has been renovated. Beach restoration in the area is ongoing. At one time, the park's fishing pier was especially popular but it was destroyed in 2005 by Hurricane Katrina and has yet to be rebuilt. An observation tower provides fine views of the surrounding coastal scenery. Visitors come to 160-acre (0.65 km2) Grand Isle State Park to beachcomb, birdwatch, boat, camp, crab, fish, and sunbathe.
On May 22, 2010, the beach was shut down due to oil contamination from the Deepwater Horizon oil spill. On May 3, 2011 a portion of the beach was reopened. On June 26, 2011 volunteers, organized by The Coalition to Restore Coastal Louisiana, planted 1,600 black mangrove trees along the coast to prevent erosion.
