The Five Islands can be found rising above the flat Louisiana Gulf coast about 225 km from New Orleans in Louisiana. The islands - Avery, Weeks, Côte Blanche, Belle Isle and Jefferson - are circular topographic prominences from one to two miles in diameter, rising 23 meters or more above the surrounding marshlands. Avery Island stands the highest at 46 meters above sea level and is well noted for its bird sanctuaries, gardens and cayenne pepper production. The islands are famous for salt, oil and gas production and are notable tourist attractions.
The islands are copiously vegetated and support a rich wildlife, including the Louisiana black bear and nutria imported from South America. Tropical gardens have been cultivated on Jefferson and Avery islands, and the latter is home to the world-famous Tabasco sauce and also houses a rare-bird sanctuary and exotic tropical plants.
