This dive site, Cottrell Key, is one of three mangrove islands situated approximately 9 miles northwest of Key West. It forms a crucial part of the Key West National Wildlife Refuge, serving as a vital nursery for numerous newborn and juvenile marine species. The site is characterized by its very shallow depths, averaging around 3 meters and reaching a maximum of 7 meters, making it less suitable for traditional deep scuba diving but excellent for surface activities. There is no specific historical information regarding navigation or significant stories beyond its ecological importance as a protected area.
The unique ecosystem of Cottrell Key is home to a diverse array of marine life, particularly focusing on the younger stages of many species. Visitors can expect to see various juvenile fish, crustaceans, and potentially some unique species like the rare batfish, which finds refuge in these protected waters. The extensive mangrove roots provide shelter and food, fostering a rich environment for observation of developing marine organisms.
Cottrell Key is best visited during calm weather to maximize visibility and enjoyment, though its shallow nature makes it relatively accessible year-round. It is an ideal spot for snorkelers and freedivers looking to observe a vibrant nursery ecosystem without the need for extensive dive gear. Photographers interested in macro subjects and juvenile marine life will find this site particularly rewarding. Due to its protected status within the wildlife refuge, respectful interaction with the environment is paramount.
