Once home to a world-renowned fishing resort that was destroyed by the 1935 Labor Day Hurricane, Long Key remains a popular fishing destination today, with several resorts to accommodate visitors. Layton, the smallest city in Monroe County at just 85 acres and fewer than 200 people, is on Long Key. Its proximity to the Channel 5 Bridge makes boating access to the ocean or bay only a 15-minute trip, even for sailboats. Tennessee Reef, located less than five miles offshore, is a popular diving and fishing spot. Layton is home to the Keys Marine Lab, which serves students and researchers from around the world. The 1,000-acre Long Key State Park is one of four state parks in the Keys that welcomes tent and RV campers, with 60 sites overlooking the Atlantic Ocean.
