In addition to the trails at St. Lucie Lock and Dam, visitors can enjoy walking, hiking, rollerblading, bicycling and horseback riding around Lake Okeechobee. Designated as part of the Florida National Scenic Trail in 1993, the Lake Okeechobee Scenic Trail (LOST) is an approximately 110-mile trail encircling the lake. More than half of the trail is paved, and the remainder consists of a two-track gravel roadway on top of the 35-foot high Herbert Hoover Dike.
