This perfectly planar stretch of sand was once the city's raceway. Sections of the beach still welcome drivers to the sands at a strictly enforced top speed of 10mph. The most popular strip is a one-way stretch heading south between International Speedway Blvd and and Dunlawton Ave. Beachside rentals for ATVs, fat-tired cruisers, recumbent trikes and all manner of water sports are ubiquitous. Of course, you're free to frolic anywhere on the beach, off the roadway.
