Separated from the mainland by the Intracoastal Waterway, Jacksonville's main beaches run along the barrier island that includes the laid-back towns of Jacksonville Beach, Neptune Beach, Atlantic Beach, and Ponte Vedra Beach. The northernmost of Jacksonville's beaches, Atlantic Beach is more subdued but a favorite with local surfers. Adjacent Neptune Beach is largely residential and draws bicyclists and in-line skaters who cruise up and down 1st Street. Just south is Jacksonville Beach, which has a decidedly more active shoreline, with volleyballs and Frisbees buzzing through the air and portable radios blaring everything from Kanye West to Van Halen. With multimillion-dollar homes stretching for miles, Ponte Vedra is the most difficult beach to access, but makes for a lovely drive down Route A1A. Lifeguards are on duty on the more populated stretches of the beaches from 10 to 6 in summer.
