The boardwalk is a natural draw for bicyclists. Beach cruiser bikes can be rented at several places on the Balboa Peninsula. Bicyclists are also drawn to Back Bay Drive and the bike paths around Upper Newport Bay; the hilly roads winding through Newport Coast and the San Joaquin Hills; and the mountain biking trails in the San Joaquin Hills and Crystal Cove State Park. Pacific Coast Highway provides access to these areas and is a major bicycle route through the region, despite being shared with heavy motor vehicle traffic.
