Oh, Newport Back Bay Loop. The trail branches off from Harvard Avenue's separate bikeway and loops completely around the Back Bay. The majority of the 10.5-mile loop is an easy ride protected from traffic and flanked by salt-tinged ocean waters and refreshing sea breezes. It can be done in one go, or with multiple rounds along several vistas and educational centers. Cyclists looking for a longer ride can even add a chunk of the Mountain to Sea trail, which stretches all the way to Tustin, or hop a Balboa Island ferry and head to the peninsula.
