The bicycle path which runs from Santa Monica to Redondo Beach Pier has always been one of my favorite places to ride. It runs 18 miles along the coast through the beaches of LA and next to the ocean. My husband and I make a point of doing the ride from Santa Monica to Redondo several times a year and hook up with a large group of friends every Memorial Day.
Depending on which section you ride, the total trip can range from 14 to 38 miles and is a guaranteed "all-day" adventure. If you choose to begin in Santa Monica, there are plenty of parking lots along Neilson Way ($7.00/all day). If you don't want to bring a bicycle with you, you can rent from one of the many vendor's at the beach Bike Rentals
Along the way, there are restaurants and shops and there are alot of things to see so be sure to bring bike locks, cash, sunblock, windbreaker, water, sunglasses and a bike pump (in case of a flat) and you will be set!
