Bolsa Chica is located just south of Sunset Beach and north of Huntington Beach.  From the 405 Freeway, take Bolsa Chica Blvd. south about 5 miles to Warner.  Turn right on Warner, and follow it around to Pacific Coast Highway.  There is a Jack in the Box at the corner.  Turn left, and drive south one mile to the traffic light.  Turn into the State Park and (after you pay $5.00) turn to the right and drive back in the direction of the Jack in the Box until you come to Life Guard Station 24.  Look around, we will be there!
Mapquest Map  Note:  Lifeguard Station 24 should be marked on this map.  If not, then it would be about where the "C" is in the words "Pacific Coast Hwy" on the map.
