A second Torrey Pines: Hiking Torrey Pines State Natural Reserve can get crowded, but there’s a nearby annex that’s far less populated and and still offers ocean views. Four different entrances get you into the Torrey Pines Extension, a five-trail island of green surrounded by suburbia. For the southernmost entrance, take the Carmel Valley Road exit off I-5 and head west. Turn right on Del Mar Scenic Parkway and continue to the end and park in the cul de sac. Oh, and parking? Free.
