The rare torrey pine tree grows only two places in the world: Santa Rosa Island, 175 miles northwest of San Diego, and here, at the north end of La Jolla. Even if the twisted shape of these awkwardly beautiful trees doesn't lure you to this spot, the equally scarce undeveloped coastal scenery should. The city first donated 369 acres as a public park, and the 1,750-acre reserve was established in 1921, from a gift by Ellen Browning Scripps. The reserve encompasses the beach below, as well as a lagoon immediately north, but the focus is the 300-foot-high, water-carved limestone bluffs, which provide a precarious footing for the trees. In spring, the wildflower show includes bush poppies, cleveland sage, agave, and yucca. A half-dozen trails (all under 1 1/2 miles in length) travel from the road to the cliff edge or down to the beach, and there's a small visitor center, built in the traditional adobe style of the Hopi Indians and featuring a lovely 12-minute video about the park. Watch for migrating gray whales in winter, or dolphins who patrol these shores year-round. For a taste of what Southern California's coast looked like a couple hundred years ago, this delicate spot is one of San Diego's unique treasures. Note: There are no facilities for food or drinks inside the park--bring a picnic lunch.
