Torrey Pines State Reserve, La Jolla
This State Reserve was set aside to protect the natural landscape of this part of California, especially protecting the rarest pine tree in the world, the Torrey Pine which grows here naturally. (The only other place it grows naturally is up near Santa Barbara.)
While visiting Torrey Pine State Reserve, you should know that it is for day use only--no camping or over night stay. (Open from 8:00 am to sunset.)
You must stay on the trails--there are miles and miles of trails. You may not take away any souvenirs--not even a pine cone. You are allowed and advised to bring drinking water, but no food can be eaten in the Reserve--You may bring food with you to eat down at the beach. Well, check out the website for all the specifics.
There are four or five trails to hike, some of which offer fantastic panaramic views. There is a Visitor Center (Open 9:00 am to sunset) and on weekends and hoildays guided tours are offered.
Just below is Torrey Pines State Beach, a great way to cool off from all that hiking up, down and around.
