Palomar Mountain State Park
One of the few areas in Southern California with a Sierra-like atmosphere, the park is carpeted with a forest of pines, cedars, western dogwood, native azalea, and other plants. Wildflower viewing is good in spring. Boucher Lookout, on one of several nature/hiking trails, affords a sweeping view to the west (closed in winter). There's trout fishing in Doane Pond. The Doane Valley campground offers 31 sites with tables, firepits, and flush toilets. From May to October, reservations are strongly recommended and can be made seven months in advance.
