A bit over an hour’s drive southeast of Lake Elsinore via Temecula, Palomar Mountain State Park offers campgrounds surrounded by scenic views, birdwatching opportunities, and nighttime stargazing. Cleveland National Forest is right there too, with designating campsites, dispersed camping, and hiking trails. Keep going to hit Anza-Borrego Desert State Park, known for its vast desert landscapes, wildflower blooms, and campsites.
