Located in the Santa Rosa mountain range, the yellow post campsites of Little Thomas are free and offer very minimal amenities. Depending which site you have there's a picnic table. Not much shade on any of the sites so be prepared if going in the summer. To get there, turn off on the dirt road located just passed Lake Hemet on 6S13. The first site is on the left side just after you pass the gate. About 0.25 miles. It's super close to Lake Hemet so if you need anything you forgot, you can go quickly to the store. It's also only a 15 min drive to Idyllwild which makes it a great place if all the campgrounds are full.
