Bowen Ranch provides the easiest access to Deep Creek, which are some of Southern California's favorite hot springs. The free route is 5 miles along the Pacific Crest Trail, so the shorter hiking option (2.6 miles from Bowen Ranch) is worth the entry fee.
The springs are located on BLM land, but privately-owned Bowen Ranch provides the closest camping, as overnight stays are not allowed at Deep Creek. The owners charge a fair $10 per night (which includes the normal entry fee) to camp on their property for multi-day enjoyment of the hot springs.
The rustic campsite does not include any amenities, and all trash must be packed out. Bring plenty of drinking water and other supplies, because the site is remote from any services. The ranch does not take reservations, and it does sometimes fill up on busy weekends, so arrive early to secure your spot near the paradise of Deep Creek Hot Springs.
