Deer Springs Trailhead (Idyllwild)
You need two different things here, and people forget the second. To park at the Deer Springs Trailhead — on Highway 243 about a mile north of Idyllwild — you display an Adventure Pass ($5/day, $30/yr, or an interagency pass). To hike it, you also need a free self-issue wilderness permit for the San Jacinto Wilderness, filled out at the trailhead box or the Idyllwild ranger station. The lot is small and fills early on summer weekends; no dogs in the wilderness.
The facts
- Trail served
- Deer Springs Trail to Suicide Rock (~7 mi RT) and on to San Jacinto Peak & Little Round Valley (strenuous, ~16 mi RT)
- Cost / pass
- Adventure Pass ($5/day, $30/yr) or Interagency pass to park; free self-issue day-use wilderness permit to hike ($5/person only for overnight camping)
- Lot size
- Small paved/dirt trailhead lot on Hwy 243 — a couple dozen cars before it spills to the roadside
- When it fills
- Summer and fall weekends: early morning, especially for a peak attempt
- Overflow option
- Limited roadside on Hwy 243 shoulders — park fully clear of the lane; the Marion Mountain Trailhead nearby is an alternate start
- Tow / citation risk
- Hwy 243 is a mountain highway; don't block it. Citations are for a missing pass or permit as much as for parking
- Restrooms
- None at the trailhead; restrooms and the ranger station are in Idyllwild
- Road to the lot
- Paved: Highway 243, about 1 mile north of Idyllwild
- Busy season
- Late spring through fall for the peak; snow and ice linger up high into spring (traction gear needed off-season)

Highway 243, ~1 mi north of Idyllwild, CA 92549
Get directions →The two-piece paperwork, explained
Deer Springs requires two things. For parking, display an Adventure Pass or America the Beautiful pass; it is a Forest Service fee site. For access, carry a wilderness permit because the trail enters the San Jacinto Wilderness and, higher up, San Jacinto State Park Wilderness. Day-use permits are free and self-issued at the trailhead register or 24/7 at the San Jacinto Ranger Station, 54270 Pine Crest Ave, Idyllwild, (909) 382-2921. Overnight permits cost $5 per person and are more limited.
Bring both the parking pass and the permit.
Where it goes and why the lot fills
Deer Springs is one of Idyllwild's best-value trailheads because a single lot serves several classic hikes: the moderate climb to Suicide Rock (about 7 miles round trip, big granite views), and the long, serious push to San Jacinto Peak by way of Little Round Valley — a ~16-mile day with roughly 4,400 feet of gain that separates the acclimated from the optimistic. Because it feeds both a popular half-day hike and a bucket-list summit, the small lot fills early on any decent-weather weekend, and summit hikers are often starting in the dark.
No dogs are allowed in the wilderness here. If Deer Springs is full, the nearby Marion Mountain Trailhead (the shortest route to the peak) is the usual fallback — same Adventure-Pass-plus-permit rules apply.
