Ernie Maxwell Scenic Trail Hiking Guide
Almost every trail out of Idyllwild goes straight up. The Ernie Maxwell Scenic Trail is the exception, and that makes it disproportionately valuable. It runs roughly two and a half miles each way between Humber Park and the Saunders Meadow area, contouring through pine and cedar forest with modest rolling gain, no permit requirement, and shade for essentially its entire length. It is the trail to bring people on who are not sure they like hiking yet.
A Trail Built for Walking
Named for the founder of the local newspaper and a longtime advocate for the San Jacintos, this trail was laid out to be enjoyed rather than to reach a summit. The grade is gentle throughout, the tread is soft duff and decomposed granite, and the forest canopy is nearly continuous. It is a hiking-only trail, which keeps it quiet, and it works equally well as a one-way with a car shuttle or an out-and-back turning around whenever you feel like it.
Trailheads and Direction
The upper end is at Humber Park, the busy trailhead that also serves Devils Slide and the routes into the high country; the lower end is near Saunders Meadow Road on the edge of town. Starting at Humber Park means a gentle downhill on the way out and a modest climb back, which most people prefer. Parking at Humber Park requires an Adventure Pass and the lot fills early on weekends because of the wilderness trails leaving from the same spot. The lower trailhead has limited roadside parking.
No Permit, Which Matters Here
Because the trail stays outside the San Jacinto Wilderness boundary, no wilderness permit is required — a genuine convenience in an area where nearly every other option needs paperwork. That makes it the natural fallback when wilderness permits are unavailable, when you arrive in Idyllwild without a plan, or when you have someone in the group who is not up for a permit-and-altitude expedition. It is also the best option for a late-afternoon walk when the ranger station has closed.
Forest and Season
The route passes through mature Jeffrey pine, incense cedar, and black oak, with seasonal creeklets crossing in spring. Late spring through fall is prime, with summer notably cooler here than the valley floor below. Autumn brings color in the oaks and the dry, clear air the San Jacintos are known for. Winter snow makes the trail a pleasant snowshoe, and because the grade is so gentle it stays manageable in conditions that would make the steeper local trails dangerous.
Who It Suits
This is the Idyllwild trail for kids, for older family members, for a recovery day between bigger objectives, and for anyone still adjusting to 5,000-plus feet. Leashed dogs do well given the shade and easy footing. It is also an excellent trail-running route for the same reasons. There is no water along the way and no facilities beyond those at Humber Park, and cell coverage is patchy. The main hazard is simply the altitude catching out visitors who assume an easy grade means an easy day.
Hiking tips for Ernie Maxwell Scenic Trail
- Start from Humber Park for a gentle downhill out and a modest climb home, which most groups find easier than the reverse.
- Use this as your fallback when San Jacinto Wilderness permits are unavailable — it stays outside the boundary and needs none.
- Arrive early for Humber Park parking; the lot fills with wilderness hikers well before mid-morning on weekends.
- Consider it in winter as a snowshoe, since the gentle grade stays safe in conditions that make Idyllwild's steep trails hazardous.
- Do not let the easy profile fool you about the altitude — visitors from sea level still feel 5,500 feet on a flat trail.
