Why Hike Ernie Maxwell Trail?
Not every Idyllwild hike is a workout. Ernie Maxwell Scenic Trail earns its place on the local shortlist for four very good reasons:
- No permit, no stress. Unlike Devil's Slide or other trails heading toward the Wilderness above Saddle Junction, Ernie Maxwell requires only an Adventure Pass for parking. You can simply show up and go.
- Deep forest immersion. The trail winds through towering ponderosa pines, white firs, and California black oaks. This is the kind of shade-heavy forest that smells like summer camp and keeps temperatures cool even on warm days.
- Truly beginner-friendly grade. With 600 feet of gain spread over 2.6 miles, the trail maintains a gentle 4% average grade. Kids, seniors, and first-time hikers routinely finish this trail without complaint.
- Outstanding bird watching. Bring binoculars to spot mountain chickadees, white-headed woodpeckers, and Steller's jays. During spring migration, a surprising variety of warblers move through this forest corridor.
Getting to the Trailhead
From downtown Idyllwild: Head north on North Circle Drive, then turn right on South Circle Drive. Take Fern Valley Road east for about 1.3 miles until you reach the small dirt pullout and trailhead sign on the left. This is the lower trailhead.
Alternate start at Humber Park: Continue past Fern Valley Road to the end of South Circle Drive. Humber Park has a larger paved lot and toilets. Starting here means you descend to Fern Valley Road, which is a 600-foot trip down through the forest. Many people prefer this as an easier warm-up option.
Parking: Both parking areas require a National Forest Adventure Pass, which costs $5 per day or $30 per year. The Humber Park lot fills fast on weekends by 9:00 AM in the summer, so you should arrive early or start from Fern Valley.
Car shuttle: For the easiest experience, spot a second car at Fern Valley Road and start at Humber Park. You can walk downhill for 2.6 miles and pick up the car when you are done.
Trail Description: Mile by Mile
Miles 0–0.8 (Fern Valley Trailhead to Creek Crossing)
From the Fern Valley Road trailhead, the trail climbs gradually through a mixed forest of pine and cedar. The grade is consistent but never punishing. Within the first half mile, the noise from the road fades entirely and you are surrounded by dense, fragrant forest. Listen for woodpeckers working the dead snags above the trail. Around 0.8 miles, the trail crosses a seasonal stream drainage. In wet winters, this section holds water through April.
Miles 0.8–1.8 (Forest Core)
This is the heart of the hike. The trail levels out in a shaded grove of mature ponderosa pines with a soft, needle-carpeted floor. This is the best birding section of the trail. The canopy here is tall and closed, which creates a cathedral-quiet atmosphere that is unusual for the heavily-used San Jacinto Mountains. Look for large white firs with fire-scarred bases, as these provide evidence of the historic fires that have shaped this forest.
Miles 1.8–2.6 (Climb to Humber Park)
The final section gains most of the trail's elevation as the path switchbacks up toward Humber Park. Views through the trees open up toward Tahquitz Rock and the ridgeline above. The climb is short enough that most hikers barely notice it before the large, paved Humber Park lot comes into view.
Who Was Ernie Maxwell?
The trail bears the name of Ernest Herbert Maxwell (1905–1991), a journalist, conservationist, and Idyllwild pioneer who moved to the San Jacinto Mountains in the 1940s. In 1946, Maxwell founded the Idyllwild Town Crier, which is the local newspaper still in print today. He used it for decades as a platform to advocate for responsible stewardship of the mountain forests. He helped shape the conservation ethos that still defines Idyllwild's identity. Naming this gentle, family-friendly forest trail after him is apt, as it is exactly the kind of quiet, lasting experience he worked to protect.
What to Bring
- Water: Bring at least 1 liter per person, because even easy hikes can dehydrate you.
- Layers: The forest stays 10 to 15 degrees cooler than Idyllwild Village.
- Binoculars: These are essential if you are a birder.
- Dog leash and waste bags: Always clean up after your pets.
- Adventure Pass: You can purchase these at the Idyllwild Ranger Station on Highway 243.
Insider Tips
- Go early on weekends. The Humber Park end fills by 9:00 AM in the summer, whereas the Fern Valley end is almost always quieter.
- Best for winter hiking. Because the trail is at a lower elevation than Tahquitz or Devil's Slide, it is often snow-free when the higher trails are iced over. A light dusting of snow on the pines here is magical.
- Plan for a nice dinner. The trail is close enough to downtown Idyllwild that an afternoon hike followed by dinner at Café Aroma makes a perfect day. This nice restaurant is now a dedicated dinner spot that offers great food and frequent live music. Because it is always booked up, you will definitely need to make reservations. Please note that they no longer serve breakfast or function as a coffee shop.
- Bring the dog. This is one of the few easily accessible Idyllwild trails where dogs are explicitly welcome. Keep them leashed, as wildlife is active in this forest year-round.
FAQs
Q: Is Ernie Maxwell Trail a loop? No. It is a point-to-point trail connecting Fern Valley Road (lower) to Humber Park (upper). You can hike it as an out-and-back for 5.2 miles total or as a one-way shuttle hike if you have two cars.
Q: Do I need a permit for Ernie Maxwell Trail? No wilderness permit is required. You only need a National Forest Adventure Pass for parking, which is available for $5 per day at the Idyllwild Ranger Station on Highway 243.
Q: Is Ernie Maxwell Trail dog-friendly? Yes, dogs are allowed on a leash. This is one of the reasons it is popular with locals, as pets can enjoy the forest without the permit restrictions that apply to the higher wilderness trails.
Q: How does Ernie Maxwell compare to Devil's Slide? It is much easier. Devil's Slide is 5 miles round-trip with 1,700 feet of gain and requires a wilderness permit. Ernie Maxwell is shorter, at a lower elevation, requires no permit, and is less exposed. It is the right choice for beginners, families, or anyone who wants forest time without a major climb.
Q: Is Ernie Maxwell Trail open year-round? Generally, yes. The trail sits at a lower elevation than the wilderness trails above Humber Park, so it stays accessible through most winters. After heavy snowfall, you should check with the Idyllwild Ranger Station for current conditions.
Q: What is the best direction to hike Ernie Maxwell Trail? Starting at Humber Park and hiking down to Fern Valley Road is slightly easier because you do the 600-foot descent first. Starting at Fern Valley Road and hiking up to Humber Park means you finish at the larger parking area with toilets, which is a practical consideration.
