Overview
Sleeping Beauty is one of those summits that rewards you more than the mileage suggests. At just 3.4 miles out and back, you might expect a modest walk with decent scenery. What you actually get is a steep, direct climb to a rocky volcanic knob at 4,907 feet, capped by a short scramble and a view that takes in three of the most iconic peaks in the Pacific Northwest.
On a clear day, the summit places Mt. Adams directly to the north (less than 20 miles away), Mt. Rainier to the northwest, and Mt. Hood to the south across the Columbia River Gorge. Below the summit, the flat agricultural expanse of the Trout Lake Valley contrasts sharply with the forested ridgelines surrounding it. It's a geography lesson in volcanic tectonics delivered from a 360-degree perch.
This trail stays relatively unknown compared to other Gifford Pinchot destinations like the Lewis River corridor or the Mount St. Helens sites including Ape Cave and Norway Pass. The dirt road access keeps casual visitors away, and the short but demanding climb filters out those looking for an easy stroll. If you can handle 1,400 feet in 1.7 miles and a brief rocky scramble, this summit is worth every step.
Dogs are welcome on this trail on leash. The scramble section at the summit is manageable for most dogs, though small or older dogs may need help on a few of the larger rock steps.
Getting to the Trailhead
From Trout Lake, WA, head north on WA-141 briefly, then turn north onto Forest Road 88. Follow FR 88 and its connector roads to Forest Road 8810. The trailhead is roughly 12 miles from downtown Trout Lake. The first several miles of FR 8810 are passable in a standard passenger car, but the final 2 to 3 miles feature ruts, loose rock, and a narrow road surface. A high-clearance vehicle or a truck with decent ground clearance is strongly recommended. In a low-clearance car, you risk bottoming out on the exposed road crown.
The parking area is small (roughly 8 to 10 vehicles) and unpaved. There are no restrooms at the trailhead. A Northwest Forest Pass is required for parking.
From Portland, the total drive is approximately 100 miles and runs 2 hours and 15 minutes to 2 hours and 30 minutes depending on your route through the Columbia River Gorge.
The Route
Trailhead to the Forest Climb (0.0 to 0.7 miles)
The trail begins in second-growth Douglas fir and enters a moderate climb almost immediately. There's no warm-up period: the grade starts earnest within the first quarter-mile and stays that way. The forest is dense enough to provide shade, which matters on hot summer afternoons on the south-facing slopes.
The path is well-defined and easy to follow, marked with occasional blazes on the trees. The switchbacks are minimal; this trail mostly goes straight at the slope, which is both direct and tiring.
Steeper Middle Climb (0.7 to 1.5 miles)
The gradient increases through the middle section as the trees begin to thin. Views start appearing through gaps in the forest to the south and west, giving you early glimpses of the Columbia River Gorge ridgelines. By 1.2 miles, you're high enough to see Mt. Hood's distinctive cone to the south on clear days.
The trail surface transitions from dirt to a mix of dirt and volcanic rock. Footing is generally solid, but loose gravel accumulates on steeper stretches. Trekking poles help here, especially on the descent.
Summit Scramble (1.5 to 1.7 miles)
At roughly 1.5 miles, the formal trail gives way to a rocky scramble on the summit knob. The final 0.2 miles gains another 150 to 200 feet over exposed basalt and volcanic rock. This is rated Class 2: hands are useful in a few places to steady yourself, but there's no genuine technical climbing. The rock is stable and the route is intuitive. Follow the path of least resistance and you'll find the summit without difficulty.
One note on the summit scramble: the rock faces west and north, which means it dries quickly in summer sun. In wet conditions (early season or after rain), the rock can be slick. Early June trips that follow heavy rain deserve caution on this final section.
The summit itself is a flat-ish rocky plateau, roughly 40 feet across, with nothing blocking the view in any direction. A register canister has been placed there by previous hikers.
The Return (1.7 to 3.4 miles)
Return the way you came. The descent is steep enough that trekking poles pay for themselves on the way down. Take your time on the rocky sections: the footing that felt manageable going up can catch you off guard while looking at the view behind you.
Most hikers complete the round trip in 2 to 3.5 hours depending on pace and time spent at the summit.
Permit Requirements
A Northwest Forest Pass is required for trailhead parking. Day passes cost $5 and annual passes run $30. Passes are available online through Recreation.gov and at many outdoor retailers near the Columbia Gorge and Mount Adams areas. No wilderness permit is required for this hike.
When to Hike
June: The trail typically opens in mid-June once snow clears the access road and upper summit area. Early season visits often find remnant snow patches on the north-facing side of the summit knob. The scramble section can hold icy patches well into June in heavy snow years. Check recent trip reports before heading out.
July and August: The ideal window for clear summit views, with reliable road access and dry rock. The caveat: wildfire smoke can blanket the southern Cascades in drought years, sometimes reducing visibility dramatically from mid-July through September. Check air quality and smoke forecasts before making the drive.
September and October: Excellent hiking conditions. Smoke typically clears after the first fall rains, views sharpen with cooler, drier air, and the larch color begins in the higher surrounding drainages. October visits can encounter early snow on the summit but the scramble remains accessible most years through mid-October.
November through May: The access road is typically closed or impassable due to snow and mud. The summit itself holds snow well into June.
What to Bring
- Water (2+ liters per person): There's no water source on this trail. The entire climb is exposed enough that you'll be sweating through it in summer.
- Trekking poles: The steep grade makes them useful on the way up and valuable on the descent.
- Sturdy hiking boots: The summit scramble involves uneven volcanic rock. Trail runners work for confident scramblers; ankle support helps if you're less comfortable on rock.
- Layers and wind shell: The summit at 4,907 feet gets cold fast when clouds or wind move in. Carry something warm even in July.
- Sunscreen: The upper half of the trail and the summit get full sun. At elevation, you burn faster than you expect.
- Snacks: The climb is short but intense. A good meal at the summit rewards the effort.
Trailhead Access
The trail is accessed from Trout Lake, WA, which has a small general store, gas, and limited food options. Fill up on supplies before heading up Forest Road 8810. There are no services past Trout Lake in this direction.
The nearest developed campground is Peterson Prairie Campground, about 8 miles from Trout Lake on WA-141. It has 30 sites available for reservation through Recreation.gov. Primitive camping is also possible on dispersed sites along the forest road network east of Trout Lake, subject to standard Forest Service rules (no camping within 200 feet of water, no campfires during fire restrictions).
Sleeping Beauty makes a natural pairing with a day in the Mt. Adams area. The Mount Adams Wilderness is immediately to the north, and the Trout Lake area has several other hiking options for a weekend trip based out of the valley. The Indian Heaven Wilderness Loop, about 20 miles west near the Cultus Creek Campground, is the ideal complement: Sleeping Beauty gives you the summit views, while Indian Heaven shows you the gentler lake-dotted plateau of the same volcanic landscape.

If you're also spending time on the Oregon side of the Columbia, Mt. Hood National Forest is about an hour's drive south and offers a different set of summit and waterfall trails.
