How to get there
For Forest Road 2355, drive north from Shelton on Highway 101 about 12 miles, then take Skokomish Valley Road west to Forest Road 23. Follow Forest Road 23 northwest, take the right fork toward Lebar Horse Camp onto Forest Road 2353, and stay left at the junction with Forest Road 2355. For Forest Road 2451-100, take Lake Cushman Road (SR-119) northwest from Hoodsport to Forest Road 24 at Big Creek Campground. Go west on Forest Road 24 toward Olympic National Park, turn left onto Forest Road 2451 before reaching the park, and follow it to the 2451-100 spur. Check directions, conditions, and closures with the Hood Canal Ranger District office in Quilcene at (360) 765-2200.
- Forest Road 2355
A principal road approach reached from Shelton via Skokomish Valley Road and Forest Roads 23 and 2353. Upper portions require a high-clearance vehicle. Seasonal closure runs from October 1 to May 1 to protect wildlife. Access beyond the road is cross-country, not by constructed trail.
- Forest Road 2451-100
A principal road approach reached from Hoodsport via Lake Cushman Road and Forest Roads 24 and 2451. Upper portions require a high-clearance vehicle. Seasonal closure runs from October 1 to May 1 to protect wildlife. Confirm current conditions before attempting this approach; there is no constructed trail into the wilderness.

Small wilderness, rugged terrain
Wonder Mountain Wilderness occupies 2,349 acres west of Lake Cushman in Mason County, Washington, bordering Olympic National Park. It is one of the smallest wilderness areas in the western United States, but its compact boundary holds substantial relief: elevations rise from 1,740 feet in McKay Creek to 4,758 feet on Wonder Mountain. Dense Douglas-fir, western hemlock, and Pacific silver fir cover the lower slopes. Higher ground breaks into massive rock outcrops and precipitous pinnacles. Wonder Ponds and other small ponds sit in the high headwaters of McKay Creek; there are no rivers or major streams within the wilderness. The landscape offers primitive backpacking, camping, fishing, and mountain climbing, with excellent opportunities for solitude. Its small size should not be mistaken for easy access or straightforward travel.
Cross-country travel, not trail hiking
There are no constructed trails within Wonder Mountain Wilderness, and no trails lead to its boundaries. Every outing requires cross-country route finding rather than following a maintained tread. Steep forested slopes, exposed ridges, and tangles of huckleberry and thimbleberry make movement demanding; alder, willow, and vine maple thicken the creek corridors. Carry a map and compass and know how to use them before leaving the road. Plan around terrain and navigation rather than assuming a normal trail-hiking pace. Wonder Mountain and Wonder Ponds are possible objectives, not destinations connected by established hiking routes. Rain gear, adequate clothing, food, and backpacking equipment are essential. Precipitation can be substantial and often falls as snow, so road access alone does not establish that upper slopes are suitable for a particular trip.
Seasonal access and primitive camping
Forest Road 2355 and Forest Road 2451-100 provide the two principal road approaches. Both require high-clearance vehicles on their upper portions, and both have seasonal closures from October 1 to May 1 to protect wildlife. Confirm directions, road conditions, and any additional closures with the Hood Canal Ranger District office in Quilcene before departure. Once inside the wilderness, use Leave No Trace practices and plan for primitive camping rather than developed facilities. Fires and wood gathering are prohibited above 3,500 feet. Fires are also prohibited at Wonder Ponds and every other pond in the wilderness; use a stove instead. Groups may not exceed 12 people or eight head of livestock. Equipment, personal property, and supplies may not be left unattended for more than 24 hours. Confirm any permit requirements with Olympic National Forest.

Route options
- Wonder Mountain cross-country objectiveDifficult cross-country mountain travel
Wonder Mountain is the wilderness high point. Treat it as a self-planned mountain objective, not an established summit route. The surrounding terrain includes steep forested slopes, exposed ridges, massive rock outcrops, and precipitous pinnacles. Navigation skills and terrain assessment are central to planning.
- Wonder Ponds cross-country objectiveDifficult cross-country travel
The ponds in the high headwaters of McKay Creek offer an objective for self-planned cross-country travel or primitive backpacking. No constructed trail reaches them, and forest and brush complicate travel. Fires are prohibited at Wonder Ponds and all other ponds in the wilderness; use a stove.
Sample itineraries
- Cross-country day exploration · 1 day
For experienced off-trail travelers, plan a conservative outing on Wonder Mountain Wilderness’s forested lower slopes. Confirm access via Forest Road 2355 or Forest Road 2451-100 before leaving. Navigate with map and compass, allow extra time for dense vegetation, and turn back before terrain exceeds the group’s abilities.
- Wonder Ponds overnight · 2 days
Plan a self-navigated backpack toward Wonder Ponds in the high headwaters of McKay Creek. This is a cross-country objective, not an established route. Allow substantial time for steep slopes and brush, select a low-impact camping location, and use a stove: fires are prohibited at every pond.
Seasonal conditions
Spring
Spring; access-road closures extend to May 1
Snow and wet ground can complicate cross-country travel. Both major access roads have seasonal wildlife closures from October 1 to May 1. Confirm road status and upper-elevation conditions with the Hood Canal Ranger District before planning access.
Summer
Summer
Summer temperatures seldom exceed 80 degrees Fahrenheit, but rain protection remains essential. Dense brush, steep forested slopes, and exposed ridges make travel demanding even in favorable weather. Upper portions of both access roads require high-clearance vehicles.
Fall
Fall; seasonal access-road closures begin October 1
Prepare for wet weather and possible snow in this precipitation-heavy wilderness. Both major access roads close seasonally to protect wildlife beginning October 1. Check current conditions rather than assuming an early-fall trip has reliable vehicle access.
Winter
Winter; within the October 1–May 1 access-road closure period
Precipitation often falls as snow. Trail-free terrain, steep slopes, and exposed ridges make winter navigation particularly demanding. Seasonal closures restrict vehicle access on both major approach roads; confirm conditions and access with the ranger district.
