Dolason Prairie Trail

Brown grass waves on a hillside. Forets cover the hills on the far side of the valley.

This is a 10-mile lung-buster that drops 2,500 feet from high Bald Hills meadows into the deep river valley of Redwood and Emerald Creeks, then demands you climb every foot back out. You'll pass a historic 19th-century barn and see the stark contrast between old-growth redwood groves and surrounding second-growth forests. This is serious terrain for fit hikers only—cell service fails, rescue is slow, and you've got to know your limits.

Trailhead & access

Trailhead Location: Bald Hills Road
Shuttle Required: 0

Permits & conditions

Permit Details: No permit required.
Fees: No entrance fee. America the Beautiful annual pass ($80) accepted.

Seasonal Closures: Trails remain open year-round. Winter mud and storms can make the route hazardous; most hikers visit June–September.

Facilities & rules

Restrooms At Trailhead: 1
Water Sources: Filter at Redwood Creek and Emerald Creek mid-trail. Start with full containers—the initial climb offers no water.
Accessibility: Rooty, steep, and muddy in spots. Not accessible to those with mobility limitations. Requires strong legs and confidence on steep descents.

Safety & strategy

Hazards: Steep descent and re-ascent
Loose footing on exposed slopes
Black bears in area
Limited to no cell coverage
Fog and low visibility in off-season
Creek crossings (slippery)
Hazard Details: The 2,500-foot descent is unforgiving—one slip and you're sliding. Bears are confirmed in the area; maintain 100-yard distance. Cell coverage fails completely; you're on your own for rescue. Creek crossings are slippery when wet. Fog obscures the trail and views, especially October–May.
Cell Service: false
Crowd Level: Light to moderate
Peak Crowd Times: Weekends and July–August see higher traffic, but this remote, strenuous route keeps casual hikers away.
Best Season: Late spring to early fall (June–September)
Best Time To Visit: Start by 6:00 AM to maximize daylight. Best June–September when weather is most stable. Avoid fog which obscures views and increases disorientation risk.
Tips Advice: Carry minimum 2–3 liters of water; filter at creek sources.
Tighten your boots—the descent is relentless and loose ground is common.
Use a detailed map and trail guide; don't rely on phone GPS.
Make noise constantly for bears.
Stay on marked trail; off-trail creates erosion and gets hikers lost.
Pets prohibited—it's law.
Check weather before you go; afternoon thunderstorms are possible.

More details

Park Area: Bald Hills, Redwood National and State Parks
Trail Markers: Well-worn trail with basic blazes, but bring a map. NPS recommends a detailed trail guide; online maps are unreliable here.
Dogs Allowed: false
Biking Allowed: false
Shade Level: Mixed. High prairie is sun-exposed; redwood valleys provide dense shade.
Emergency Contacts: No cell coverage. Inform someone of your trip plan and expected return time. Contact park headquarters at https://www.nps.gov/redw/index.htm for pre-trip details.
Map Recommended: 1
Snow Dates: Rare. Snow is uncommon at this coastal elevation.
Mud Season: November–April after heavy rains. Drainage is poor on steep sections.
Fall Colors Peak: Not applicable. Redwoods don't provide dramatic fall color.
Bug Season: June–September. Coastal mosquitoes peak in July–August.
Insider Tips: The descent into the valley is steeper than you expect—don't judge difficulty by the first mile.
The false summit at Mile 6 will fool you; the real payoff is the Redwood Creek overlook 0.5 miles further.
Bring trekking poles; they save your knees on the re-ascent.
Start early and finish before dark; headlamps are mandatory backup.
The historic barn is protected; look, don't disturb it.
Family Friendly Notes: Not suitable for young children. The 10-mile distance, 5,000-foot elevation change, and steep drop-offs exceed most family comfort. Teenagers (14+) who are fit and experienced hikers can manage it with parental supervision and strict trail discipline.
Nearby Facilities: Trailhead has parking, picnic table, vault toilet. Nearest park visitor facilities unknown; nearest town services likely 25+ miles away.
Review Summary: Hikers report this is a serious physical challenge. Most say the 2,500-foot descent is harder on the knees than expected on the re-ascent. The contrast between old-growth and logged forests, plus the remoteness, draws experienced hikers back.

Location

Frequently asked questions

Is 10 miles too far for me?

Honest answer: distance is secondary here—the 5,000 feet of elevation is the real test. If you can climb 5,000 feet in a day without stopping constantly, the mileage is doable. Fit hikers finish in 6–8 hours. If uncertain, train on a 3,000-foot climb first.

Can I hike this alone?

Legally yes. Safely? Only if you're experienced and tell someone your plan with a firm check-in time. Cell coverage fails completely. A twisted ankle on the descent means you're walking out yourself or waiting hours for rescue.

What kind of water filter do I need?

A portable pump filter or squeeze filter for streams. Giardia is present in park waterways. Don't drink unfiltered creek water.

Will I see bears?

Unlikely if you're making noise. Keep a 100-yard distance if you do. Avoid strong-smelling foods. Bears typically avoid noisy hikers.

What if I get lost?

Stay on the trail—getting lost here is a problem because cell coverage fails. Bring a map and compass. Practice navigation before you go. The trail is generally well-worn, but mushroom picking can pull you off course.

Do I need trekking poles?

Not required, but highly recommended. Poles reduce knee stress on the 2,500-foot re-ascent by up to 25%. The descent is steep and poles help with balance on loose ground.
