Sunshine Primitive Trail #198

The Sunshine Primitive Trail #198 is a 3-kilometre point-to-point trail in the Trapper Creek Wilderness of Gifford Pinchot National Forest, Washington, United States, gaining 488 m of elevation over its steep connector route. Rated moderate to strenuous, it links the Trapper Creek Trail (#192.2) to the Observation Trail (#132), delivering old-growth forest solitude and sweeping Cascade ridge views on one of Washington's most rewarding wilderness connectors.

About the Sunshine Primitive Trail #198

The Sunshine Primitive Trail #198 cuts through the heart of Trapper Creek Wilderness, a 6,050-acre designated wilderness area in Gifford Pinchot National Forest in the southern Washington Cascades. The trail serves as the critical connector between the Trapper Creek Trail (#192.2) at the valley floor and the Observation Trail (#132) along the upper ridge, making it the linchpin of a popular wilderness loop that takes in some of the finest old-growth forest in the Pacific Northwest.

At 3 kilometres with 488 metres of elevation gain, the Sunshine Trail earns its primitive designation. The US Forest Service deliberately leaves fallen logs across the tread to maintain the wilderness character, and the route demands consistent navigation skills—especially in the dense sections where the path can become indistinct. This is not a trail to rush; experienced hikers who take time to read the terrain find the rewards well worth the effort.

The surrounding Trapper Creek Wilderness protects a remarkable stand of Douglas-fir, western red cedar, and western hemlock, with Trapper Creek itself cutting a clear-water channel through the valley below. The trail also intersects the Rim Primitive Trail (#202) approximately 0.5 kilometres beyond its junction with the Observation Trail, opening further loop options for multi-day parties.

One critical planning note: the 2020 Big Hollow Fire burned through almost the entire length of the Sunshine Trail, leaving sections where the tread disappears entirely. The Gifford Pinchot National Forest continues to monitor and maintain the route, while volunteer crews from the Washington Trails Association have conducted maintenance work in the years following the fire. As of 2026, recovery is progressing but current-season condition reports are essential reading before you set off.

The Sunshine Trail is part of the Regional Walking Network (RWN) and sits within the Mount Adams Ranger District, managed by the US Forest Service. Primary access is via the Government Mineral Springs Trailhead, reached from the town of Carson on the Columbia River, approximately 1.5 hours east of Portland, Oregon.

Route Overview & Stages

The Sunshine Trail runs point-to-point from its lower junction with the Trapper Creek Trail (#192.2) to its upper junction with the Observation Trail (#132), climbing steeply through two distinct terrain zones. Most hikers approach from the Government Mineral Springs Trailhead and complete the Sunshine Trail as part of a wider loop. The trail gains 488 m over 3 km—an average gradient of over 16%, with the steepest pitches concentrated in the lower half where the route leaves the valley floor and enters the burn zone.

Total: 3 km · 488 m elevation gain · Highest point: 1,037 m (3,400 ft)

Highlights & Points of Interest

• Government Mineral Springs Trailhead (642 m): The primary access point for Trapper Creek Wilderness, with a self-issue wilderness permit station, vault toilets, and parking for approximately 30 vehicles. The mineral springs at this site once attracted health-seekers in the early 1900s; interpretive signs near the parking area tell the story.
• Trapper Creek Valley Old-Growth: The lower approach via Trail #192 follows Trapper Creek through some of the most impressive old-growth western red cedar and Douglas-fir in Gifford Pinchot National Forest, with trees exceeding 400 years of age and trunk diameters over 2 metres. The canopy is cathedral-like and provides welcome shade on warm summer days.
• Sunshine Creek Crossing: A small but clear tributary crossed at approximately the 0.8 km mark. Water flow is reliable through early summer but can diminish by late August; treat all backcountry water before drinking.
• Big Hollow Fire Ghost Forest: The 2020 Big Hollow Fire burned through significant portions of the upper trail, leaving a dramatic landscape of standing snags, fireweed meadows, and early conifer regeneration. Visually striking and ecologically important—move efficiently through on windy days when snag falls are a hazard.
• Sunshine Ridge Viewpoint (~950 m): A gap in the recovering canopy at roughly the 1.5 km mark provides views east toward Mount Adams (3,742 m), one of the most distinctive volcanic peaks in the Cascades, and southeast toward the Columbia River Gorge on clear days.
• Observation Trail #132 Junction: At the upper end of the Sunshine Trail, this intersection opens the route to Observation Peak and the full ridgeline traverse. Strong hikers can extend the day considerably here for sweeping Cascade panoramas.
• Rim Primitive Trail #202 Junction: Located approximately 0.5 km beyond the Observation Trail junction, this intersection enables the complete Trapper Creek Wilderness loop and is a critical navigation waypoint for multi-day itineraries.
• Trapper Creek Wilderness Interior: Inside the wilderness boundary, deadfall is left in place, trails are maintained to primitive standards, and no mechanised equipment is permitted. This creates a genuinely remote atmosphere unusual for a wilderness area just 100 km from Portland.

Best Time to Hike the Sunshine Primitive Trail #198

The Sunshine Trail sits between 640 m and 1,037 m elevation in the maritime-influenced western Cascades of Washington. Snow typically covers the upper sections from November through late June, and the post-fire terrain means the ground stays wetter for longer than the old-growth canopy once permitted.

July sees snowpack retreating rapidly, wildflowers appearing in the burn zones, and creeks running strong. Trail conditions on north-facing slopes can still be muddy, and route-finding challenges in the burn zone are compounded by saturated ground. August is the single best month to hike the Sunshine Primitive Trail #198: Pacific Northwest skies are reliably clear, temperatures at the 1,037 m highpoint hover between 15–22 °C, creek crossings are at their safest and shallowest, and the fireweed bloom in the burn areas reaches spectacular peak. September brings golden light, far fewer hikers, and early autumn colour in the deciduous understorey—though morning temperatures at elevation drop to 4–6 °C and early snowfall is possible from mid-month onward.

As of 2026, trail conditions in the upper section remain affected by Big Hollow Fire blowdown. Check the Gifford Pinchot National Forest website for current condition alerts before your trip, particularly after winter storm seasons when snag falls can block the primitive route.

Months to avoid: October through June on the upper trail due to snowpack and post-fire instability. Spring in particular brings elevated risk of falling snags in windy conditions within the burn zone.

Practical Information

Accommodation

The Sunshine Trail is a 3 km connector best experienced as part of the full Trapper Creek Wilderness loop covering Trails #192, #198, and #132—approximately 16–18 km total. Most hikers tackle this as a 2-day backpacking trip with one wilderness overnight.

Dispersed wilderness camping is free throughout Trapper Creek Wilderness with a self-issued permit. Popular overnight spots lie along the Trapper Creek valley at approximately 4–5 km from the trailhead via Trail #192, with flat ground near the creek and reliable water year-round. Campfires are permitted below 1,000 m in non-fire-restricted periods, but a lightweight stove is strongly recommended given frequent summer fire bans.

Government Mineral Springs Campground sits adjacent to the trailhead and offers basic drive-in sites for approximately $18–22 USD (€17–20) per night. Book via recreation.gov during peak season, as sites fill quickly on summer weekends.

The nearest indoor accommodation is in Carson, Washington, approximately 25 km south on Wind River Highway. Carson Hot Springs Resort offers rooms from around $120–160 USD (€110–150) per night and is a favourite post-hike recovery stop for Trapper Creek regulars.

Getting There & Back

The Government Mineral Springs Trailhead is located approximately 40 km north of Carson, Washington, along Wind River Highway (WA-30):

• From Portland, OR: Drive east on I-84 / US-14 to Carson (~80 km, 1 hour), then north on Wind River Highway for 15 km, then east on NF-64 to Government Mineral Springs. Total: ~100 km, approximately 1 hour 30 minutes.
• From Vancouver, WA: Take WA-14 east to Carson (~80 km, 1 hour), then the same route north. Approximately 1 hour 30 minutes total.
• From Seattle, WA: Drive south on I-5, then east on US-14 past White Salmon to Carson. Total: ~260 km, approximately 3 hours.
• Nearest airport: Portland International Airport (PDX), approximately 100 km southwest. Car hire is essential—there is no public transport to the trailhead.

Most hikers complete the full loop returning to the Government Mineral Springs Trailhead, avoiding any need for a two-car shuttle. Point-to-point hikers can arrange shuttles via outdoor communities in Carson or Vancouver, WA.

Permits & Fees

• Wilderness Permit: Required for all overnight stays in Trapper Creek Wilderness. Free and self-issued at the trailhead permit station; carry it throughout your trip.
• Recreation Pass: A Northwest Forest Pass ($30 USD / €28 annually) or America the Beautiful Pass ($80 USD / €74 annually) is required for parking at Government Mineral Springs Trailhead. Day passes are available for $5 USD (€5) at the trailhead.
• Campfire Restrictions: Fire bans are frequently in effect July–September during dry years. Fines for violations in wilderness areas can exceed $500 USD; check current restrictions on the Gifford Pinchot National Forest website before departure.
• No quota system: As of 2026, no permit quota or advance reservation is required for Trapper Creek Wilderness, making this a more accessible option compared to many oversubscribed Pacific Northwest wildernesses.

Gear & Packing List

The Sunshine Primitive Trail's steep gradient, primitive tread, and post-fire route-finding demand a thoughtful pack. For hikers tackling the Sunshine connector as part of a full Trapper Creek day loop (~16 km total), a 12–28 litre pack suits most. For the 2-day backpacking loop requiring overnight camping gear, a 45–55 litre pack is appropriate. Our Best Ultralight Backpacks 2026 guide reviews the top options across both categories.

Recommended packs:

• Salomon ADV Skin 12 — ideal for fast day hikers tackling the Sunshine connector; the vest-style fit keeps weight close and breathing easy on steep pitches
• Salomon ADV Skin 20 — a step up for hikers carrying extra layers, a water filter, and a full day's food on the 16 km loop
• Hyperlite Mountain Gear Aero 28 — ultralight and fully waterproof; outstanding for Pacific Northwest conditions where rain gear and insulation layers add significant weight fast
• Zpacks Arc Haul Ultra 50L — for overnight loops through Trapper Creek Wilderness requiring shelter, a sleeping system, two days of food, and bear-aware storage

Essential items for the Sunshine Primitive Trail:

• Navigation: USGS topo map and compass; GPS cell coverage is unreliable in the valley and burn zone, and the primitive tread in fire-affected sections requires careful map reading to stay on route.
• Footwear: Waterproof trail runners or low hiking boots with aggressive tread for steep, log-strewn sections and the Sunshine Creek crossing.
• Insulation and waterproofs: A down or synthetic insulation layer and waterproof shell are non-negotiable in the Pacific Northwest; the ridge sits at 1,037 m and afternoon temperatures can drop sharply with incoming weather.
• Water treatment: A lightweight filter or chemical tablets; Sunshine Creek provides reliable water through summer but treat all backcountry sources.
• Sun protection: The burn zone sections offer zero canopy shade—sunscreen, a hat, and sunglasses are essential on August hikes.
• First-aid kit: Include blister treatment and a SAM splint; limited cell coverage and remote terrain mean emergency services response times are long.
