Soda Peaks Lake Trail #133

The Soda Peaks Lake Trail #133 is an 8-km point-to-point trail in Washington State, United States, gaining approximately 817 m of elevation through the heart of the Trapper Creek Wilderness. Rated difficult, this Pacific Northwest classic leads through towering old-growth conifers to a breathtaking glacially carved cirque lake, with optional summit scrambles offering panoramic views of Mount St. Helens, Mount Rainier, and Mount Adams.

About the Soda Peaks Lake Trail #133

The Soda Peaks Lake Trail #133 cuts through the southwestern corner of the Trapper Creek Wilderness, one of the most intact old-growth forest reserves in the southern Washington Cascades. Managed by the US Forest Service within Gifford Pinchot National Forest, the trail runs 8 km as a point-to-point route, threading through ancient stands of Douglas fir, western red cedar, and western hemlock before climbing to Soda Peaks Lake — a glacially carved cirque nestled at around 1,250 m elevation.

The trail is officially classified as part of the Regional Walking Network (RWN), recognising its significance as a substantial regional route within the Gifford Pinchot corridor. The landscape around Trapper Creek Wilderness was shaped by glaciers during the last ice age, and Soda Peaks Lake is the most dramatic expression of that legacy: a cold, clear lake cupped in a steep rock bowl, ringed by conifers and fed by snowmelt well into summer.

With 817 m of cumulative elevation gain packed into 8 km, this is not a trail for beginners. The climb is sustained and often steep, involving multiple switchback sections through thick forest where the canopy closes overhead and the sounds of running water and birdsong replace all traces of the outside world. The reward is proportional to the effort. Soda Peaks Lake is strikingly beautiful, and hikers willing to scramble a maintained user trail up to East Soda Peak gain views of three major Cascade volcanoes simultaneously.

Trail #133 is a point-to-point route, meaning you either return the way you came or arrange a car shuttle between the two trailheads. Many hikers access the trail from the west via the Government Mineral Springs area off Forest Road 3065, combining Trail #132 (Trapper Creek Trail) with Trail #133 for a fuller wilderness experience.

Route Overview & Stages

The trail is typically walked west to east, starting near Government Mineral Springs and finishing at the eastern trailhead on Road 54. The first section is relatively gentle, following Trapper Creek upstream through old-growth forest before the route turns onto Trail #133 and begins its serious ascent to the saddle and lake. Most hikers complete the full route as a single day hike.

The total distance of 8 km and 817 m of gain translates to an average gradient of roughly 10% — but the distribution is heavily uneven. Stage 2 carries nearly 76% of the total climb, reaching gradients of 20–25% on the steepest switchback pitches. Stage 3 is a largely flat traverse to the lake, making it a welcome relief after the exertion of Stage 2.

Highlights & Points of Interest

• Government Mineral Springs — The historic starting area features a natural carbonated mineral water pump and the remnants of a 1930s resort complex. The spring water is drinkable and worth sampling before setting out; it has a distinctive effervescent quality unlike ordinary mountain springs.
• Trapper Creek Old-Growth Stand — Within the first 2 km, the trail enters a cathedral grove of Douglas fir trees estimated at 300–500 years old, with trunk diameters exceeding 2 m. This is among the finest old-growth stands accessible by maintained trail in the entire southern Washington Cascades.
• Trapper Creek Canyon — The lower trail hugs the canyon of Trapper Creek, a fast-moving stream cutting through basalt bedrock. The water runs clear and cold year-round, with small cascades and pools visible from the trail in several places during Stage 1.
• Trail #132 / #133 Creek Crossing — A converted vehicle bridge spans Trapper Creek at the junction where you leave Trail #132 and begin Trail #133. The bridge provides a dry crossing even in high-water spring conditions, and the confluence area is a reliable water stop before the steep climb begins.
• Switchback Corridor — The 3.5 km switchback section through Stage 2 is demanding but botanically rewarding. In late June and early July, avalanche lily, trillium, and bleeding heart bloom along the forest floor, and the upper switchbacks open occasionally to views of the surrounding ridges.
• Upper Saddle at 1,200 m — At the crest of Stage 2, the trail reaches a saddle forming the divide between the Trapper Creek and Wind River drainages. On clear days, the snow-capped cone of Mount St. Helens becomes visible here for the first time, framed between old-growth snags.
• Soda Peaks Lake — The centerpiece of the entire trail: a glacially carved cirque lake at approximately 1,250 m elevation, ringed by steep rock walls and dense conifers. The lake is calm and mirror-like on summer mornings, and swimming is possible in late August when water temperatures approach 15 °C.
• East Soda Peak — A user trail leads from the lake to the summit of East Soda Peak, adding roughly 400 m of climbing and 1.5–2 hours to the day. The panorama from the top spans Mount St. Helens (63 km northwest), Mount Rainier (90 km north), and Mount Adams (40 km east) — three major Cascade volcanoes visible simultaneously from a single vantage point.

Best Time to Hike the Soda Peaks Lake Trail #133

The trail is accessible from late June through October in a typical year, with persistent snowpack at upper elevations often blocking the saddle and lake until mid-summer. As of 2026, the US Forest Service typically opens the Forest Road 3065 access road by mid-June, though heavy snowpack winters can push that back to early July — always check current road status with the Mount Adams Ranger District before driving out.

July is the single best month to hike Soda Peaks Lake Trail #133. By mid-July the snow has cleared from the upper trail and the saddle, wildflowers are at peak bloom along the switchbacks, and Soda Peaks Lake fills to its highest and most photogenic level. Daytime temperatures at the trailhead hover around 20–24 °C, dropping to 8–12 °C at the lake by evening. July also offers the longest daylight hours, giving hikers ample time to explore East Soda Peak without rushing the descent.

August is an excellent alternative, with more settled weather patterns, slightly drier trail conditions underfoot, and the possibility of swimming in the lake. Trail traffic is at its seasonal peak in August, though the Trapper Creek Wilderness sees far fewer visitors than better-known Cascade destinations.

September brings fall colour to the vine maple and huckleberry along the lower trail, substantially fewer hikers, and reliably cool temperatures ideal for sustained climbing. Early September is particularly pleasant; afternoon showers become more frequent and prolonged after mid-month as the Pacific storm track reasserts itself.

October is the last viable month before the upper trail re-enters winter conditions. The forest puts on a strong colour display and the lake sits glassy and still under autumn light, but temperatures can drop below freezing overnight and sustained rain is likely. Check for early-season snowfall at the trailhead before committing to October dates.

Practical Information

Accommodation

There are no huts or maintained shelters on Trail #133. The wilderness designation of Trapper Creek prohibits permanent structures inside the boundary, so overnight stays mean backcountry camping. Dispersed camping is permitted throughout the wilderness with a free self-issued permit (see Permits & Fees). The most popular sites are located within 100 m of the north shore of Soda Peaks Lake, where flat ground exists among the conifers; several creek-side clearings along Stage 1 also serve as good camping spots. Pack out all waste under Leave No Trace principles. Campfires are subject to seasonal restrictions and are typically banned throughout the Gifford Pinchot backcountry from July through September.

For hikers preferring established facilities, the nearest campground is Paradise Creek Campground on Forest Road 30, approximately 20 km east of the western trailhead, with sites at roughly $18–22 USD per night (approximately €16–20). The town of White Salmon, WA, around 40 km southeast, offers motels and vacation rentals typically priced at $90–150 USD per night (€82–137). The Columbia River Gorge area around Hood River, Oregon (50 km south) provides the widest range of lodging options including bed-and-breakfasts, boutique hotels, and short-term rentals.

Getting There & Back

The western trailhead at Government Mineral Springs is located off Forest Road 3065, reached via State Highway 14 eastbound from the Vancouver, WA area, then north on Wind River Road from the town of Carson, WA. From Portland, Oregon (approximately 60 km south), the drive takes around 1 hour 20 minutes. From Seattle (approximately 260 km north), allow 3 hours 30 minutes depending on traffic through the I-5 corridor.

The nearest commercial airport is Portland International Airport (PDX), 75 km south of the trailhead. Rental cars are available at PDX from all major providers; drive north across the Columbia River on I-205, then east on Highway 14 to Carson, then north on Wind River Road. There is no public transport serving the trailhead area — a private or rental vehicle is essential for access.

For the full point-to-point experience, the eastern trailhead is located on Forest Road 54, approximately 18 km by road from the western trailhead. A two-car shuttle is the cleanest arrangement. Alternatively, hiking out-and-back from either trailhead doubles the distance to approximately 16 km total. The Washington Trails Association trip report page carries recent hiker-submitted condition updates, road closures, and bridge status — checking it within 48 hours of your planned departure is strongly recommended.

Permits & Fees

A Northwest Forest Pass is required to park at the Government Mineral Springs trailhead. The pass costs $5 USD (approximately €4.60) per day or $30 USD (€27.50) for an annual pass, available online through Recreation.gov, at local ranger stations, and at some outdoor retailers. The interagency America the Beautiful Annual Pass at $80 USD (€73) covers parking at all federal recreation sites and is worthwhile if you plan multiple visits to National Forests or National Parks in a year.

A Trapper Creek Wilderness self-registration permit is required for all overnight stays in the wilderness. These permits are free and self-issued from the registration box at the trailhead — no advance booking is needed under the current system. Day hikers do not require a wilderness permit. No quota system is currently in place for Trapper Creek Wilderness, meaning permits remain available without reservation, though this can change; confirm with the Mount Adams Ranger District (Gifford Pinchot National Forest) before your trip.

Gear & Packing List

The sustained 817 m climb on Trail #133 puts a premium on a light, well-fitted pack. For a day hike, a 20–28 L pack is ideal; for an overnight at the lake, look at packs in the 35–50 L range with good hip-belt load transfer for the steep Stage 2 ascent. The Hyperlite Mountain Gear 2400 Windrider is an excellent choice for fast-and-light day hikers: at under 500 g it adds almost nothing to your base weight, and the Dyneema Composite Fabric shell sheds Pacific Northwest rain reliably. For overnight trips, the Osprey Aether 65 offers outstanding load transfer on sustained climbs and carries a 2-night kit comfortably. If you prefer a mid-range volume option that bridges both use cases, the Deuter Aircontact Lite 45+10 delivers excellent hip-belt stability and an adjustable back length that works well on steep Cascade switchbacks.

Key items to pack regardless of pack choice:

• Navigation — Download offline maps via Caltopo or Gaia GPS before leaving; there is zero cell coverage inside the Trapper Creek Wilderness. Carry a paper topo map of the Trapper Creek Wilderness USGS quad as backup.
• Water filter — Trapper Creek and several side streams provide abundant water sources, but giardia and cryptosporidium are present throughout the Cascades. A lightweight squeeze filter or UV pen is non-negotiable.
• Layering system — Even in July, the saddle and lake are significantly cooler than the valley floor. A packable insulated jacket and waterproof hard shell are essential; afternoon thunderstorms are possible in summer and move in quickly from the southwest.
• Trekking poles — The steep switchback descent in Stage 2 is hard on the knees. Poles reduce impact load by an estimated 25% per step and are particularly valuable on the loose trail surface after rain.
• Food and snacks — With 817 m of gain, caloric demand is high. Budget 400–500 kcal per hour of active hiking; our guide on how many calories you need hiking a full day has detailed calculations by body weight and terrain. Energy-dense trail mix, bars, and nut butter sachets are the most weight-efficient options.
• Headlamp — If you plan to visit East Soda Peak or linger at the lake, a headlamp ensures a safe descent after sunset. Sunset in the Gifford Pinchot in July is around 21:00 Pacific Time.
• Bear canister or hang kit — Black bears are active throughout the Trapper Creek Wilderness. Secure all food, cookware, and scented items when camping.
• Sun protection — The upper saddle and East Soda Peak scramble are fully exposed. SPF 50 sunscreen, sunglasses, and a hat are necessary even on partly cloudy days at elevation.
