Killen Creek Trail #113

The Killen Creek Trail #113 is a 5-km point-to-point trail in the Mt. Adams Wilderness of Washington, United States, gaining 701 m of elevation from lodgepole pine forest to the Pacific Crest Trail junction at 1,830 m. Rated hard, it threads through open subalpine meadows brilliant with lupine and paintbrush in summer and delivers unobstructed views of Mt. Adams and its glacier-draped 3,743-m summit.

About the Killen Creek Trail #113

Tucked into the northern flank of the Mt. Adams Wilderness within Gifford Pinchot National Forest, Killen Creek Trail #113 carries one of the richest histories of any path on Washington's second-highest volcano. For generations before it became a designated hiking route, local berry-pickers followed these slopes each summer to harvest huckleberries, and Basque sheepherders drove their flocks up to the high meadows for seasonal pasture. The ruined outline of a sheepherder's cabin, still visible about 3.2 km into the trail, is a quiet reminder of that working mountain landscape.

Today the trail attracts hikers, naturalists, and peak-baggers drawn by two things: the wildflowers and the volcano. From the moment the lodgepole pines thin out — around the 2 km mark — the path enters a succession of subalpine meadows that explode with colour between July and mid-August. Lupine carpets the open slopes in purple; Indian paintbrush spikes of red and orange follow close behind; aster and phlox complete the palette in the rockier upper reaches. Above the flowers, Mt. Adams fills the entire southern skyline, with the Adams Glacier's blue-white ice clearly visible from the trail's upper section.

The trail ends where it meets the Pacific Crest Trail (PCT) at roughly 1,830 m, after 5 km and 701 m of ascent. The junction sits at the edge of an open rocky ridge, and an optional 1.9 km extension along the PCT northeast leads to the Killen Creek Meadows basin — among the finest wildflower viewpoints on the entire Mt. Adams circuit. Most day hikers reach the PCT junction, rest at the ridge-top, then retrace their steps. The trail is managed by the U.S. Forest Service and lies entirely within the Mt. Adams Wilderness, where Leave No Trace and wilderness regulations apply throughout.

Route Overview & Stages

Killen Creek Trail #113 climbs from the trailhead on Forest Road 2329 to the PCT junction with no significant forks along the way. The ascent is consistent throughout — there is no flat reprieve — which earns the trail its hard rating despite its modest 5 km distance. Below is a stage breakdown based on terrain and key landmarks.

Hikers wanting extra mileage can continue 1.9 km northeast along the PCT to Killen Creek Meadows, a broad wildflower basin with an elevated view of Mt. Adams and the Adams Glacier. Ascending further to High Camp adds a challenging scramble on loose volcanic rock and glacier-adjacent terrain that demands mountaineering experience and crampons — do not attempt the glacier itself without proper equipment and training.

Highlights & Points of Interest

• Killen Creek Trailhead (1,402 m): The signed trailhead on FR 2329 has a trail register and a pit toilet. The Killen Creek drainage runs close to the path for the first kilometre and offers reliable water in early season for filtering.
• Lodgepole Pine Forest (0–2 km): The opening kilometres wind through a classic Cascade dry-forest understory of lodgepole pine and Pacific silver fir. Pockets of huckleberry — one of the original berry-picking species used by Indigenous and early settler communities — line the trail margins.
• East Fork Adams Creek (~2.5 km): This seasonal stream runs strong with snowmelt through July. The crossing is typically achievable on stepping stones by late July but can be knee-deep in early season. It marks the last reliable water source before the PCT junction, so fill up here.
• Sheepherder Cabin Site (~3.2 km): The low foundation walls of a Basque sheepherder's cabin are visible just off the main trail. This site connects Killen Creek to a century of transhumance on Mt. Adams and makes a compelling rest stop with the first good views of the summit to the south.
• Subalpine Wildflower Meadows (3.5–5 km): The trail opens completely into rolling meadows. At peak season — late July to mid-August — lupine, Indian paintbrush, aster, and heather create vivid swaths of colour against volcanic grey soil. These meadows are among the finest on Washington's high routes.
• Mt. Adams Summit View (upper trail): Mt. Adams (3,743 m), Washington's second-highest peak, dominates the southern skyline from the upper meadows. The Adams Glacier and its visible crevasses are clearly distinguishable without binoculars on clear mornings.
• PCT Junction (1,830 m): The trail terminates at the Pacific Crest Trail, the 4,265-km spine of the American West Coast. The junction sits on an airy ridgeline with 270-degree views encompassing Mt. Rainier to the north on clear days.
• Killen Creek Meadows (optional, +1.9 km on PCT): Continuing northeast along the PCT leads to a broad meadow basin rated by the Washington Trails Association as one of the finest wildflower destinations on the entire Mt. Adams circuit — worth every extra step.

Best Time to Hike the Killen Creek Trail #113

The trail is accessible roughly from early July to mid-October, though the window shifts year to year depending on winter snowpack. As of 2026, the Gifford Pinchot National Forest reports that above-average spring snowfall in the South Cascades has pushed full upper-trail clearance to late July in some recent years — always check current conditions with the Randle Ranger District before heading out.

July brings the first wildflowers and cool temperatures, but creek crossings are at their highest and lingering snowfields can obscure the upper trail. Navigation experience is useful in the first half of the month. This period suits adventurous hikers comfortable with wet feet and route-finding.

August is the single best month to hike Killen Creek Trail #113. Wildflowers are at peak bloom across the subalpine meadows, the trail is typically snow-free to the PCT junction, and Mt. Adams stands in sharp relief on most mornings before afternoon clouds build. Temperatures at the trailhead average 18–23 °C by day; the upper meadows run 5–8 °C cooler. Afternoon thunderstorms are common above tree line after 14:00 — plan to start by 07:00 to be off the exposed upper ridge before weather develops.

September offers fewer crowds and the first autumn colours on the huckleberry shrubs — a genuinely beautiful alternative. Nights drop below freezing above 1,800 m from mid-September, so carry appropriate insulation for any wilderness camping. Days remain pleasant and the light is exceptional for photography.

October brings early snow to the upper trail and the PCT junction may be buried again by mid-month. Only attempt October hiking with microspikes, trekking poles, and strong route-finding skills. Check road conditions for FR 2329, which can close after the first significant snowfall.

Practical Information

Accommodation

There are no huts or hostels on or near Killen Creek Trail #113. Overnight options range from dispersed wilderness camping to developed campgrounds a short drive away.

• Dispersed Wilderness Camping (free): Camping is permitted throughout Mt. Adams Wilderness under Leave No Trace principles. Pitch at least 60 m from the trail, water sources, and other groups. No campfire rings exist in the meadow zones above 1,372 m — carry a stove. A free self-issued wilderness permit is required at the trailhead register.
• Takhlakh Lake Campground (~$20/night, ≈ €18): A developed USFS campground approximately 7 km from the trailhead on FR 2329. Sites have picnic tables and vault toilets. No electrical hook-ups available. Reservations through Recreation.gov are strongly recommended for summer weekends — book 2–3 weeks ahead.
• Randle, WA (motels, ~$90–130/night, ≈ €82–119): The nearest town with indoor lodging, roughly 48 km north. Budget motels and a small inn are available along the main strip; the town has a grocery store and fuel station useful for pre-trip resupply.

Getting There & Back

The Killen Creek Trailhead sits at the end of a gravel forest road with no public transport connection. A personal vehicle is essential.

• From Portland International Airport (PDX): Approximately 225 km and 3 hours by car. Take I-205 north across the Columbia River, then WA-14 east to White Salmon, north on WA-141 through Trout Lake, then Forest Roads 23 and 2329 to the trailhead. PDX is the closest international airport with major airline connections.
• From Randle, WA: Head south on FR 25 for 1.6 km, bear left onto FR 23 for 51 km, then turn left on FR 2329 and continue 7 km to the trailhead. Allow approximately 1 hour on gravel roads.
• From Trout Lake, WA: Head north on FR 23 for approximately 39 km, turn left on FR 2329, and continue 7 km. Allow ~55 minutes total.
• Road condition: FR 2329 is an unpaved gravel road passable by standard 2WD vehicles in good summer conditions. High-clearance is helpful but not strictly required. The road is typically gated from November through May or June — confirm access dates with the Randle Ranger District before planning an early-season trip.

Most hikers return to the trailhead on the same path. A one-way traverse linking to the PCT trailhead on FR 521 is possible with a two-vehicle shuttle, adding flexibility for strong hikers wanting to continue south along the PCT.

Permits & Fees

• Northwest Forest Pass — required for parking: $5/day (≈ €4.60) or $30/year (≈ €27.50). Available at the Randle Ranger Station, the Trout Lake Work Center, and online via Recreation.gov. An America the Beautiful Interagency Annual Pass ($80, ≈ €73) also covers this fee and is good value for anyone planning multiple national forest or national park visits.
• Mt. Adams Wilderness Permit — free: Self-issued at the trailhead register. Record your name, group size, intended route, and any overnight dates. No advance reservation or quota currently applies to the Killen Creek corridor, but wilderness permit systems can change — verify with the Gifford Pinchot National Forest before your trip.
• Campfire restrictions: Fires are prohibited above 4,500 ft (1,372 m) in the Mt. Adams Wilderness in all seasons. This ban covers the upper section of Killen Creek Trail and all designated wilderness campsites near the PCT junction. Always verify current fire restrictions, which may be tightened during drought conditions.

Gear & Packing List

Killen Creek Trail #113 is a hard day hike or light overnight in a true wilderness environment. The upper trail is fully exposed above tree line with no shelter from weather or sun. Pack with care even in midsummer — conditions at the PCT junction at 1,830 m can change rapidly.

• Backpack: For a day hike, a 20–28 L pack suits the load. The Hyperlite Mountain Gear Aero 28 is an excellent ultralight DCF option that sheds the volcanic dust endemic to this trail and handles any creek splash. For overnight trips into Mt. Adams Wilderness, the Hyperlite Mountain Gear 2400 Windrider delivers 40 L of waterproof carry at under 600 g. Those packing extra layers, a bear canister, or cold-weather kit will find the Osprey Aether 65 a burly and well-ventilated alternative for multi-day objectives.
• Footwear: Trail runners suit the dusty, well-maintained lower section. Lightweight hiking boots with ankle support are preferable on the rocky upper meadow terrain and for any lingering snowfields in early season. Gaiters are useful in July when the trail surface is soft and silty.
• Layering system: Even in August, the PCT junction at 1,830 m can drop to 5 °C when cloud moves in. Carry a mid-layer fleece or insulated jacket and a waterproof shell at minimum.
• Water: East Fork Adams Creek at approximately 2.5 km is the last reliable source before the PCT; carry a filter or purification tablets. Fill up here and bring 2–3 litres for the upper ascent and the descent.
• Sun protection: UV intensity on open volcanic slopes is high. SPF 50+ sunscreen, a wide-brimmed hat, and UV-blocking sunglasses are essential from the tree line upward.
• Navigation: The upper trail can be difficult to follow on descent in poor visibility. Download an offline map to your phone before departure and carry a compass as backup. See our guide on how many calories you need on a full hiking day to plan your food supply for the sustained effort this trail demands.
• Trekking poles: Recommended for the steep, loose rocky section approaching the PCT junction and for creek crossings in early season when the East Fork runs fast.

Frequently Asked Questions

When is the best time to hike Killen Creek Trail #113?

August is the best single month to hike Killen Creek Trail #113. The trail is typically snow-free to the PCT junction, wildflowers are at peak bloom across the subalpine meadows — lupine, Indian paintbrush, aster — and Mt. Adams views are sharpest in the clear morning air before afternoon clouds build. The accessible season runs from early July to mid-October, though early-season hikers should expect snowfields on the upper trail and high creek crossings through the first half of July.

How difficult is Killen Creek Trail #113?

The trail is rated hard. Over 5 km it gains 701 m of elevation with no flat sections, averaging a 14% gradient throughout. The lower 2 km are straightforward on a well-maintained forest path. The upper section above the sheepherder cabin site becomes rocky and requires route-finding on loose volcanic substrate. Strong fitness and sure-footedness are recommended; no technical climbing or mountaineering skills are needed to reach the PCT junction — that comes only if you attempt the glacier above.

How long does it take to hike Killen Creek Trail #113?

Most hikers complete the 5 km ascent to the PCT junction in 2.5 to 3.5 hours, depending on fitness and how long wildflower stops last. Allow 1.5 to 2.5 hours for the descent, which requires care on the rocky upper section. Budget a full day — roughly 5 to 7 hours total including breaks — to do the trail justice and allow for the optional 1.9 km extension northeast along the PCT to Killen Creek Meadows.
