About Old Pipeline Bed Trailhead
Old Pipeline Bed Trailhead is a short, easy riverside trail in Tumwater Canyon on the Wenatchee River, about 2 miles west of Leavenworth, Washington on US Highway 2, within the Okanogan-Wenatchee National Forest. The trail follows the bed of a historic early-1900s wooden penstock (water pipeline) that once powered a plant used to electrify trains through the Cascade Tunnel, and it passes several sandy river beaches that serve as swimming hole access points for wading, sunbathing, and cooling off.
The trail runs along the Wenatchee River through Tumwater Canyon, a dramatic stretch lined with cottonwoods and pines beneath tall cliff faces, including the climber-popular Castle Rock across the water. The route follows the historic penstock grade, an old wooden pipeline bed listed on the National Historic Register, and continues upriver to a cliff face where the maintained path ends.
Swimming at Old Pipeline Bed Trailhead
Visitors describe clear, turquoise river water and sandy beach pull-outs along the trail suited to wading, relaxing, and swimming in calmer eddies, but the Wenatchee River's main current in this canyon is powerful (the Chinook-derived name 'Tumwater' means roughly 'strong/rough water'), and the Washington Trails Association explicitly warns against swimming in the main channel because it can sweep even strong swimmers downstream; a seasonal side creek about half a mile in is described as a safer spot to cool off. This spot suits casual waders, families, and sunbathers more than swimmers looking to swim across or against the current.
How to get to this swimming hole
From the gas station at the junction of Icicle Road and US Highway 2 in Leavenworth, drive about 1.7 to 2 miles west on Highway 2 (near mileposts 97-98) and turn into the small parking pull-off on the left next to the river.
Parking: Small, non-descript pull-off parking area next to the highway/river holding roughly a dozen vehicles; a day-use fee (reported around $5, payable via a recreation app/self-service) or a Northwest Forest Pass / America the Beautiful Pass is required.
The hike in
Penstock Trail / Tumwater Pipeline Trail (also called Old Pipeline Trail), following the historic pipeline/penstock grade
- To the water
- Not precisely documented in mileage, but sandy river beaches/wading pull-outs are described as starting close to the parking area along the first stretch of trail; a separate seasonal side creek, described by WTA as a safer place to cool off than the main river, is about 0.5 mi in.
- Time on foot
- Roughly 1 hour for the full 2-2.4 mi round trip; the closest river beaches are only a few minutes' walk from the parking pull-off.
Difficulty: Easy - flat riverside walking, about 100 ft of total elevation gain.
Trailhead: Small paved pull-off on US Highway 2 near milepost 97-98 in Tumwater Canyon, about 1.7-2 miles west of the Icicle Road/Highway 2 junction (gas station) in Leavenworth, WA.
The maintained trail runs about 2 to 2.4 miles round trip total (WTA measures 2.4 mi RT with ~100 ft gain) along the old penstock bed to a cliff face where it dead-ends; river-access beaches are concentrated along the first portion of that distance, nearest the trailhead.
Many visitors likely just walk a short distance to the nearest beach rather than doing the full out-and-back to the cliff face at the end.
Plan your visit
Bringing kids
OK with supervision
The trail itself is flat and short, and one visitor called it 'great for people of all ages,' but trail reports explicitly warn the Wenatchee River's main current here is powerful enough to sweep even strong swimmers downstream (the name Tumwater derives from a Chinook word for 'strong/rough water'). Visitors also flag exposed metal pipeline debris and uneven rocky terrain along the path. Best suited to wading and playing in calm beach margins and eddies under close supervision, not letting kids swim in the main channel.
Parking
Paid, ~$5 day-use fee (payable via a recreation/self-pay app per reviewers) or a valid Northwest Forest Pass / America the Beautiful Pass
Small, non-descript paved pull-off directly on US Highway 2 next to the river, holding roughly a dozen vehicles; not obviously visible from the road until you're on top of it. Visitors note it is not wheelchair accessible.
Restrooms
Yes
Two non-flushing outhouse-style vault toilets near the trailhead/parking area (no running water), per visitor reports.
Water clarity
Clear
Multiple visitors describe 'clear turquoise river water,' with one calling the fall colors combined with the water 'breath-taking.' This is consistent with a Cascades snowmelt-fed river in a rocky canyon. Clarity likely drops during spring runoff, when trail reports note the trail can flood and the river runs high and dangerous.
On the water
Restrictions: WTA explicitly warns that the main river current in this Tumwater Canyon reach is powerful ('strong water') and unsafe for swimming/casual paddling; no evidence was found of casual kayak, canoe, paddleboard, or tubing use at this specific pull-off.
The Wenatchee River is used for whitewater rafting and kayaking on other reaches (e.g., between Leavenworth and Cashmere/Monitor, downstream of this canyon), but no source found ties any commercial rafting or paddling trips specifically to this Tumwater Canyon trailhead.
What regulars say
Visitors describe clear, turquoise-colored river water and sandy beach pull-outs suited to wading and relaxing, and call the trail easy and good for all ages, but they also flag hazards: exposed metal pipeline debris along the path, rocky and uneven terrain, limited and paid parking, and no wheelchair access. The strongest caution comes from published trail reports, which explicitly warn hikers against swimming in the main river current and point to a smaller side creek about half a mile in as a safer alternative.
Backstory
The trail follows the bed of a historic wooden penstock (water pipeline) built in the early 1900s that carried water to power a plant used to electrify trains through the nearby Cascade Tunnel; remnants of the pipeline structure are listed on the National Historic Register.
