The trail: From Twin Falls’ Federation Point, east along the Snake River Canyon rim and south along Perrine Coulee.
Allowed: Pedestrians, bicycles, wheelchairs. No motorized vehicles other than wheelchairs.
Where to park: There are two official access points for this prime stretch of trail — a small parking lot at Federation Point, which is at Washington Street’s north end, and parking spaces behind Les Schwab Tire on Pole Line Road. Also, three restaurants that line the trail — Elevation 486, Canyon Crest and Montana Steak House — are informal entry points; the first two have wheelchair-accessible ramps.
The experience: The Federation Point trailhead, a pretty spot beside an enormous power transmission tower, overlooks a stretch of the Snake River, a golf course, dramatic canyon walls and the distant Perrine Bridge. Near the trailhead, a fence-mounted box dispenses dog-poop cleanup bags; you’ll find several trash cans along the trail.
Walking east along the Snake River Canyon rim, you’ll pass more canyon overlooks, trailside benches and tailored business landscapes that alternate with empty dirt lots. Though I’ve sometimes caught whiffs of the sewage treatment plant in the canyon, that smell was absent in early November.
One overlook provides a superb view of Perrine Coulee spilling into the Snake River Canyon, with the bridge and a wide expanse of the gorge in sight, as well. The canyon views from the trail are, arguably, better than those from the famous bridge.
Much of the trail is edged — on the rim side — by decorative iron railings or picturesque log-rail fences. But in other sections the ragged, rocky rim is unguarded, so keep children and dogs away from it.
Behind the Canyon Crest event center, you’ll encounter a closed section of trail, washed out by August’s dramatic flooding. Behind a barrier of orange netting, broken railing dangles over the canyon rim. Bypass that section with a short detour on Canyon Crest’s sidewalks and through its gravel parking lot. The detour includes a short ramp of loose dirt.
Back on the paved trail, the sound of tumbling water signals your approach to the Perrine Coulee’s dramatic fall into the canyon. After a tree-shaded footbridge across the coulee, the trail continues east briefly before dead-ending. Even at the east end, walkers can still hear pops from the gun club near Federation Point.
At the coulee footbridge, walkers and cyclists also can opt to turn south and follow the paved trail to Pole Line Road, where a pedestrian underpass delivers them to the sidewalks on Pole Line’s south side.
Notes: Many stretches of this trail have no lighting at night. Keep pets on leashes. The only restrooms or drinking fountains you’ll find are inside business lobbies.
