The trail: This stretch follows the south rim of the Snake River Canyon from the Perrine Bridge toward the east, where a new trail extension offers great views of Pillar Falls. Wide asphalt trail all the way.

Allowed: Pedestrians, bicycles, wheelchairs and leashed dogs. No motorized vehicles other than wheelchairs.

Where to park: You have options here. The three best places to park for easy trail access are the east side of Sportsman’s Warehouse, the west side of Best Buy or the new visitor center just west of the bridge.

At its east end, the trail connects with Pole Line Road in two places, but that portion of Pole Line has no good parking and is decidedly unfriendly to bicycles and pedestrians.

The experience: This popular trail east of the bridge — like its counterpart running west from the bridge — is an easy place to get a quick taste of canyon-rim walking. You’ll see a lot of tourists photographing the canyon and the bridge or watching BASE jumpers.

If you parked at the visitor center, your walk to the east will take you under the guts of the bridge, a massive and exhilarating sweep of metal that’s a Twin Falls icon. Don’t be surprised to see BASE jumpers hop over the rock wall under the bridge; some hike up from a landing zone on the canyon bottom.

In front of Sportsman’s Warehouse and its strip mall fellows, you’ll pass canyon overlooks, benches and a public sculpture dubbed “The Twins” — two female figures with flowing hair and dresses, colored to mimic the landscape of desert rock. (Hint: At the overlook in front of Michaels and Famous Footwear, you’ll get a better perspective for watching parachute action than beside the bridge.)

In the Snake River below, motorboats, kayaks and stand-up paddleboards pass on their trip between Centennial Waterfront Park and Pillar Falls. Above, raptors soar in long, slow circles, riding the currents.

Though metal railings line the overlooks, much of this wide, paved trail is unfenced for unhindered views of the gorge. The rim is just a few feet away, so keep pets and children under control.

As your walk to the east follows the rim, you’ll see the towering rocks of Pillar Falls appear upstream. With good eyesight or a long camera lens, you might spot boaters exploring the rocks at the base of the pillars as the river swirls around them — or someone particularly adventurous at the top of a pillar.

The trail passes several houses before abruptly turning south to bypass an elaborate canyon-rim house. Until last fall, you had two choices: Consider this a dead-end and turn around, or continue south to Pole Line Road, which lacks sidewalks and bicycle lanes here.

Now, a newly paved stretch of trail more than 2,000 feet long rejoins the rim after skirting the house and its gated driveway.

Apparently, a lot of trail users haven’t yet discovered this extension, so you might have it to yourself. The adjacent lots are still an empty, weed-filled expanse, and the trail here is a wonderful place for watching the crowded airspace: the raptors and swirls of songbirds that love the canyon’s edge.

The view of Pillar Falls keeps getting better, and that distant dirt mound on the rim is where daredevil Evel Knievel attempted his canyon jump. When you stop for photos, beware of splinters from the wooden fence that lines this trail segment.

The trail swings south a second time, connecting with Pole Line near Eastland Drive and the Mormon temple. From there, walkers’ feet have created a narrow track toward the neighborhood to the east. But for most trail users, this is the place to turn around and enjoy the shifting canyon perspectives on the way back.

Notes: You’ll find bathrooms and drinking fountains inside the visitor center and the lobby of Sportsman’s Warehouse, both open seven days a week. The visitor center serves free coffee. Best Buy, too, has fountains and bathrooms, but in the back of the store.

East of the commercial area, the canyon-rim trail is unlighted at night. During the day, shade is scarce.

Walking a dog? You’ll encounter a few trailside garbage cans, but bring your own bags for poop scooping; the bag dispensers are chronically empty.
