Overview
A low-traffic valley ramble with outsized views, the Simpson River Trail threads through open meadows and a broad burn scar from 2001, trading shade for constant scenery. Expect a mostly gentle grade, big sky, and a good dose of fire-ecology learning via interpretive signs in the first 1.5 km. This guide assumes the classic out-and-back to the Mount Assiniboine Provincial Park boundary: 17.6 km/10.9 miles total (out-and-back). Dogs are allowed on leash.
Route Options and Distances
You can make this as short or as long as you like. The interpretive segment (about 1.6 km/1 mile one way) is an easy, family-friendly sampler with early views. The main day-hike continues up-valley to the Assiniboine Provincial Park boundary (8.8 km/5.5 miles one way), typically taking about 5.5 hours return for most hikers. Very fit parties sometimes extend farther toward Surprise Creek Campground for a bigger day (roughly 22–23 km return), but that’s a push and best left for long summer days.
Trail Experience
From the trailhead the path first tracks the Kootenay River before turning east to parallel the Simpson River, getting closest in the final stretch. Terrain is mostly mellow, though erosion has created a few short steeper bits. Expect soggy patches bridged by simple boardwalks made from felled logs, and one small brook crossed via a tree bridge (often bypassable at low flow). Past the first 1.5 km, sections can feel brushy and wet. Views stay wide thanks to the burn, with meadows and regrowth framing surrounding peaks. Don’t count on shade.
Hazards and How to Hike It Smart
This corridor still holds many standing burned trees. Give them respect: avoid windy days, move efficiently through snag zones, and take breaks well away from dead timber. Bears frequent the valley and can trigger closures—carry spray, hike in a group, and check same-day notices. In cold months, shaded slopes and the ridge viewpoints ice up; traction (microspikes) and poles make life easier. There’s no cell service—download maps and leave a trip plan.
Seasonal Notes and Best Times
Late June through September brings the most reliable footing and wildflowers. Shoulder seasons can be muddy or icy. As of mid-November 2025, nearby difficult trails in the park are seeing snow/ice, slippery sections, some unmaintained conditions, and avalanche hazard at higher elevations—plan for winter travel, short daylight, and frozen ground. If roads are plowed and you just want a quick outing, the interpretive section makes a satisfying there-and-back without committing to the full valley.
Getting There
Park at the signed Simpson River parking lot on Highway 93 (Banff–Windermere), on the east side of the highway—about 57 km northeast of Radium Hot Springs and roughly 46 km south of the Trans‑Canada junction. A large gravel pullout and a bridge mark the start. The trail officially ends at the Assiniboine Provincial Park boundary; backpackers can continue beyond with proper permits.
Pros
- Fire-ecology interpretive signs make the first 1.5 km engaging and educational
- Choose-your-length day with gentle grades and constant open views
Cons
- Standing burned trees present real hazard—avoid windy weather and keep moving through snag zones
- Soggy, eroded stretches with log boardwalks and a simple tree-bridge crossing
Parking
Signed Simpson River parking lot on BC-93 (Banff–Windermere Hwy), about 57 km NE of Radium Hot Springs; gravel lot on the east side of the highway at the trailhead.
Caution
Expect wet and brushy sections, simple log boardwalks, and a small tree-bridge crossing; standing burned trees can fall—avoid windy days and don’t linger under snags. Bears are common and may prompt closures; carry spray and check day-of notices. In late fall/winter, anticipate snow/ice, slippery travel, unmaintained sections, and short daylight—bring traction and poles.
