Floe Lake

Overview

Floe Lake is the showpiece of Kootenay’s Rockwall country: pure blue water tucked beneath towering limestone and glacial cliffs. This is a demanding out-and-back with real payoff. It’s 13.0 miles total (21 km), roughly 6.5 miles (10.5 km) each way, rated hard with about 800 m of elevation gain. Expect narrow, sometimes overgrown singletrack, sun exposure through old burn, and a final grind of switchbacks before the lakeshore reward.

Route Experience

From the trailhead on Highway 93S, a sturdy bridge crosses the Kootenay River almost immediately, followed by a second bridge about 1.8 km in. The trail then traverses the southern face of Numa Mountain through meadows and burnt timber—good views, little shade. Water is limited for a long stretch; a creek around 6.5 km is a classic rest and refill spot. The last 2 km climb steady dirt switchbacks that pack in roughly half the total elevation gain. Plan about 4 hours to reach the lake; the return is often a touch quicker. Photographers: morning light usually treats Floe Lake best, while the basin falls into shadow early.

Camping at the Lake

If you can snag a spot, overnighting elevates the whole experience. Floe Lake Campground has 18 designated sites and requires a backcountry reservation and permit. Fees apply per person per night, plus a reservation fee. Facilities include pit toilets, bear-proof storage lockers, and two scenic dining areas with picnic tables; fires are not allowed, so bring a stove. Sites are first-come on arrival (by permit), one tent per site, up to five people, with a maximum stay of three nights. Store all food in lockers and keep a clean camp—staff patrol and violations can void permits.

Best Time to Hike

The reliable season runs roughly from July 10 to early October, when higher sections are typically free of lingering snow and the campground is bookable. Summer brings wildflowers and long daylight; late September often delivers golden larches above the lake. Outside this window, expect snowbound travel and cold conditions. Weekdays and early starts help with parking and trail traffic.

Add-On: Numa Pass

If you’re camping, tack on the 5 km round-trip to Numa Pass from the lake (about 350 m extra gain). It’s a fast favorite for huge views over Floe Peak and a valley peppered with larches—especially striking in early fall. Strong day hikers can add it, but that pushes total stats well past a casual day.

Practical Tips and Safety

There’s no cell service on the trail or along Highway 93S—carry offline maps and consider a satellite communicator. Travel in bear country: carry bear spray, make noise, and use the provided lockers. Long pants help in brushy sections; sun protection matters in the burn. Nights at the lake can be cold even in mid-summer. Always check current trail conditions and closures before you go, and remember a valid park pass must be displayed at the trailhead.
