Porcupine Lookout Trail

Overview

This is a remote, high-reward spur off the Waterton Valley corridor that climbs steadily to a historic fire-lookout site with enormous views. From the Waterton Valley junction, it’s about 4.9 miles one way with roughly 2,700 feet of gain via a long series of switchbacks. The grade is surprisingly even—more of a sustained grind than a lung-buster. Expect meaningful solitude and a real backcountry feel.

Access and Route

Most hikers stage from the Kootenai Lakes backcountry camp or approach through the Goat Haunt area, then take the spur from the Waterton Valley Trail. Early on you’ll ford the Waterton River, which can be deceptively deep—even into September—though the current is typically slow. Soon after, you’ll cross Valentine Creek twice in quick succession; keep your water shoes on between those crossings. Once on the mountain’s base, the trail switchbacks through forest before breaking into subalpine terrain.

Scenery and What You’ll See

Views build as the trees thin: up the Valentine Creek drainage at first, then the big stuff from the lookout. You’ll peer straight down at the Kootenai Lakes complex—prime moose habitat—often spotting tiny dark dots leaving wakes in the ponds below. Across the valley, Mount Cleveland dominates the skyline, with the Stoney Indian Peaks nearby. Look north to Waterton Lake, and around to Carter Glaciers, Vulture Peak, Two Ocean Glacier, and the tops of Rainbow and Carter Peaks.

Flora and Wildlife

Lower down, watch for mountain flowers like arnica and thimbleberry in dense forest. Higher up, subalpine fir gives way to beargrass and alpine wildflowers. Wildlife is classic Waterton Valley: moose in and around Kootenai Lakes, plus deer and squirrels.

Difficulty and Trail Character

While the elevation gain is serious, the switchbacks keep the grade friendly. The real crux is water: an unbridged, often-deep Waterton River ford and multiple Valentine Creek crossings. This is a true backcountry objective with very low use.

Best Time to Hike

Aim for late summer into early fall when water levels drop; early season fords can be nearly impassable. You’ll get fine light most of the day thanks to the broad valley views, but late afternoon often brings the most dramatic contrast across the Waterton Valley.

Tips and Tricks

• Plan an overnight itinerary; most people visit from nearby backcountry camps, and an overnight permit is typically part of the equation.
• Bring dedicated water shoes or sandals, trekking poles, and unbuckle your pack for the fords. Expect cold water and possible waist-deep conditions in the river.
• Carry bear spray and know how to use it; this is remote grizzly country with minimal traffic.

Who Will Love It (and Who Won’t)

If you crave solitude, can handle cold-water fords, and want big, classic valley-and-peak views, this lookout punches way above its popularity. If you’re after a simple day hike from a car with no logistics, look elsewhere.
