Redrock Lake

Overview

Redrock Lake is the calm, scenic middle act on the Swiftcurrent Pass Trail—framed by big Many Glacier peaks and fed by the wide, stair‑stepped cascades of Redrock Falls. It’s an easy win: mostly flat walking, lots of shade, and a high chance of wildlife along the way.

Getting There & The Walk

Start from the Swiftcurrent Pass Trail just past Swiftcurrent Motor Inn in the Many Glacier area. The out‑and‑back to the falls (with the lake en route) is roughly 3.6–4 miles round trip with minimal elevation, and the path is well‑traveled and forgiving. You’ll pass a short spur to Fishercap Lake, then reach Redrock Lake where the falls appear across the water; continue around the lake to get closer.

What You’ll See

Expect classic Many Glacier views, with Mount Grinnell and nearby summits rising above the valley. Redrock Falls pours into the lake in wide tiers, adding sound and movement to the shoreline. Shore access is somewhat limited—one of the best touch‑the‑water spots is right where the trail first hits the lake.

Wildlife

This corridor is known for moose (especially at Fishercap Lake at dawn/dusk) and has regular bear activity in brushy stretches. Give all wildlife space, carry bear spray, hike in a group when you can, and make noise in dense vegetation. Bug pressure can spike in summer, so bring repellent.

Geology: Why the Rocks Are Red

Those striking red slabs are ancient Belt Supergroup rocks. Iron within the sediments oxidized over geologic time, giving the argillite its rusty hues, while green layers formed in lower‑oxygen conditions. It’s Glacier’s deep time on full display.

Fishing & Play

Anglers find brook trout here, commonly in the 10–12 inch range, with both spin and fly methods working. For more solitude (and less skittish fish), some anglers venture to the quieter southern shoreline. Casual swimmers sometimes take a dip—pack a towel and keep it low‑impact.

Practicalities

• Parking: Use the large lot by Swiftcurrent Motor Inn; it serves multiple popular trails and can fill early.
• Facilities: No restrooms at the lake or along the trail—use facilities at the motor inn area before you start.
• Connectivity & pets: Expect little to no cell service. No pets on park trails.
• Extensions: Feeling good? Continue past the falls toward Bullhead Lake for bigger scenery without much extra effort.

Best Time to Visit

Late June through September typically offers the best trail conditions. Go early morning or late afternoon for easier parking, softer light on the water, and better moose odds. Weekdays are quieter than weekends. In peak season, access to Many Glacier may require a vehicle reservation—check current NPS guidance before you go.
