Summit Lake

Overview

Summit Lake is a small, tranquil alpine lake tucked along the Carthew–Alderson Trail, east of Cameron Lake and near the Continental Divide. Sitting around 2,075 m, it’s the kind of place that feels remote yet rewards the effort with big scenery.

Setting and Views

The lake rests between Mount Carthew and Mount Custer with broad, open terrain around it. From the lakeshore, you get the classic view framing Chapman Peak to the left and Mount Custer to the right—one of the most photographed scenes on the traverse. Expect alpine meadows, subalpine forest, and sections of burned forest and blowdown visible along the approach.

Getting There

You’ll reach Summit Lake via a steady climb on long, comfortable switchbacks from the Cameron Lake trailhead, or encounter it mid-route on the Carthew–Alderson traverse. There’s no road access; it’s strictly a hiking destination. Use the official park map to confirm current routing and any closures or restrictions before you go.

What to Expect

Think serene shoreline breaks, wildflower meadows in season, and expansive ridgeline views just above the lake. Many hikers treat Summit Lake as a scenic rest stop before continuing higher on the traverse. It’s on a marquee route, so don’t expect solitude all day, but the setting still feels wonderfully wild.

Wildlife and Etiquette

This is prime backcountry habitat. Review Parks Canada’s day-hiking guidance and practice Leave No Trace—pack out everything and keep a clean camp for the sake of wildlife and fellow hikers.

Essentials and Amenities

Summit Lake is undeveloped: no toilets, no picnic tables, no campground, no treated water. Bring everything you need and treat any lake water before drinking. Parking and facilities are at the trailheads, not at the lake.

Best time to visit

Plan your visit as part of a Carthew–Alderson day when the route is open per Parks Canada advisories. Use the park’s official map and current notices to time your hike and avoid any area restrictions.
