Ridge Lakes

Overview

Ridge Lakes rewards a short but punchy climb with two small, turquoise alpine lakes tucked between Brokeoff Mountain and Mount Diller. It’s a fast way to escape into high-country scenery from the south entrance—expect effort, then quiet water, big sky, and a sense of being well above the road.

What You’ll See

As you ascend, the views open to the Sulphur Works hydrothermal area and surrounding peaks, with bursts of seasonal wildflowers like mule’s ears, paintbrush, and lupine near the lower slopes. At the top, the twin lakes sit in a rocky basin—peaceful and photogenic, a prime spot to linger for a snack. In late summer, the lakes separate more distinctly; earlier in the season they can appear joined. Ambitious hikers can push another ~0.3 miles cross-country above the basin to a ridge for sweeping panoramas.

Trail Basics

• Distance: roughly 2.0–2.2 miles round trip
• Elevation gain: about 987–1,045 feet
• Grade: sustained and steep from the start
• Trailhead: Sulphur Works parking area; the path begins near the restrooms on the north side of the lot

Season and Conditions

This route typically comes into shape from July to early October, but snow can linger longer than you’d expect. Early season travel may involve patches of snow, slick footing, and occasional route-finding challenges—an offline map helps. Afternoon thunderstorms (and even brief hail) can pop up; start early and keep an eye on the sky.

Practicalities

There are restrooms at the Sulphur Works trailhead. Food and water are available at the Kohm Yah-mah-nee Visitor Center about a mile south. Dogs are not permitted on the trail. Backpackers need a permit if you plan to stay overnight—there are some sheltered tent spots near the lakes. Hardy swimmers sometimes brave the deeper section of the southern lake in late summer; expect very cold water.

Wildlife

This is black bear and mule deer country. Dawn and dusk are most active times; give wildlife space and store food securely. You’ll also hear plenty of birds in the subalpine scrub around the basin.

Is It Worth It?

If you like maximum payoff for a short effort—and don’t mind huffing up a steep mile—Ridge Lakes is a gem and often quieter than the park’s headline hikes. If steep climbs or lingering snow aren’t your thing, save it for midsummer conditions.

Best Time to Visit

• Time of day: Early morning for cooler temps, easier parking at Sulphur Works, and calmer water for reflections.
• Day of week: Weekdays are quieter.
• Photography: Morning side light and late-day golden hour both work; midday sun shows off the lakes’ clarity but can be harsh.
• Season: July–September for dry trail and wildflowers; expect snow navigation earlier.
