Burroughs Mountain Trail

Overview

If you want the in-your-face Mount Rainier experience, this is it. Starting from the Sunrise area, the Burroughs Mountain Trail climbs above treeline to a stark alpine plateau with some of the park’s closest views of the Emmons and Winthrop Glaciers. Expect a mostly exposed, rocky path, big scenery, and options to tailor your day. The classic full loop is about 9.5 miles total; shorter out-and-back variants reach the 1st or 2nd Burroughs if you’re not up for the whole thing.

Route options and mileage

From Sunrise Visitor Center, most hikers head over Sourdough Ridge toward the Frozen Lake junction and then up to the Burroughs. Turn around at whichever summit you choose—or make a loop by returning via Sunrise Rim back to the Sunrise parking lot. Typical totals: about 4.7–5 miles round trip with ~900–1,000 feet of gain to First Burroughs; roughly 7 miles round trip and ~1,350–1,400 feet of gain to Second Burroughs; and about 9–10 miles with ~2,500 feet of gain to Third Burroughs. The mountain rises to over 7,800 feet, so you’re truly in high country.

What you’ll see

This ridge-of-three “Burroughs” serves nonstop, front-row glacier views and a dramatic “mountain against a mountain” feel as the route hugs the Winthrop side of Rainier. You’ll traverse fragile alpine tundra—rare and easily damaged—interspersed with rocky benches, moraines, and glacially carved terrain. In mid-to-late summer, wildflowers brighten meadows along the Sunrise Rim. Common wildlife sightings include marmots sunning on rocks, mountain goats roaming the slopes, and occasional elk.

Trail feel and difficulty

The tread is natural and often rocky, with notable steeps between Frozen Lake and First Burroughs and again on the push toward Third. There are narrow sections with drop-offs and zero shade once you’re on the ridge. It’s a moderate outing to the First/Second Burroughs and a legitimately strenuous day if you commit to the Third or the full loop.

Best time to hike

Late July through September offers the most reliable snow-free travel, peak wildflowers, and clear vistas. Early season (June into early July) can leave steep slopes snow-covered and hazardous—check conditions before you go. Start early to beat the Sunrise parking crunch and to enjoy softer light on Rainier’s glaciers.

Tips

• Do the loop if you can: up Sourdough Ridge, back via Sunrise Rim for varied views and fewer retraced steps.
• Bring sun and wind protection—this is exposed alpine terrain and weather shifts fast.
• Carry all the water you need; there’s no potable water on the route. Restrooms are at Sunrise only.
• Stay on constructed trails to protect the delicate tundra; it recovers slowly in this harsh environment.
• Choose your turnaround point realistically. The trail is forgiving that way—1st, 2nd, or 3rd Burroughs all deliver.
