Amphitheater Lake Trail

Overview

If you want a classic Teton grinder with huge alpine payoff, this is it. Starting from Lupine Meadows, the trail climbs relentlessly to Surprise Lake and then Amphitheater Lake in a glacial cirque below Disappointment Peak. It’s a stout out-and-back of about 9.9 miles total with roughly 3,000 feet of gain, topping out near 9,700 feet at the upper lake. Expect a well-built path, tons of switchbacks, and scenery that gets better with every turn.

What you’ll see

The first miles wind through mixed forest and along a stream before the grade tightens and the switchbacks begin. Openings in the trees deliver big looks across the valley to Bradley and Taggart Lakes. Higher up, the terrain turns rocky and subalpine. You’ll hit Surprise Lake first, then a short push lands you at Amphitheater Lake, tucked in a dramatic, bowl-shaped cirque of granite and talus. Wildlife sightings are common—think marmots and pikas in the rocks, mule deer in the trees, and occasional bigger critters. Around the lakes, mosquitoes can be feisty in mid-summer.

Trail experience

It’s sustained, steep, and simple to follow. The path is well signed and maintained, but the grade rarely lets up. Crowds ebb and flow, yet it’s typically less chaotic than the neighboring Delta Lake route despite sharing the trailhead. Water is scarce after the early footbridge; reliable refills are at the lakes only, and you’ll need to treat anything you drink.

Best times to hike

Aim for late June through September, after the snow has mostly cleared and before fall storms take over. Early and late season can hold lingering snowfields—traction and snow sense help. Summer afternoons commonly bring thunderstorms; start early to tag the lakes and be headed down before weather builds. Buggiest conditions tend to hit mid-summer around the lakes.

Tips

• Start early for parking, cooler temps, and to dodge afternoon storms.
• Bring layers—weather changes fast at high elevation.
• Trekking poles help on the long climb and descent.
• Carry bear spray and know how to use it.
• No dogs are allowed. Day hikes don’t need a permit; a permit is required for the limited backcountry sites near Surprise Lake.
• Confident hikers can explore faint paths beyond Amphitheater Lake toward Disappointment Peak for loftier views.
