Phelps Lake Trail - 3.7mi Moderate Hike

Q: How hard is the elevation gain?

1,080 feet over 3.7 miles sounds moderate, but you gain most of it on the return hike when you're tired. The descent is easier, but the ascent tests your fitness. Trekking poles are not optional—bring them.

Q: Is the trail closed in winter?

Typically, yes. The steep switchbacks with snow and ice are dangerous. Check the NPS website for current conditions before November.

Q: How much water should I bring?

Minimum 2 liters. 3 liters is better. The canyon is exposed and dry. You can filter at the lake, but carry enough to reach it.

Overview

About This Trail

The Phelps Lake Trail is a 3.7-mile moderate out-and-back hike with 1,080 feet of elevation gain, featuring a series of switchbacks down to an alpine lake and an exposed overlook. The first half descends via a well-defined trail to the lakeshore; the return climb is strenuous uphill and demands real fitness and hydration. Expect rooty, rocky terrain with multiple elevation swings. The payoff: a mountain lake framed by the Teton range, accessible as a day hike but only if you respect the altitude and prepare for a tough ascent home.

Trail Highlights

Phelps Lake sits in a high alpine basin with views of the Teton range. The descent via switchbacks leads to the lakeshore, where the Phelps Lake Loop Trail offers further exploration. From the overlook, the panorama is the reward for the work.

Insider Tips

• The overlook view is good, but don't stop there. Drop to the lakeshore for the real payoff. • The false flat near the lake can trick you into thinking you're done. You still have the 1,080 ft climb back. • Most hikers turn around at the lakeshore, so the loop trail extension has fewer crowds. • Start by 6 AM in peak season to avoid the conga line and afternoon heat.

Best Season to Hike

Summer and Fall

Hiking Tips

Carry 2-3 liters of water minimum—canyon sun is relentless on the return.
Wear trekking poles. The descent is easier with them; the ascent is torture without them.
Start early. The hike back is all uphill and slower than the descent.
Bring a sun hat and sunscreen. Shade is sparse.
The trail has rooty obstacles and exposed rocks—watch your foot placement.

Family Info

The strenuous return climb makes this best for kids 10+. Very young children may struggle with the ascent and exposure. Hold hands on steeper sections; the trail has drop-offs. Altitude can surprise lowland families—go slow and bring extra water.

What Hikers Say

Hikers report the descent is fast and the views are rewarding, but the return climb separates the fit from the unprepared. Most say the lake is worth the effort if you bring trekking poles, plenty of water, and start early. The trail is well-maintained and straightforward to follow.
