Phelps Lake

Overview

A classic Teton glacial lake (about 750 acres) tucked beneath Death Canyon, Phelps Lake blends easy-to-love shoreline rambling with big mountain views. It’s popular for good reason: clear water, a mellow loop, and that crowd-pleasing Jumping Rock on the east side.

Getting There

You’ve got two main gateways:

• Laurance S. Rockefeller Preserve (LSRP): The gentler approach with a more contemplative vibe. Parking is limited to about 50 spots and often full by mid‑morning in summer.
• Death Canyon Trailhead: Reached via a short, rutted dirt road. The approach drops steeply toward the lake (about 600 ft over 0.8 mi), which you’ll climb back on the return.

Moose‑Wilson Road leads to LSRP, has no RV or trailer access, and can see periodic closures. Check status before you go.

Trails and What You’ll See

The Phelps Lake Loop runs roughly 6.4–7.2 miles with around 1,060 ft of gain depending on your start. Expect forested stretches, aspen and pine, wildflowers in season, and frequent windows to the water and surrounding peaks. The east side and LSRP approach are busiest; swing to the west side if you want more breathing room and better odds of wildlife.

Swimming and the Jumping Rock

On warm days, the east‑side Jumping Rock draws a crowd. Bring a towel and be honest about your comfort with cold mountain water and cliff jumping. There’s also a sandy pocket known as Phelps Beach that’s great for picnicking and dipping your feet—just don’t expect built amenities.

Wildlife

Black bears are regularly reported around the lake (and grizzlies are possible). The quieter west side sees more wildlife activity. Moose, deer, marmots, and a variety of birds round out the usual suspects. Carry bear spray and know how to use it.

What to Know

• No services: No food, water fill, or store at the trailheads or lake. Pack everything you need and pack it out.
• Backcountry overnights: A few designated sites exist by permit only.
• Pets aren’t allowed on the trails to or around the lake.
• Bugs can bite in early summer—bring repellent.

Best Time to Visit

• Time of day: Arrive early (before 9 am) to snag LSRP parking and enjoy calm light on the water. Late afternoon brings softer photography light but busier trails and scarce parking.
• Season: Summer is prime for swimming and wildflowers; expect crowds. Shoulder seasons offer quieter loops but colder water and variable weather.
• If you want fewer people: Start from Death Canyon or aim for weekdays and the west shore.

Effort and Safety

From Death Canyon, the return from the Phelps Lake Overlook is a stout uphill—pace yourself and bring plenty of water. Weather changes fast; carry layers. On all routes, stay bear‑aware and hike in groups when possible.
