Valley Trail Phelps Lake - 13.2mi Strenuous Hike

A lake surrounded by trees as viewed from above.

The Valley Trail from Teton Village to Phelps Lake Overlook is a lung-busting 13.2-mile out-and-back climb with 2,360 feet of elevation gain through alpine forests. The 17% average slope with exposed roots and rocks demands constant attention to footwork and serious fitness. The payoff is a high-altitude vantage over the park's valley lakes. Be honest: this is a beast of a day hike for experienced hikers only.

Facilities & rules

Restrooms At Trailhead: 0
Water Sources: No water sources on trail. Carry all water needed (minimum 3 liters recommended for this distance and elevation).

Safety & strategy

Hazards: Steep elevation gain
Exposed roots and rocks
High altitude exposure
Weather exposure at elevation
Endurance challenge
Lightning risk
Hazard Details: The 17% average slope with 2,360 ft elevation gain creates sustained steep climbing that tests endurance. Exposed roots and rocks throughout demand careful footwork and proper boots. Above 8,000 feet, weather can deteriorate rapidly—afternoon thunderstorms are common in summer. Altitude thins oxygen; most hikers feel it by mile 8.
Best Season: Late spring through fall (June–September); snow blocks higher elevations before June
Best Time To Visit: Start by 6 AM to beat afternoon weather changes at elevation. Late spring through fall (June–September) offers stable conditions; snow blocks higher sections before June. Afternoon thunderstorms are common above 8,000 feet—plan to exit high terrain by 2 PM.
Tips Advice: Carry 3+ liters of water; altitude and distance dehydrate fast
Wear proper hiking boots with ankle support for exposed roots and loose rocks
Trekking poles reduce knee strain on the brutal descent
Bring a map; cell service is unreliable at elevation
Layer up—weather at the overlook is 15-20°F colder than the trailhead
Start pre-dawn if possible; don't underestimate the 13.2 miles

More details

Park Area: Southern Grand Teton / Teton Village area
Trail Markers: Trail is well-established but markers are sparse at higher elevations. A map is strongly recommended.
Dogs Allowed: No—park regulations prohibit dogs on all hiking trails
Biking Allowed: No—hiking only
Shade Level: Partial shade in alpine forests below 8,000 feet; increasing exposure at higher elevations. No protection from afternoon sun or weather at the overlook.
Map Recommended: 1
Snow Dates: Snow typically blocks sections above 8,000 feet from October–May. Verify seasonal conditions with the NPS before your trip.
Mud Season: Early summer (June–early July) may have muddy sections as snow melts. Late spring and early summer are wetter seasons overall.
Bug Season: Mosquito season peaks July–August, especially in shaded forest sections. Bring insect repellent.
Insider Tips: The first 2–3 miles via Jackson Hole Mountain Resort trails are easier than the Valley Trail proper; don't let that fool you—the real grind starts at the official Valley Trail junction
The overlook itself is modest; the reward is the vantage over the lakes below, not a grand vista
The descent is often harder on quads than the ascent; save energy and go slow on the way down
Afternoon weather above 8,000 feet deteriorates fast; be off high terrain by 2 PM
Family Friendly Notes: Not recommended for most families with young children. The distance (13+ miles), sustained elevation gain, and trail hazards (roots, rocks, exposure) require experienced hikers and strong fitness. Older children (12+) with serious hiking experience may manage with close supervision and frequent breaks.
Review Summary: This is a serious alpine day hike that separates committed hikers from tourists. The elevation gain is relentless, and the last 2 miles punish quads, but the overlook vantage justifies the effort. Most experienced hikers rate it brutal but worth it; beginners should skip it entirely.

Frequently asked questions

Can I do this trail with no hiking experience?

No. This is strictly for experienced hikers. The combination of distance (13.2 mi), elevation (2,360 ft), trail obstacles, and altitude will break beginners. Honest answer: don't start your hiking career here.

Is this safe to hike alone?

Yes, with caveats. Cell service is unreliable; if you fall, rescue may be slow. Hike with a partner if possible, carry a map, tell someone your plan, and start early enough to exit by daylight.

Do I need special gear or equipment?

Yes: proper hiking boots (not trail runners), trekking poles to reduce knee strain, a map (cell service unreliable), 3+ liters of water, and a rain jacket. Altitude can sneak up; bring layers.

What if I'm fit but haven't done serious elevation gain?

Elevation is a different beast than flat distance. 2,360 feet over 6.6 miles is a grind. Many fit runners bonk on this trail. Start conservatively, take breaks, and don't let ego override your body's signals.

Can I turn back at any point?

Yes. The trail is out-and-back, so you can bail at any milestone and return the same way. Better to turn back tired than summit fatigued and risk a dangerous descent.

What time of year is safest?

Late June through September is the safe window. Snow blocks sections before June; winter storms and cold are serious hazards. Summer brings thunderstorms; hike early and be off high terrain by 2 PM.
