Eiffel Peak Trail

Why hike it

Eiffel Peak is a bona fide alpine scramble rising above Moraine Lake with knockout views over the Valley of the Ten Peaks, Larch Valley, hanging glaciers, and scree-choked basins. It’s far tougher than the neighboring Eiffel Lake/Larch Valley hikes, but the summit panorama makes the effort worth it for experienced hikers.

The route in a nutshell

Start on the popular Moraine Lake path used for Larch Valley and Eiffel Lake. After the switchbacks, go right toward Larch Valley (left goes to Eiffel Lake). Shortly into Larch Valley, leave the maintained trail, cross a small creek, and follow cairns toward Eiffel Peak’s east/southeast ridge. The ridge is mostly hiking (class 1–2) with increasingly loose rock and hands-on moves near the top (class 2+). You’ll pass two distinct towers (one light grey, one dark grey) before the summit. Do not try to ascend from Eiffel Lake—there’s no viable route up from the lake.

Stats and effort

Plan on 7.5–8.0 miles total (out-and-back, including the Larch Valley approach), around 3,900–4,000 feet/1,200 m of gain, and 6–8 hours for most parties. Expect route finding, a creek crossing, and steep scree. Even in summer, snow can linger high up, and early-season or autumn snow can raise the technical feel.

Scenery and seasonality

This is classic Rockies geology on display: moraines, talus, and hanging glaciers, with the Ten Peaks ringing the basin. In late September to early October, larch trees in Larch Valley flare golden—arguably the most photogenic time to go. Summer brings longer days and generally easier travel, but shade is limited and upper snow patches may persist. Clear fall days are prime; early storms are common, so bring layers.

Logistics and warnings

The trailhead at Moraine Lake is shuttle-only—private vehicles aren’t permitted. Reserve shuttle spots early. Carry bear spray and watch current advisories; group-of-four access can be required in this area at times. This is an unmarked, cairned scramble above the maintained trail. Missing the turnoff leads to wasted effort or hazardous terrain. Helmets aren’t a bad idea for the loose rock. Dogs on-leash are allowed on the lower trails, but the upper scramble is not dog-friendly, and getting pets on shuttles can be tricky.

Who will love it (and who won’t)

If you want a hands-on summit objective that’s less technical than Mount Temple but with big-mountain payoffs, Eiffel Peak delivers. If you prefer staying on signed, maintained paths, choose Larch Valley or Eiffel Lake instead—you’ll still get world-class scenery without the scramble.
