Sentinel Pass via Larch Valley Trail

Start just beyond Moraine Lake Lodge. The first roughly 2 km climb through forest on switchbacks gains about 300 m and offers few open views. At the fork, take the right branch for Larch Valley; the left goes toward Eiffel Lake, a separate hike. Above the switchbacks, the grade eases and the larches open around Minnestimma Lakes, with the Ten Peaks rising beyond Moraine Lake. Alpine larches are conifers that turn gold before dropping their needles. The color window is brief and shifts from year to year, usually around late September or early October.

At Minnestimma Lakes, the pass hike keeps going. The final roughly 1 km rises about 170 m on steep switchbacks across loose rock and scree. This is the roughest part of the day, so slow down and watch your footing; the lakes are a good turnaround if you would rather skip it. On the approach, look for a small alpine tarn with Mount Fay and glacier views beyond the larches.

Sentinel Pass is a high saddle between the valleys. From the top, look into Paradise Valley and back toward the Ten Peaks. The open view is a good place to stop for lunch before retracing the same trail. For a photo, include some of the rocky trail in the foreground with the larch basin behind it; that gives the wide mountain view a sense of scale. The trail continues toward Paradise Valley, but that is a separate, much longer route with different exit logistics. This row does not include the descent from the pass or a Mount Temple scramble.

Expect sustained climbing, not a stroll to a viewpoint. The forest switchbacks are steady, and the final pitch is steep and rocky. Parks Canada lists this route among its difficult trails and says the alpine approach is exposed to avalanche hazard; travel is not recommended from mid-October to mid-June. Dogs are allowed on trails in summer unless a restriction is posted, and must stay leashed and under control. Moraine Lake Road is closed to personal vehicles year-round, so arrange a Parks Canada shuttle, transit or authorized tour when service is operating.

For the larch forest and lakes without the last climb, take the distinct Larch Valley/Minnestimma Lakes out-and-back and turn around at the lakes. Parks Canada lists that option as 4.5 km each way, about 570 m of gain and 3.5–4 hours round trip. It shares the long forest approach but skips the steep final switchbacks to Sentinel Pass.
