Mount LeConte via Trillium Gap Professional Review and Guide
"For a trip to Mount LeConte, this route features wildflowers, a scenic waterfall, and views. You can’t go wrong with either hike. A feature of this hike is that it is wetter for much of the route, crossing numerous stream branches, and it is rife with verdancy.
Another feature of Trillium Gap Trail is that it is the route used by the llama train to supply LeConte Lodge. The access road (Roaring Fork Motor Nature Trail) is closed Dec 1–Mar 31. An alternate winter access route is to hike Trillium Gap Trail from the Rainbow Falls parking lot, but that access makes the hike 2.3 miles farther one-way, or 4.6 miles round-trip. If you wish to spend the night at LeConte Lodge on Mount LeConte’s summit, you’ll need to make reservations well ahead of time. The backcountry shelter on Mount LeConte also requires reservations, as do all other shelters in the park."
