Mt Toll - 9.1 Miles Round-Trip
Mt Toll (12,979') is located 4.55 miles from Mitchell Lake Trailhead in the Brainard Lake Recreation Area. Though no maintained trails reach Mt Toll, well-established cross-country routes lead approximately two miles past Blue Lake (11,355') to the summit.
The routes are not technical when free of snow, but still physically demanding and should only be attempted by experienced hikers. Visitors will enjoy several lakes, abundant flowers and miles of open alpine travel on the hike to Mt Toll:
The trail moves quickly to Mitchell Lake, which occupies a damp flat at the base of Mt Audubon (.85 miles : 10,725'). It crosses Mitchell Lake's inlet (1.1 miles) and steepens into the center of the valley above several outlying lakes. Look for moose in this willow-lined corridor.
The trail undulates through treeline to a wide cascade and crests just above the east shore of Blue Lake (2.55 miles : 11,355').
Blue Lake fills a large rock basin framed by Little Pawnee Peak (south), Mount Toll and Paiute Peak (west) and Mt Audubon (north).
Here the maintained trail ends and you must choose your route to Mt Toll, determined by which shore of Blue Lake you'll climb to reach the upper valley.
Ultimately you'll need to be in the southwest corner of the valley for a non-technical ascent, so the most direct approach is up the south shore. The north shore route is longer but more scenic, highlighted by Upper Blue Lake and long stretches of open snowfields.
The following description scales the north shore of Blue Lake into the upper valley:
Follow the social trail around Blue Lake's north shore to begin the first climb (2.75 miles : 11,379'). Though marked by cairns, thick brush, snow and talus make the exact path difficult to follow.
Keep an intuitive heading into the upper valley, which widens considerably as you progress. The cross-country route levels on a wide, rocky bench about 100 yards from Upper Blue Lake (3.35 miles : 11,901'), which fills a rocky depression between Mt Toll and Paiute Peak.
Here you must begin making your way south across the valley. From Upper Blue Lake, scale the talus slope to the south, which crests over a massive perennial snow bowl.
Drop into the bowl and aim for the southwest corner of the valley. Once across (3.95 miles : 12,090'), you must climb a near-vertical wall to reach the saddle between Little Pawnee Peak and Mt Toll. Improvise your way up, avoiding slick snow and loose rock.
Travel levels on the saddle between Little Pawnee and Toll with your first glimpse over the divide (4.25 miles : 12,540'). Identify a good line up Mt Toll's south side for the .3 mile, 439' push to the summit.
While the terrain is initially clear, talus quickly absorbs any path you take and requires a very careful scramble to the summit. Remain patient and steer clear of drop offs and couloirs.
The Mt Toll summit (4.55 miles : 12,979') is small and pointy with one rock wind shelter. Panoramic views include Little Pawnee Peak (12,466'), Pawnee Peak (12,943'), Shoshoni Peak (12,967'), Apache Peak (13,441') Niwot Ridge, Paiute Peak (13,088'), Mt Audubon (13,223') and peaks from Rocky National Park, the Never Summer Range and Gore Range.

Worth Noting
- The descent off the summit and cross-country travel back to Blue Lake can be equally demanding and time consuming. Plan travel time accordingly.
- Though only .6 miles long, the terrain between Blue Lake and Upper Blue Lake can be difficult to navigate. Steep talus, lingering snow, large boulders, and thick willow patches that hide terrestrial pitfalls may slow travel. In some instances it's quite possible to become 'cliffed out'. Tread carefully on this stretch.
- Most of the trail to Mt Toll runs at or above treeline, and is highly exposed to the elements. Anticipate strong sun, wind, cool temperatures, and rapidly changing weather conditions. Carry versatile layers, sun protection, and ample water. Get a very early start to avoid afternoon thunderstorms. Only fit and experienced hikers should attempt travel beyond Blue Lake to Mt Toll.
