Mount Lady Washington - 11.8 Miles Round-Trip

Mount Lady Washington (13,281') is located next to Longs Peak (14,259'), and is one of three peaks that form the Chasm Lake cirque (Mt Meeker, Longs Peak and MLW). No trail leads to the summit, however it’s a relatively short, moderate excursion off the Longs Peak Trail to the top.

The route shares the first 3.25 miles with Chasm Lake to the East Longs Peak Trail, which makes a counter-clockwise arc around the base of Mount Lady Washington to Granite Pass and the Boulderfield. You’ll leave the main trail just before reaching the Boulderfield for a .45 mile, 700’ scramble to the summit:

The trail climbs steadily from Longs Peak Ranger Station past connections for Estes Cone  (.5 miles) and Goblins Forest backcountry campsite (1.1 miles : 10,127’).

Alpine Brook, largely concealed by timber, is the only notable feature until crossing the top of a long cascade at treeline (1.85 miles : 10,615'), where the forest quickly shrinks to bands of krummholz.

It clears treeline to the Battle Mountain Backcountry Campsite spur (2.45 miles : 10,956'), and up to the Chasm Lake - East Longs Peak Trail split (3.25 miles : 11,518').

The East Longs Peak Trail splits NW and moderates along the base of Mount Lady Washington to Granite Pass and the North Longs Peak Trail split (4.3 miles : 12,098’). It’s possible to peel off along this stretch and aim for the summit, however there’s easier access ahead.

Granite Pass spans a divisive ridge between the Boulder Brook and Alpine Brook drainages, with exceptional views over each. Views are arguably more interesting to the north and west, which include long sections of the Continental Divide, Mummy and Never Summer ranges.

The East Longs Peak Trail turns sharply SW from Granite Pass around the north side of Mount Lady Washington and switchbacks moderately into the high tundra.

Travel gradually levels and straightens out with an up-close look at Longs Peak and Storm Peak (13,326’), a prominent summit located just across the tundra flats (4.8 miles : 12,305’).

Mount Lady Washington is now tempting, but best to wait for a large cairn at 5.45 miles (12,625’), located a few hundred yards shy of the Boulderfield.  Breaking off too early will lead you through challenging (and unnecessary) talus.

Leave the trail at 5.45 miles and make a straight line across soft tundra turf to the rocky base of MLW. There’s a very faint boot track here that twists steeply to a small notch on the summit, somehow avoiding the worst of the sharp and unstable talus.

Scramble left from the saddle / notch to reach Mount Lady Washington and the summit log (5.9 miles : 13,281’), and right for even better views of Longs Peak.

Worth Noting

  • Mount Lady Washington's name origin is the subject of speculation. It's been thought that Anna Dickinson, the first woman to summit Longs Peak, named the mountain after Mount Washington in New Hampshire. The 'Lady' was applied later in deference to Dickinson.
  • About 68% of the trail runs above treeline. Get an early start to avoid afternoon storms, and allow extra time for the rocky descent off the summit.

Rules and Regulations

  • There's a $20 entrance fee to Rocky Mountain National Park.

"Would recommend just going to the key hole at Long's Peak versus trying to summit this 13'er. There is no direct path to the summit and you are required to scramble over large boulders to reach it. Long's peak trail as a whole is very pretty and would recommend the trek."
