We'll be taking the standard approach from the west (Pinedale, Wyoming).

Trip begins at trailhead.

Elkhart Park Trailhead to Titcomb Basin:

-> 40 miles roundtrip with approximately 9050' cumulative elevation gain.

This route has long been considered the main standard approach for Gannett Peak, although the Glacier Trail approach from the east has been gaining popularity during recent years. The western approach is a well-traveled route full of spectacular scenery and views.

The necessity to climb over Bonney Pass (also known as Dinwoody Pass) requires an elevation loss of approximately 1200' during the approach to Gannett Peak, which of course becomes an extra elevation gain of 1200' when returning back to camp from the peak. The extra mileage, gains, and losses on summit day can sometimes double-up the time required on that day, when compared with the eastern standard approach.

Trip Itinerary:


We will plan with an extra day in mind, to account for a weather day if we have bad weather for our planned summit day.

8/17 Drive to Pinedale Wyoming, Hike the afternoon to either Barbra or Hobbs Lake 5.5-6.5 miles, make camp.

8/18 Hike the remaining miles (~9) to Titcomb lakes, make camp.  Do some reconnaissance hiking beyond camp towards Bonney pass if time permits.

8/19 summit day with alpine start, ascend Bonney pass and drop down onto Dunwoody glacier and up gooseneck glacier to the summit, return the way we came back to camp

8/20 Begin hike back, camp around senica lake

8/21 hike back to trailhead, drive back to denver

8/22 drive back to denver if weather day is needed



This is a long, difficult hike and climb so please be prepared for adverse weather, possible problems with the snow bridge, bergschrund, glacier travel, loose rock, bears, and other issues associated with an outing of this magnitude.

Will need ice ax, crampons, rope, harness, helmet, crevasse rescue kit in addition to regular backpacking gear (water containers, stove, rain gear, tent, sleeping bag, etc.).

Safety will not be compromised! We will avoid lighting, protect food from bears, and bring sufficient gear to protect against rain and adverse weather.
