Bunsen Peak Trail Description (1K4) Light Traffic

Short and sweet! This is a great early morning or late afternoon hike that doesn't take long but delivers a stunning panorama of Gardners Hole, Electric Peak and the Gallatin Range.

If you're pressed for time and are looking for hike that will take just a few hours Bunsen Peak is ideal. It's 4 miles to the summit and back, and in a short time you can climb above the surrounding landscape rather quickly. There are extraordinary views from most points along the trail and once you're on top of Bunsen Peak you'll be treated to the open expanse of Swan Lake Flat and Gardners Hole. The rugged Gallatin Range provides a picturesque backdrop for any photographer. (See photo tips below)

From the parking lot the trail heads north up the lower slopes of Bunsen Peak. On your left you'll have a birds-eye view of Golden Gate/Glen Creek Canyon with the Hoodoos and Mount Everts visible in the distance. The 1988 fires impacted this area significantly and you'll see the effects of this first-hand as you move through areas of standing dead trees (widow makers) and the newer and younger trees.

At just under a mile the trail swings back to an open south facing slope with vistas of Swan Lake Flat and the Gallatin Mountain Range. Electric Peak dominates the view to the west with Antler Peak and Quadrant Mountain extending to the southwest. At this point the trail heads north again into what I call the dead zone. This section of trail is filled with numerous standing dead trees and has a very 'Tim Burtonesque' feel to it. From here you can peer through these gnarled trees towards Terrace Mountain, Sepulcher Mountain and Golden Gate which is now directly below you. At 1.4 miles the trail makes a sharp right at a large rock formation know as Cathedral Rock. This is a great spot for taking photos of the Mammoth Hot Springs area and Mount Everts.

Now the work begins. This last stretch to the summit climbs a series of steep switchbacks and much of the trail is covered with loose talus. Pay attention here because it's easy to lose the trail in these talus sections, especially if you're taking in the views. Now head south, then north, then south, and finally north again until you're on the back side of Bunsen. As you near the summit you'll notice utility lines leading up to the peak. There is a weather station located on top but the views are amazing and if you're lucky you'll have the peak all to yourself.

Photo Tip
If you hike Bunsen Peak early in the morning the sun will be in the perfect location for photographing the dramatic eastern edge of the Gallatin Range, Swan Lake Flat and the vast open plain of Gardners Hole.

WARNING: The weather in Yellowstone can change rapidly at any time of the year. During the summer months afternoon thunderstorms are very common and there is no easy way down from the summit of Bunsen Peak if the weather changes. Temperatures can drop significantly within minutes and at elevation the wind will almost always be a factor even on the nicest of days. Start your hike early and be off the mountain by mid afternoon.
