About the trip

Bunsen Peak & Osprey Falls

Bunsen Peak was named after Robert Bunsen, inventor of the Bunsen Burner, who studied volcanic geyser activity in Iceland. Today, we'll be climbing 1300 feet up this impressive, extinct volcano. From the summit, you'll enjoy expansive views over the Blacktail Deer Plateau, Gallatin Mountain Range, and Yellowstone River Valley.

After catching our breath on the summit, we'll descend the backside of the mountain and continue into Sheepeater canyon. Walls of columnar basalt tower above as we make our way down to the falls. Osprey falls, on the Gardner River, plunges 150 feet over the edge of a lava flow. We'll have a picnic lunch in the canyon and feel the spray of the falls, which will cool us on a hot summer day.

We'll make our way out of the canyon and complete our loop with an easy stroll through a meadow.

You can expect to be active for six to eight hours. You can best prepare for a Level 7 trip by maintaining your intense fitness regimen, trying to get your mile time below eight minutes, and hiking consistently on the weekends.


Level 7 hikes can be anywhere from ten to thirteen miles.


We will be on mountainous, exposed terrain and steep, uneven trails. Most hikes will require not only hiking boots but also additional gear like hiking poles and headlamps.
