Garnet Mountain Lookout

Watched since 1930, Garnet Mountain got its first permanent cab (a secondhand building from Lincoln Mountain) in 1950, replaced by the current R-6 cab in 1962, now a popular Forest Service rental.

Getting there
The structure can be accessed by hiking, horseback or mountain bike on the Garnet Mountain Lookout Trail in the summer.

Overview Garnet Mountain Fire Lookout sits on the apex of Garnet Mountain, at an elevation of 8,245 feet. The lookout provides a panoramic view of the surrounding peaks and valleys. Highlights include the Spanish Peaks to the west, the Gallatin Range to the south, the Hyalite Ridge to the east and the Gallatin River Valley to the north. The structure can be accessed by hiking, horseback or mountain bike on the Garnet Mountain Lookout Trail in the summer. The 4.5-mile trail gains 2,800 feet along its path. Motorcycles and ATVs can access the lookout via the Rat Lake Trail from June 16 through December 1. During winter months, guests must plan on skiing, snowmobiling or snowshoeing up to 10 miles. Guests are responsible for their own travel arrangements and safety, and must bring several of their own amenities. Recreation Hikers, mountain bikers and off-road vehicle riders can access the same trail used to get to the lookout. Snowy conditions offer abundant opportunities for cross-country skiing and snowshoeing. Big game hunting for bear, elk or moose is a popular autumn pastime around Garnet Mountain. Facilities The lookout can sleep up to four people on provided bunk beds with mattresses. There is a wood stove for heat that can also be utilized for cooking. Other amenities include a table with chairs, basic cookware, dishes and utensils. A vault toilet is located outside the facility. Firewood is provided for the wood stove, and there is a campfire ring outside as well. Water and electricity are not available. Guests must bring their own water supply, as well as garbage bags for packing out trash. Items such as bedding, flashlights or lanterns, dish soap, extra toilet paper and first aid supplies are also not provided. Natural Features A fire lookout has existed on Garnet Mountain since 1930. The current structure was built in 1962. The lookout is available for reservation year-round. It is an excellent vantage point for watching sunrises and sunsets, or for gazing at the stars on a clear night. Grizzly bears are extremely common in this area, and gray wolves, mountain lions, deer, elk, moose, bighorn sheep and the Canada lynx also make their home here. A wide variety of bird species can also be seen.

Story

Researched 4 Oct 2026, fact-checked.

Fire watchers have worked from the top of Garnet Mountain since 1930, when the Forest Service set up a camp lookout there with no permanent building, just a crew keeping watch through the fire season.1 It took two decades before a real structure arrived: in 1950, a secondhand two-story, 9-by-9-foot frame cab was hauled up and set on the summit, a building that had started life as a Fish and Wildlife observation post on Lincoln Mountain.1,2 That 1950 cab did not stay either. In 1962 it was replaced by the structure still there today, an R-6 flat cab on a 10-foot concrete base.1

The lookout sits at roughly 8,245 feet, with sightlines across the Spanish Peaks, the Gallatin Range, the Hyalite Ridge and the Gallatin River valley.3 It is in grizzly bear country, and gray wolves, mountain lions and bighorn sheep also share the mountain.3 Sources available don't say when staffed fire-watching at Garnet Mountain ended, or recount any specific fire the lookout was credited with spotting.

The lookout was kept rather than retired outright, and like several other historic cabs in the region it was folded into the Forest Service's recreation rental program, where it has become one of the more popular lookouts available to rent.2 It was added to the National Historic Lookout Register in 2022 as US 1535.1

Getting there takes real effort: a 4.5-mile trail with a 2,800-foot climb in summer, open to motorized use on part of the route only in a limited season, or up to 10 miles of skiing, snowshoeing or snowmobiling in winter.3 The cabin sleeps four on bunk beds, is heated by a wood stove, and has no running water or electricity; it stays locked, with the door combination sent to guests ahead of their stay.3 As with any rental lookout, it's meant to be booked and visited through that system rather than entered without a reservation.

Where sources disagree

We show disagreements between sources instead of quietly picking one. If you know which is right, please tell us.

  • Sources disagree on the year it was built.

    • NHLR: 1962
    • firelookout.com -- Rex Kamstra's Forest Fire Lookout Page: 1930
    • recreation.gov: 1962

    Sources give different build years. Often one counts the first lookout on the site and another the structure there now.
