In the agency’s own words

Mystic Lake Cabin was built in 1930 and is currently open year-round. It provides access to a variety of recreational activities, including fishing, hunting and exploration of numerous trails. The cabin is located in a non-motorized area. Guests must be prepared to hike, horseback ride or mountain bike to get there in the summer, and winter access is by cross-country skis or snowshoes. Guests are responsible for their own travel arrangements and safety, and must bring several of their own amenities. Keep reading

Recreation

New World Gulch Trail and Bozeman Creek Trail are just a couple of the multi-use trails in the area for hikers, equestrians, mountain bikers, skiers and snowshoers. The Mystic Lake Loop is popular with mountain bikers. Anglers can fish for brook, rainbow and cutthroat trout in Mystic Lake. Hunting opportunities are good in the fall.

Facilities

The cabin has bunk beds with mattresses to sleep up to four people. A wood-burning cook stove also heats the cabin. Other amenities include a table with chairs, basic cookware, dishes and tableware. Firewood is supplied for the stove. Outside is a campfire ring and a corral for up to two horses. An outhouse is equipped with a vault toilet. No electricity or water is available at the cabin. Guests need to bring their own supply of drinking water, as well as items such as fire starters (matches and newspaper), flashlights or lanterns, bedding, extra toilet paper, first aid supplies and dish soap, which are also not provided The cabin will need to be cleaned and all trash removed prior to leaving.

Natural Features

The cabin is tucked into a stand of pines near the southeastern shore of Mystic Lake, at an elevation of about 6,400 feet. The landscape surrounding Mystic Lake includes meadows that fill with wildflowers in the summer, as well as evergreen forest and the peaks of the Gallatin Range. Visitors may spot one of the resident black or grizzly bears, moose, elk or mule deer. Several bird species also inhabit the area.

What the agency tells you

Rule

The cabin remains locked; a combination lock code will be contained in the reservation confirmation letter/email

Rule

Directions and Access: Mystic Lake Cabin is not accessible by motorized equipment including E-bikes. (See below and refer to the Motor Vehicle Use Map) From Bozeman, MT.: Drive south on S. 19th Ave. for 5.1 miles to Nash Rd. Turn left (east) onto Nash Rd. Drive 1.7 miles to Sourdough Canyon Road, turn right (south), and drive for 0.9 miles to the Sourdough Canyon Trailhead. From the Sourdough Canyon Trailhead travel south on Trail 454. At mile 5 just before the bridge you have two options: 1. Before the bridge turn left onto the Mystic Lake Trail 457. Follow this single track trail approximately 2.8 miles to Mystic Lake. Cross the outlet of the lake to find the cabin up the hill on the south end of the lake. 2. Cross the bridge and go left at the junction to stay on Trail 454. Travel this old roadbed for another 5 miles to the cabin (this is the recommended winter route). In the winter, Trail 454 is a groomed cross-country ski trail and is closed to all bicycles and wheeled vehicles. Many stock users prefer accessing Mystic Lake cabin via the New World Gulch trailhead at the end of the Bear Canyon Road. From the trailhead follow New World Gulch Trail 50 ~4.5 mi. to Mystic Lake Cutoff Trail 430. Turn Right onto Trail 430 and continue 0.75 mi. to Bear Lakes Trail #53. Make a right and continue another 0.5 mi. to trail 454, where another right will take you down two wide, vehicle width switch-backs to the cabin within 0.25 mi. This route tends to have less bicycle traffic than the sourdough route, though they may still be present.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 1 of the 1 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.

Measured shade is NLCD Tree Canopy Cover 2024 (USDA Forest Service / MRLC) read at the site’s own coordinate, 27% canopy or more, and only for the sites the agency gave no Shade value. It never changes the agency’s own shaded count beside it.

OpenStreetMap has no toilet mapped within 1 km of this campground, so no site here carries a toilet distance. That’s a gap in the map, not a finding about the campground.

Write to somebody who can change it

Two offices, two different asks. The draft to the agency asks it to set aside a published share of the sites here for whoever drives up. The draft to Congress asks why that share is zero and presses for a published minimum at the campgrounds it funds.

Read the draft, or change the wording

For the camper who turned up, or tried to book, and couldn’t get in. Every draft is written from this campground’s own record (its agency, its unit, its site count and its own weekend) and the buttons above copy whichever wording is selected here.

To Ryan K. Zinke

Asks them to put the question to the agency in writing, and to press for a published minimum share of walk-up sites across the campgrounds they fund.

Subject Walk-up camping at Mystic Lake Cabin, Mystic Lake Reservoir Water Reserve Withdrawal, Montana

Dear Ryan K. Zinke,

I’m a constituent in Montana’s 1st district. I tried to camp at Mystic Lake Cabin, Mystic Lake Reservoir Water Reserve Withdrawal, Montana, and couldn’t.

All 1 sites at Mystic Lake Cabin are reservable, and the agency's own record lists none held back for somebody who drives up. On Saturday, October 17, the one site recreation.gov was offering there was already booked.

1,623 of the 7,647 federal campgrounds in this country still keep at least some sites for whoever arrives first. Mystic Lake Cabin keeps none, and that’s a choice somebody made rather than a rule.

I’m not asking you to run Mystic Lake Cabin. I’m asking you to put it to the U.S. Forest Service in writing: why is the share of first-come sites there zero, and what would a published minimum share cost? Please press for that minimum at the federal campgrounds you fund.

The people who open these campgrounds, collect the fees and keep the water running are seasonal positions. At GS-5, base pay plus the government's own 36.25% benefit factor, one costs about $47,414 a year. One percent of the $13.3 billion the USS Gerald R. Ford cost to procure would pay for about 2,800 of them for a year. Both figures are the government's own (a Congressional Research Service report and an OPM pay table), and I’m glad to send them.

How we know

every fact on this page, and where it came from
Right now: recreation.gov is offering sites on 30 of the next 30 nights, which isn’t something a closed campground does.
Cell signal: the Forest Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
