Third Fork Cabin

Boise National Forest

Third Fork Cabin is a former guard station, first established in 1906 as Station 10 and renamed Third Fork in 1908. A cabin was built at that time, which
existed until the site was rebuilt by the Civilian Conservation Corps in 1933. The current cabin's exterior has changed little since that time, with the exception of a metal roof being added sometime before 1984.
The cabin is available between mid-April until late-October, and is accessible by car. Many modern comforts are provided at the cabin, but guests may need to bring some additional supplies and gear for their stay.

This rustic cabin sleeps four people with one double bed and two single beds with mattresses. Other amenities include a propane cook range, table with chairs, hot water heater, indoor flush toilet, shower and propane heater and refrigerator. A picnic table, campfire ring and pedestal grill sit within the fenced yard.

A camp host is located at Antelope Campground, 18 miles east in the Sagehen Reservoir area, where firewood can be purchased.

While the water at the cabin is potable, guests should bring their own supply of drinking water as a back-up. Bedding, lighting, cookware and utensils are not provided. Guests are expected to clean the cabin before leaving.

Natural Features

Third Fork Cabin sits in a steep mountain landscape heavily forested with old-growth Ponderosa pine at an approximate elevation of 4,700 feet. Tall grasses and various hardwoods grow on the site. Small mountain streams containing native fish flow nearby, and the area is marked by unusual juxtapositions of basalt and granitic rock.

Wildlife watchers may spot elk or deer wandering through the area during dawn or dusk, as well as glimpse a bear or moose. Birders can look for a wide variety of bird species.
