Big Lost Campus

The Big Lost Campus, home to IBC’s 5th-Grade Outdoor Adventure Program and a Mountain Adventure Tours mainstay, is situated on 12.5 pristine acres of land overlooking the Big Lost River, just 45 minutes from Ketchum, Idaho.

Founded in 2005, the Campus is continually being expanded to better serve its purpose of connecting individuals, the community, and the environment thanks to the support of generous donors and volunteers.

With unique examples of sustainable and responsible buildings in the high desert set up to host and welcome students of all kinds, the Big Lost Campus is where it all started. 


Our property is set up to accommodate large gatherings of people for retreats, seminars, workshops, festivals, camps, or simple getaways to recharge your mental, spiritual, and physical batteries in the Idaho mountains.

The upper property features two yurts fully equipped for sleeping as well as one adjacent to the kitchen building. Grab a bite to eat at the shaded picnic tables or reunite around the firepit to unwind from the day and roast s’mores.  True to its name, the Cottage is a cozy building equipped with couches, armchairs, and a queen-sized bed. It neighbors the newly completed Love Bungalow, a smaller building built entirely with innovative hemp materials, in line with Idaho BaseCamp’s dedication to environmental responsibility.

Our central hub and the focal point for most activities is the Borah Basin Building (BBB). Designed with love by Hempitecture and Living-Architecture, and built with the help of many volunteers, the BBB opened in 2017 as the first building for public use constructed with hemp in the United States.  It is created with approximately 75% recycled materials and benefits from passive solar design and solar thermal heating.

The BBB is a cavernous and light-filled community space  purposefully intended for many uses; with full-service bathrooms equipped with hot showers, it is a perfect location to hold meetings, seminars, workshops, or simply gather away from the elements. When the weather is willing, step out onto the deck and into  the hot tub to soak under the stars!

The lower property features extensive woodland with whimsically-fashioned signs leading along trails and bridges to the Beach Cabana, a gathering space equipped with a kiln and BBQ station for long summer nights by the Big Lost. With a number of primitive campsites available through the property, all a stone’s throw away from the river, the lower property will open up your imagination to play, explore, swim, or simply hang a hammock and rest from a day of activities.
