Mammoth River Adventures 8883 U.S. 12, ID 83539

"What a most wonderful team! They keep everyone safe, happy, and relaxed. So professional. Never any worries with Mammoth. One of the best highlights of the year is to experience the Lochsa with this sweet group of guides. Their aim, to share fun and joy of this most fantastic River with everyone . Thank you!"

"I have rated the Lochsa many times with other outfits, so I speak with experience when I say this is a fabulous outfitter! Friendly, professional, knowledgeable, safety oriented, kind, fun, and organized. Gear is new and in great shape. Lunch was really good. Really nothing but high marks for a wonderful day."

"This trip was incredible. It was my first real white water experience and our guide Austin knew the river like the back of his hand and had full confidence the entire time. Not one time during our trip I felt uncomfortable or worried about the lines he took. We got through the rapids with no swimmers in our boat. Suck a thrill and a great group of professional guides who love to have fun and share their passion for this mighty river. Will definitely be returning to them. 11/10!"

"Best guide company on the Lochsa! Book this trip now. Great customer service, great gear and equipment, professional guides, awesome fajitas for lunch!!!
