“Boundary Expeditions is a world-class facilitation all around, on one of the finest rivers I have been on no less. Eric and his crew exceeded all my expectations.

First time on the Middle Fork and we are still in awe. Beautiful scenery, friendly guides, and fun whitewater! Camping next to the river and traveling by raft is something everyone should experience. We caught our first West Slope Cutthroat on a fly rod and it’s now my 14 year old son’s favorite sport.
