We chose Hyak based on Trip Advisor reviews and we were not disappointed. We had travelled over 3000 miles to vacation in the Pacific Northwest and white water was on the "to do" list. Sophie was our boat Captain and Katie was the bus driver. We did not get to know the other guides, however, Sophie and Katie were excellent. I felt we were in very capable hands with Sophie. My husband and I (late 40's) and our teen sons (17,15) were exhilarated at the experience. The river was running very high and the water was frigid (2deg. C,) but the adrenaline kept us from focusing on this. At the end of the trip there are warm showers to warm up and clean up in. I can not wait to raft again!
