Hamilton Creek is an interesting adventure flowing out of the mountains in North Bonneville. We accessed the creek via an abandoned rail bed that had several washouts on the way up. We hiked about 4 miles up and put on the creek at a steep section of whitewater. In hindsight we should have gone up a little further to get to more of the steeper rapids. The rest of the creek is still a mystery. I have wanted to check the upper section since this trip, but haven’t made it back yet. This roughly 4 mile section down to the Columbia River offered a fun adventure with some unique whitewater. We tried to run in in the winter and ended up with low flows. Spring would be a much better option.
