There's so much to love about the little streams and falls that cross so many PNW trails—from the impressive roar of cascading water to the refreshing aromas stirred up in the churn—but I think my favorite thing is the noticeable dip in temperature as I approach the stream. It always feels like the air on the trail is at least a degree or two cooler at the water, and that's a welcome shift on a strenuous hike or trail run.
