A very pleasant early-season wander in the trees, and much more enjoyable than I expected. After a brief tourist stop at Nooksack Falls in the rain, we decided to brave the showers and head out on this little riverside walk. The showers abated and we ended the trip in bright sunshine. There doesn't seem to be a well-defined turnaround point, but we reached the viewpoint overlooking the river as it emerges from its Horseshoe Bend and decided that was good enough.
The trail is in very good condition, especially the first half-km or so. There is a little shallow creek to cross which is easily done on some small logs and rocks. Beyond that there are a few patches that aren't really muddy enough to be called "muddy" - more like "squelchy", just enough to get your shoes a bit dirty. Further on, the trail has some ups and downs, a few of which are surprisingly steep; certainly enough to get you a little out of breath.
Flowers: trillium aplenty but well past it, a few good strawberry patches in flower, streambank spring beauty, fringecup and piggy-back plant aplenty. We didn't spot any orchids.
Note: most of the trailheads along the Mt Baker highway require a parking permit. It's not clear to me that this trail is one of them, so best check with the visitor centre in Glacier before setting off.
