The Opal Creek Wilderness area has several phenomenal sights within its boundaries. Three Pools are an easily accessible swimming holes on the north fork of the Santiam River. There is the possibility to cliff jump from multiple locations.
The quieter side of Three Pools is the south bank of the Little North Santiam. Which is what I have photographed here. Because the water is more shallow and runs slower you will find smaller children here during the summer months.
Nine months of the year, you can hike this trail and enjoy a pleasant experience. There's a craggy rock pillar in the middle of the river, and a marvelous grotto with two mouths in the cliffs near the pillar north of this spot.
