This is a really wonderful trail if you are looking for something short. We hiked this right after hiking Murhut Falls which made a nice day in the area. The first part of the trail is mostly flat, then goes uphill steeply, then downhill even more steeply to the view of the river. There were a couple spots to look over at the river but there were steep drop offs to the swiftly flowing river to watch your step. Not too busy today, maybe 4 or 5 other cars in the parking area when we were back at our car.  

I wanted to do a quick hike before work, so I hit up a short trail that popped out on my Olympic Mountains East Map. I chose it mainly for its length (.7 Miles) and rather odd name (Ranger Hole).
My expectations were pretty mild, as I'd never heard anything about this trail. I reached trailhead at 10am, and was the only car in the lot. The trail is in good shape considering all the rain we've had, it's only slightly muddy.  Once I made it to the main viewpoint of the River, I was able to do a bit of scrambling through the trees to make it down to the beach just downstream of the Ranger Hole. The Ranger Hole is a large pool right after a small canyon that the River is forced to flow through. The color of the water here is an incredible shade of aquamarine.
This is a great hike for those who want to enjoy nature without putting in heavy miles, or for those with kids. Do be careful if you go out to the end of the trail next to the canyon, as the rocks are slippery and you could easily fall into the canyon rapids.
It would also be a great place to go swimming in the Summer, though I'm sure it gets crowded once the weather warms up.
10 out of 10, would recommend!

After a couple days of hearty hiking, opted to do this hike along with Murhut Falls, which is just up the road.

Nice little trail with an interpretive loop at the start telling the history of Ranger Finch and the area. 

Arrived around 11:30AM and only a few cars in the lot. First part of the hike is filled with huge ferns, massive tree trunks that are now nurse logs and lush green moss. There are a couple inclines along the way and then a decent, which was a bit wet and mushy, before you reach the end of the trail where there are a couple of spots with clear overlooks of the river. If you have little ones definitely hold their hands along the edge as there are no railings.

The water is rushing and an incredible  green color.

Privy is open.

Beautiful little trail to a pretty turquoise river. We drove from Everett to do a couple of short trails in the area, and arrived at the parking area at 11:30 am on a Sunday and there was one other car parked. There are no trash cans so plan to pack home what you bring. Just down the trail is a privy that was pretty clean. 

We did the Interrorem Nature Trail first. It begins by taking a left just after the privy. Huge mossy trees hang over the trail, and there are wide stumps left from trees cut down long ago. If you look at some of the pictures on the signs, you can see how much the forest has grown since it was logged. The trail is graveled with even footing, and we enjoyed this part a lot.

After rejoining the trail to Ranger Hole, we passed through groves of maples completely coated in bright green moss. It may be winter here, but it is still bright and lively. The trail climbs a bit, then descends (sometimes steeply) down to the river. The trail is a little soggy closer to the river but its all in very good shape. 

I didn't expect the river to be so blue, its hard to capture in a photo but it was very pretty. We checked out a couple of viewpoints before heading back up. We ran into a few more groups but there was still just four cars in the parking area when we returned. We clocked about 1.5 miles by skipping the Interrorem Trail on the way back.

Just did this one since it was an easy .8 on our way back from another hike up the Duckabush. Some fairly recent trail work has improved the bottom section with steps. Lots of CFUs flowing in the Duckabush after recent rains.
