Coffin Mountain and Bugaboo Ridge Trail – 06/07/2026

The X-rays on my back came back clear and the new stretches/exercises that PT assigned almost immediately improved my range of motion. Enough so that I felt up to giving another outing a try. We were heading into several days of precipitation, but there was a dry window on June 7th which worked out well for us since we had plans to attend my cousin’s daughter’s senior recital on the 6th.

For the hike Heather had wanted to find some wildflowers, and I was still limited to 6-8 miles, so we decided to give Coffin Mountain and the Bugaboo Ridge Trail a go. We’d last visited this area in 2016 (post) on July 4th.

We started our morning from the Coffin Mountain Trailhead.

We weren’t sure how many flowers would be blooming given we were visiting almost a full month earlier than on our previous visit, but the timing for the flowers is off this year due to the mild winter and dry spring. We were a little early, but there were still quite a few flowers blooming along the lower portion of the trail.

We knew that there had been a possibility of snow overnight, but we hadn’t expected any of it to stick but as we climbed, we began seeing more and more of the white stuff.

The large meadow below the summit of Coffin Mountain was covered with a thin layer of fresh snow.

The trail traverses uphill through the meadow toward the Coffin Mountain Lookout.

Heather had detoured to the southern end, so when I arrived at the lookout she was arriving at the radio towers.

I pulled my Z Seat out and sat down on the helipad and had a snack while I waited for her to make her way over.

Heather joined me and we stayed a little longer enjoying the snowy summit before heading back down. It was just before 8:30am when we began our descent and much of the snow had already melted.

The trailhead signboard in view.

Roundtrip this hike comes in just under 3-miles, but with over 1000′ of elevation gain. The snow was a fun surprise and while we were a bit early to see the wildflowers at their peak, we were not disappointed. It did appear that this was not going be a huge beargrass year though. Every few years the big meadow is packed with beargrass, but conditions have to be just right.

On our two previous visits we had road walked from the Coffin Mountain Trailhead to the Bachelor Mountain Trailhead. That is a 1.2-mile walk one-way so to avoid adding unnecessary miles to my back we drove this time.

Instead of hiking to the summit of Bachelor Mountain our plan was to take the Bugaboo Ridge Trail out to a rocky viewpoint where we hoped to get a view of Mount Jefferson and see some wildflowers. We headed up the Bachelor Mountain Trail admiring the flowers and some more snow.

The trail climbs steeply via switchback through the forest before rounding a ridge to more open terrain.

There were about a half dozen trees down along the trail, but none were too difficult to get over/around.

At the far end of the flat area we reached the junction with the Bugaboo Ridge Trail.

Trail sign at the junction. It is approximately 0.8-miles (and 550′) to the summit of Bachelor Mountain. The viewpoint along the Bugaboo Ridge Trail on the other hand was 0.7-miles away with minimal elevation change.

We headed out on the Bugaboo Ridge Trail which was a little rougher and more overgrown than the Bachelor Mountain Trail. It was however mostly free of blowdown to the view point.

The trail actually passes through several openings along the hillside with views of the Cascade Range, but not of Mt. Jefferson.

We arrived at the viewpoint for Mt. Jefferson to find it partially hidden by clouds.

We took a break here hoping for a break in the clouds and in the meantime studied the flowers in the area.

The clouds were being stubborn, but we did eventually get a little better view of Three Fingered Jack.

Mt. Washington and the Three Sisters also made an appearance.

We started back but before we’d left the open area the clouds revealed the top of Mt. Jefferson.

After getting our view we headed back. We were treated to some better views of the other Cascades along the way.

To hike to the viewpoint and back came in at 3.8-miles with approximately 700′ of elevation gain giving us 6.7-miles and 1750′ of elevation gain on the day.

This was a great hike despite being a little early for the peak wildflower bloom. The overnight snow more than made up for that. By the end my hips were feeling the hike a little but overall I felt better than I have for the past few months. I still have a way to go but it was encouraging. Happy Trails!
