Backpack to the Base of Mt. Thielsen

Oregon Mt Thielsen Trailhead

Added by Talia Touboul

  • Stunning 360 Degree Views From Mt. Thielsen to Diamond Lake
  • Access to Windigo Pass and Top of Mt. Thielsen

The Trail begins at Mt. Thielsen Trailhead/Sno Park and takes you up through a vast forest of pines. As you ascend, Diamond Lake will slowly start to peak through. Continue straight at mile marker 1.6 and keep an eye out for Mt. Thielsen ahead. Just before entering Mount Thielsen Wilderness around mile marker 2.9, the beautiful peak will be visible from the trail. Enjoy the rather eccentric looking forest around you. At times you may feel surrounded by Dr. Seuss plants; the beautiful summer colors and the formation of fallen trees create an environment to keep you entertained on your climb.

In the last 0.5 miles of your hike, take one/any of the many small paths on your left, which will lead you to campsites on the ridge of the mountain. There, you will have full views of Oregon’s beautiful wilderness and the base of Mt. Thielsen. You can set your camp up, but making the last 0.5 miles up to the top of the trailhead is well worth the full panoramic views of Diamond Lake and it’s surroundings.

How to Get There

Morning Hike

I would recommend taking this hike earlier in the morning because it does get hot during the summer months. Bring lots of water, and bug spray! I got eaten alive the second time I went. It's a beautiful hike which over looks diamond lake and mount bailey when you reach the top. I would say it's more of 9 mile hike depending on how far you decide to ascend the mountain. When you get to the base stay towards the left. If you take the right trail then you will be taking the PCT.

Fantastic Views and few people

This is a great backcountry hike before the snow falls. Fewer people camp at the top. Great place to get away for the weekend

This is a wonderful X-country ski trip. You can get significantly above tree line/PCT before grade and avalanche issues come into play. If you lose the trail (which you will) just continue east on an easy grade and soon you break out above tree line. I have always done it as a day trip, but would make a lovely overnighter.
