Hiked the loop clockwise starting from the Green Lakes TH last week. The entire east side is snow-free from South Matthieu Lake until a good way up the climb to Green Lakes pass. The PCT is open again after the fires, but still under a lot of snow. We were only the second set of tracks, so if you hike it this early, bring a good GPS.

Beautiful, though!

A few friends and I backpacked this loop last August. We entered at the Devil’s lake trailhead and proceeded counter clockwise from there. We made it as far as camp lake which is a amazing side trip and worth the extra distance. Unfortunately, we were diverted from there due to a large wildfire north of Camp Lake. Rangers had closed the entire west side of the loop and were rerouting PCT hikers east and then south to avoid problems. We ended up circumnavigating Broken Top and cut the trip short. I will most certainly be going back to finish this loop. Be sure to secure permits for the Obsidian area in advance of your trip, they’re limited.

Loved Three-Sisters- although this trail is not 35 mi- it is 45-50 miles depending on your entry point. I hiked clock-wise over 3 days 3 nights beginning at Pole Creek- there is no camping in the burn area at Pole Creek until you reach your first unnamed lake. There was no campfires allowed in Deschutes when I was there- which was not long after the big fire. This may have changed but I would check before going. Green Lakes was amazing, I went swimming in the water and spent plenty of time enjoying myself there, as I suggest to anyone taking this loop! Obsidian Falls was beautiful as well, but again- you can't camp here without special permits. Collier Cone was a long ascent and had limited water- but we never ran out. Overall it was amazing and 10/10 would return.

This was a great loop hike. I would rate it in the moderate category rather then easy. I guess it would depend on how much time you have. Plan your trip carefully as there is no camping in the burn section.

Nice loop trip. I went counter-clockwise. There's no camping in the burn area on the East and Northeast parts of the loop, so be prepared for that. There's no water in the 6.1 miles between Matthieu Lakes and White Glacier Creek. Camped the last night at Sister's Mirror lake, which was lovely.

One of the best backpacking areas that I have ever seen. You cannot have fires at Obsidian Springs, but camping nearby is a great idea because the water is the best I've ever tasted and doesn't need to be filtered! Absolutely beautiful every step of the way.
