Getting There

America the beautiful pass ($80), Northwest Forrest pass ($30) or pre purchase a day pass ($5) before you arrive as there is no fee box at the trailhead. Hike in the Three Sisters Wilderness with a great view of Three Creek Lake. From the Three Creeks Lake trailhead, follow a winding switch back single track trail up the mountain and out of the tree line. This tops out on the "Tam McArthur Rim" with a great view of Broken Top Mountain and the valley below. You then hike along the rim through a snow field (at least into August) and onto McArthur Rim at an elevation of 7732 feet. From here you have a great view all the way around.

US Forest Service

Best time to experience this hike is early August when in most cases the snow has melted. The road from the town, Sisters to Three Creek Lake, is mostly paved except for the last mile or two. The trail is rocky, dusty, and dry. There are no creeks along the trail so bring plenty of water. Don't forget sunblock. The views are spectacular so also bring your camera. There are some steep drop-offs, so don't let young kids roam unattended.

Follow Hwy 20 east from I-5 to Sisters, Oregon. Take a right on Elm Street which turns into Three Creeks Lake Road as it leaves town. Follow this road till it ends at Three Creeks Lake. There you'll need a "wilderness pass" to park at the marked trailhead called "Tam McArthur Rim" trail. There is a port-a-john available. This point follow the single track up the hill. After the hike you take a swim or soak in the lake which has a nice "beach" area.

HikingGreat!

oh man, this is a beautiful hike. I didn't see any trash on the trail whatsoever - good job everyone! you park on the street by the trailhead which is right by the lake. beautiful hike up, watching the lake get smaller as you get higher. a few steep parts, but getting up to the top and looking down at the heart-shaped lake where you started, now 1200ft below you... worth it. so worth it. beautiful views all around. popular trail but we had the top to ourselves.

Trail is in good shape and very popular. It’s a pretty steep climb most of the way. Towards the end you’re walking along the edge. Little shade so plan accordingly. Amazing view at the end.

Great trail and views. I did this last week on Saturday. Got a start around 9:30am. Definitely start early if your wanting to not be too crowded on the trail. Not a difficult trail and is kid friendly as long as you keep them close at the top. There was a rock slide while I was at the top of the rim. We could hear it but not see it. Sounded awesome! Trail ran a bit on the way down but started getting too busy. Lots of other people wearing masks later in the day. There were no mosquitoes when I did it. Also had my dog with me.

Visited here Monday 7/20/2020, arrived at 1:50 am, there were 9 cars. There is no parking area for this TH, you just park on the side of the road. No bathrooms here either unless you drive to one of the campgrounds.no handicap parking and not handicap accessible. Might be ok for young children there are steep drop offs at the rim and on parts of the trail, as well as some rocky areas of the trail close to the TH. Trail is in good condition. Make sure you have an America the beautiful pass ($80), Northwest Forrest pass ($30) or pre purchase a day pass ($5) before you arrive as there is no fee box here. Make sure you also have a map of the area. No cell reception at TH. Road in is gravel, potholed, rocky and washboard, any car can make it with cautious driving. Had the rim all to ourselves for Sunrise. Beautiful Sunrise up there. We continued on to see if we could get to no name lake. Make sure you have a map of the area.the trails can get a bit confusing. At one point you have to scramble over boulders. There are 2 snow fields before broken hand that are not hard to pass, the 3rd snowfield before broken hand is steep, you can go around it or cross it. Might need micros. The snow was pretty soft when we were out there. We saw a backpacker before the scramble camping in the middle of the trail. At broken hand there is a large, steep looking snowfield to get to before no name lake the access to snowfield looked a bit sketchy. My friend and I checked out the trail that goes around the east side of BH, but it ends with trees smashed up to the rock wall and we did not feel safe getting through with our big packs on. We decided not to cross the snow field as my friend was low on energy, so we turned around here. Bring sunscreen and bug spray. There's not much shade here and there were bugs up high (mosquitoes). Bring plenty of water as well. Think we saw 30 people total most of them at the rim or heading up to the rim. Got back to our cars at 1:30 pm and it was busy. Lots of people enjoying the lake on a hot day. 10.35 miles w/1816ft Elevation gain. Campgrounds were open when we went.

Great hike not too long or hard. Please bring a face mask, it’s really not that hard to do. Lots of cars / people at the lake and really busy trail with a lot of people without masks on. Just bring one for when you pass people. Was really crowded up at the top too

Second time hiking this trail today. Lots of purple-ish flowers at the beginning. Views are always amazing. Started my hike at 5am, luckily I did, there was a line of cars heading up there as I was leaving around 8ish. I would say a good trail for the intermediate hiker.

Great trail! Well marked and easy to follow. A few super steep pitches but the view at the top was worth all the effort! It got pretty hot and crowded by the time we got back to the truck just before noon - an early start will be beneficial.

Very busy trail today, but not surprising on a blue sky, weekend day. I will never tire of the 360 view from the top...spectacular!! Fellow hikers were wearing masks and/or observing distancing - thank you hikers! Little if no bugs. This trail offers little shade so plan accordingly.

Great trail - only saw about six other people. Beautiful views at the top. Took about 2.5 hours out and back, stopped at the top view and didn’t go out towards Broken Top. I had 6 miles according to my watch.

Went to trail run this bad boy- definitely ended up mainly hiking up and running down. One of the more crowded trails I’ve been on in a while but cool views from the top

Spectacular view at the top. 360 degree vista with many mountains visible and pretty lakes below the 1000ft cliffs. A safe trail, steep in places. One small patch of snow and very few mosquitoes. Beautiful flowers blooming among the volcanic rock.

Views were amazing! Went off trail a couple times so glad I was using AllTrails so it would let me know when I went off. Some mosquitos but made up for it with the TONS of butterflies.

Trail was awesome! Still a little bit of snow at the top but no problems with hiking boots. Mosquitos will get you if you stop but aren’t so bad as long as you are moving. Trails can get confusing but ultimately lead to the same place.

Great hike. Went from Tam McArthur Rim trail to No Name Lake below Broken Top. Clear trail to Tam McArthur but lots of snow on the non-maintained trail. It is hard to follow to the lake if you haven't been this route before.

Hikes this yesterday (Saturday) and it was amazing! Not crowded at all. Some snow in certain places but can easily be walked over. Continued going to broken top and there were more snow patches along the way. No snowshoes or spikes used. Only ones on the trail at that point. Didn’t go all the way to broken top because it was getting late and we wanted to stop on the drive home and grab food/ beer. Were only maybe a mile or 2 from broken top
