I will second what the previous reviewer said about getting there--do NOT follow the Google directions, as one of the roads (NF-398) is impassable by most vehicles. My AWD Subaru didn't stand a chance. Instead go to the Willamette National Forest website and use those directions. My friend and I did this hike on a Sunday--started at 10:15 AM and finished around 7:15 PM (with some stops along the way at the summit and at Marie Lake). It's definitely not a trail for the faint of heart--I HIGHLY recommend trekking poles given the slippery terrain and scree. The last 1 and 1/2 miles or so comprises the most difficult section and requires paying close attention to the rock cairns and flags that mark the climbers trail (on the way down there is also the occasional spray painted rock, which I do not condone, but was certainly helpful). This final section took us about 1 hr and 45 minutes to finish, and was slow going due to the slightly treacherous terrain. However, getting to the summit felt like a huge accomplishment, and the views were gorgeous despite being slightly hazy/smoky due to nearby forest fires. After summiting we ended up taking an off-trail shortcut to Marie Lake, as can be seen in my recording. There are a few excellent camping spots at Marie Lake, and I will definitely be back to enjoy them. Overall, Diamond Peak was a fabulous experience, but be warned that it is not for beginners!

Excellent climb on 08/15/2020. Similar to south sister with 2% of the crowds. First things first, DO NOT follow google directions if coming from Eugene. It will try to take you around the east side of the mountain via summit lake. This road is not passable for most road vehicles. Instead, use the directions posted by Willamette National Forest. Essentially use forest road 21 around Hills Creek Reservoir near Oak Ridge. Definitely doable as a day hike, I chose to do it as an overnight. Hiked in and camped at Marie Lake. Then got up early to beat the heat of the day. No snow left anywhere on trail. The boulder field/sandy scree section is definitely the hardest part. Follow the Cairns on the way up. On the way down, somebody spray painted yellow dots that lead a good route down (though I definitely don’t support spray painting routes). From the false summit to the summit is a very rocky ridge line climb that offers spectacular views with some amazing bird watching. This says 11 miles, but I tracked it closer to 13. Overall, probably one of my favorite hikes close to home in Oregon.

Super awesome day to go. The trail head isn’t that easy to get to and can be slow but was doable from the north. The trail doesn’t mess around at first with a little steep mixed in then gets flat to the PCT with a little downhill.. once you get off the PCT at the Cairns in the pics and start going up th train doesn’t mess around and is straight up up up.. felt a little like Cactus To Clouds.. once you get to tree line the trailS start and it’s basically up.. so best to just keep heading that way. After the false summit there is a little class 2 scramble on the ridge line traverse then it’s scree sailing to the top.. enjoy

Lots of mosquitoes for first 2 miles. No snow that couldn’t be avoided. A bit hazy at the top. Saw no one else except a PCT hiker.

Trip report from 7/11. Snow pretty much gone, except after the false summit. But the trail is almost completely snow free on the summit approach, so it’s not a problem. Mosquitos are just horrendous, come prepared or you will have a very bad time. Climbers trail can be hard to follow, GPS recommended if you haven’t done this trail before.

Beautiful hike. Camped at the trailhead Monday night, and started up early Monday morning summiting around 11:30am. Mosquitos are relentless right now. First two miles of the trail are pretty much clear of snow. However, once you hit Marie Lake the snow becomes a fairly major issue. Lots of snow patches make it really difficult to see a continuous trail. We ended up leaving sticks in the snow and rockpiles closer to the mountain, so we could find our way back okay. I would highly recommend having a GPS, leaving trail markers, and having a compass at this time in the year. Once we got out of the tree line, hiking to the summit was essentially a scramble up the mountain. A few routes seemed visible as trail heading to the top. Beware of the multiple false summits. However, the summit was perhaps one of the most beautiful views in the region. Saw 10+ mountains from the peak on a really clear day. Superb hike, but I would recommend doing it later in the summer when the snow has melted from the trail.

First to Review

Hiked Saturday, 9/21/19 with absolutely perfect weather. Super fun mountain to climb, but still a nontechnical hike. Followed the driving directions and hike description in William Sullivan's book,100 Hikes in Central Oregon Cascades. The road: paved FR 21, gravel Pioneer Gulch Rd and Rockpile Rd are passable by even passenger cars with a little care. TH is marked with a sign, parking area on the side of the road. The trail: Rockpile trail is in good shape, easy to follow. PCT of course in excellent shape, very easy to follow. The turnoff to the climber's trail was marked by two cairns, easy to spot. Climber's trail is relatively easy to follow on the way up, take care to note the route up after treeline in order to meet back up with the trail on the way back down. The GPS track/route on this page was spot on and very helpful. The climber's route was easy to see even close to the summit. There are a few large rock formations that one has to pick their way around, but a decent trail is currently there, and we only need to use our hands once or twice. Bit of snow was present above 8000' or so, route is currently snow free. Saw 8 other folks the whole day. One hiker came from Summit Lake, stated that the road was only passable by a high clearance pickup, in 4 low the whole time, lots of ruts, rocks, and deep standing water, and it took over an hour.
