A enjoyable trip overall. Trail is manageable but not pristine and could do with some maintenance. Some beautiful segments but sadly a large portion of the trail is through burnt out forest. Views at the top are some of best I have seen in the cascades. I would agree that totally worth a trip out but not the nicest trail in the area. Road in is good quality, there were two “road closed” ahead signs but that closure must be past the trail head as I made it all the way there, driving a sedan so totally accessible.

The trail was lush, but overgrown after about 1/2 a mile. We hiked yesterday, but got hit by unusual August rain. The views were not there due to clouds. There were plentiful berries, and some open flowers, but beargrass was done blooming and almost two miles of trail was overgrown to the point that the wet foliage completely soaked us. Open areas had views of burnt trees mixed with fireweed blooming. We wore shirts and rain jackets, but I wish we had worn long rain proof pants or had better weather. I’m sure this is an enjoyable hike in dry weather, but we bailed out before i got hypothermia.

Completed this trail on 7/5. The directions to the trailhead were very clear and easy with nice signage and parking. The morning clouds burned off by the time we hit the trail, around 11 am. Everything was lush and green and we were greeted with several wildflowers. After the Olallie Mountain junction, we entered “Beargrass Central”! It was breath-taking. The last stretch to the top is a bit narrow and rocky. Watch your footing. I slipped once or twice while gazing at the expansive views. I was pretty disappointed to find the lookout structure completely torn down and demolished at the top. Other than that small upset, the views were absolutely magnificent! Three Sisters were front and center with Broken Top right next to them. To the left Mt Jefferson, Three Fingered Jack, and Mt Washington. To the right Mt Bachelor. We enjoyed our lunch and time alone for about 30 minutes before heading back down. Ran into 3 parties on the way out. Beautiful day, beautiful hike, happy hiker!

We hiked on July 2nd. The Bear Grass is abundant and beautiful right now. The meadows are days from blooming, but not many right now. But beautiful wildflowers in the woods and on the exposed rocky hillside near the top. There are many blown down trees, but most have a work around trail. Lovely views from the top and the meadows will be in full bloom soon! A great hike. The road is not bad, very little washboarding. You do have to watch for the occasional pothole.

The bear grass is insane here right now. It’s growing everywhere. Couple small creek crossing that are very easy to cross. A little overgrown in a few sections. But still amazing

11/17/19: IMO, this hike is worth doing if you regularly access this area. If you are visiting with limited time, there are more favorable hikes. I accessed the Olallie Trail via the Pat Saddle Trailhead. It is close to 14 miles of curvy, (often) washboard gravel on road 1993. You need to watch for rocks, potholes and blind corners on your drive. The road is not necessarily bad, and most passenger cars can make it, but it takes time. Besides being so far out, the hike is through some burn area. This area is home to some amazing old growth forest, but this trail doesn’t always highlight it. The lookout itself is dilapidated (although I appreciate the efforts made to save it). It is a good climb and well marked at the turn to reach the summit. Parts of the trail are overgrown. There are some small water crossings. I enjoyed the winding hike to the summit. It is a bit exposed and rocky but doable if you just watch your step.

The road is in great shape heading up there. I was in a 4dr sedan and didn't have any issues. The trail is in good shape with a few creek crossings here and there but nothing too bad, I didn't get wet. A little stretch of snow drifts on the section after the junction but it was very manageable. Beautiful views from up top. There were a few mosquitos here and there. Wildflowers are also starting to bloom.

Summit trail was a pit tricky to locate under the early-June snow when I hiked. I just followed the creeks and meadows to the ridge, where I reconnected the the southbound trail leading to the top. Big kitty cat tracks (fresher than mine coming in) were spotted in the snow on the descent. The snow melt streams, wildflower meadows, and and the views from the top make up for the burnt surroundings.

The rock slide in FR19 is still there and it doesn't sound like there is a plan for clearing it anytime soon, so find an alternative route. also, the trail is closed from the south entrance near Frissell Crossing Campground, so try to enter from the north. pretty hike, though

Did a quick overnight to Olallie Mountain. The road in is fine. I came in from 126 and took 19 down to the damn and crossed over, following 1993 all the way to the trailhead without any problem. The trail itself wasn't in too bad of shape for the early season. Some blow downs to traverse due to the fire here last year. The burn is patchy hear and there alternating with green. Views from the top were pretty spectacular as you can see the whole forest basin between Olallie and the three sisters. I'm sure this is why the lookout tower is here. There aren't many good flat spots on top to pitch a tent and the ground is really rocky making a free standing tent a better option. Quick hike with great views.

INACCESSIBLE!! there are two huge landsides 6 miles before the trail head. we went over the first.it consisted of a rockslide.huge boulders. but we made it threw alright. about half a mile up from that there is another huge rockslide at least twice the size and going over the edge of a steep cliff along with a crap ton of mud.we were very disappointed but it simply wasn't safe to go around. all the trails up that road are closed. they need to update these trails more often
