Gives you the middle of nowhere type of feel out here - this was a happy accident for me on the way back from an inaccessible trailhead. First mile was great & then the snow get super thick (should have brought my snowshoes)! Some really pretty views even if you don’t go all the way!

Off the beaten path in a great way! About 90 minutes from Washougal to the trailhead and last 7 miles to the trailhead is a windy gravel road. Trail is very nice. No one here on a holiday weekend even. The views of the valley, Mt Hood and Adams can be beautiful on a clear day. Unfortunately surely today the fire haze made for limited view of the mountains which is unfortunate. Will definitely come another time on a clear day.

Great trail! A bit over grown so I’d wear pants next time. The views are insane at the top. Full 360 of rolling hills, the gorge and St. Helens

Hiked it today for the second time, first time was June 21. We wanted to take our daughter who is home for a bit. What a difference six weeks makes. Many wildflowers gone (not surprisingly) and it was very hot and dry. The top part was a bit slippery with the dry scree. Did I mention it was hot? But still a great trail.

Logging on road so it’s in great shape! Maybe a couple small potholes, but the Nissan Kicks had no problem today in all the gravel. The trailhead to old fire lookout site is only 4.4 miles roundtrip with about 1200ft gain. A bit steep and overgrown trail, but the views make it worth it. Gorgeous view of Hood and Adams today. Lots of wildflowers too. The paintbrush was stunning.

Overgrown in some areas, but overall a great trail. Steep in the beginning for over a mile. It wasn’t busy and had the most wildflowers I’ve consistently seen along it. There’s no specific “end point” it will keep going until it connects with the PCT. Totally recommend

This was a beautiful hike. I would have given it 5 stars but it was SO crowded! We hiked to Cold Springs Camp then turned around. That made it about 8.5 miles out and back. The terrain was very diverse which made it fun and more interesting. All in all it was a great hike. I'm planning to do it again in the late summer!

My fiance and I completed this hike two days ago (April 16th). To get up to the trailhead we followed the directions on alltrails. The road had some big potholes but nothing too bad for my hyundai tuscon, definitely not as bad as I was expecting. No snow on the road up. Getting to the main grassy knoll hill there was very little snow, except the last part to get up on the knoll we had to scramble up about 50 ft of snow (just wearing regular hiking boots). No snow on top of the knoll it was a perfect place for a picnic lunch with a gorgeous view of the gorge, mt adams, and mt hood. leaving the grassy knoll and continuing up the trail there was a lot more snow. We got about halfway from the grassy knoll to where the alltrails trail ends before we turned around. We didnt see a single other person on the trail, and lots of wildlife. Really outstanding hike and worth the drive up. Truly incredible views of the forest and mountains, and a lot of interesting terrain.

12/16/19 - Wow! So glad I we and that we were prepared with Microspikes and more layers. BUT.... the road to get there was a Nightmare! Truly the worse forest road I’ve seen and I usually make fun of other people’s comments about the forest road being bad and “don’t go unless you have a 4x4” because I will drive on anything BUT HOLY MOLY!! We drove in from Carson up Wind River Hwy to NF - 65 to NF - 68. The mixture of snow and huge muddy puddles completely across the road made for many tense moments of gunning it through to be sure we didn’t it stuck. Plus there was a big tree down over the road and with hardly any clearance to get under it, luckily I have a car with no rack. Now fast forward to after the hike and google maps says to go a faster route going East on NF - 68 instead of west, nervous to try to different way but it was so much better comparatively, UNTIL we came to the gate was shut across the road we had to then turn around and drive back 45 mins to the trailhead, just so we could take the same awful route. Ugh.. long day

It was great once you get to the top but it’s very hard to find where to go once you get a quarter through the trail! And it’s very hard and very elevated!

Enjoyable hike today in the sunshine with tons of late wildflowers in bloom. We only passed two other pairs on our entire trek. High- clearance vehicle recommended due to large potholes on the road in. Also recommend pants as several trail sections were quite overgrown. The turnaround point for this hike as listed is easy to miss; we overshot it because we were expecting a large overlook. Would recommend either the shorter hike to Grassy Knoll or the longer hike to Big Huckleberry Mtn instead.

The road is nice and dry now, making it much easier to navigate with just a bit of caution. I highly recommend packing a little lunch and stopping at the top to enjoy the views and wildflowers (which are still in full force). Definitely one of my favorites this time of year, particularly the views you get for the effort and length of hike. I will say there are a few areas where the trail is a tad overgrown with thimbleberries and other bushes - it's easy enough to navigate but if you wear shorts be ready to get some little scratches on your legs. Plenty of native bees (they won't sting you) around, as well as some flies and mosquitoes but not bad.

Road in from Willard is clear of snow- there are potholes so just drive reasonable and you will be fine. Flowers just starting to open up in grassy knoll. Peaceful hike with few other hikers.

Take a capable vehicle to this trailhead. I repeat; take a capable vehicle to this trailhead. I took a Prius. I thought for sure I was going to wreck my Prius getting there. The road is so bad in places that it looks like a motocross track. Expect 10ish miles of uneven, overgrown, single lane, gravel roads-- with countless supersize potholes. By the time I made it to the TH, I noticed a storm rolling in so I got back in my car and left. I didn't even get to do the hike. There was no way I wanted to try driving that road when it's wet and muddy. The hike seemed lovely. Maybe I'll be back one day when I buy a different car.

This trail was great. There were tons of great views. The road to the trail head was a bit sketch but my 96 honda accord with barely legal bald tires did fine. Not a lot of foot traffic on the trail which was fantastic. The difficulty did not seem to be as hard as advertised.

Absolutely breathtaking views! Seeing Adams and Hood from the grassy knoll was totally worth the intense hike up. It is a little hard to find but don’t give up! Keep going on the gravel road all the way and you will finally see a sign for grassy knoll!

Definitely challenging trying to find the hike via the forest roads, and you definitely need a good car to get over those gravel road pot holes. The hike was absolutely gorgeous. Amazing views pretty much the whole way and beautiful wildflowers. Really challenging right off the bat but so worth it

Hiked this trail 2 days ago - strenuous but worth the effort! Beautiful views of Hood, Adams and St. Helens. The wildflowers provided a pretty landscape and included larkspur, phlox, daisies, and mini glacier lilies. The pot holes are numerous once you leave Bear Creek road and cross the creek. We saw only one snow bank and it was to the side of the trail. Encountered only one other person on the hike. One of our favorites!

Beautiful hike! The gravel road was a bit tough with some major pot holes, so be careful if you are driving a smaller car.
