The upper cave offers some cool scrambling opportunities on boulder piles. The amount of feces that looked and tasted like it came from a human was disheartening but not a bad trail otherwise.

This cave is super fun we did the longer version. If you are scared of the dark and claustrophobic you won’t be a fan but if you want an adventure go for it. You will be climbing rocks and boulders at one point a rope helps you over a rock ridge. It’s fun!

Beautiful and relaxing easy hike for my dog and I. I will definitely go back.

Scenic. Friendly walkers, bicyclists, runners and dogs. Not fogged in as the city was below this hill. Caution when driving to the location, some drivers are flying downhill and may lose their lane; saw a crash on the way up that lead a car down the side of the hill and into a tree. Use this map to stay on the trail, since it's not well marked, and there's a few connecting trails going off of this one that won't take you directly back to the start of the trail. Parking was fine, not as crowded as the trailheads down below. Trail was a bit slippery on the wet leaves. The hike uphill was not easy, but if your up for a challenge or trying to get back in shape, it's worth it.

Driving the last ~mi on the way in is rough in spots but a car can make it, just take care. Excellent views at the very end above the treeline. All-around great hike with interesting landscape throughout.

Just did this trail today. It was my sister and my 2 children ages 11 and 8 and they loved it! We did Ape Trail that was above ground and once we got done we walked back and then went underground. I’m not sure which one we did I’m seeing a lot of posts where people say they did the Upper Cave area but crawled and we didn’t crawl at all. It was an open area cave but pitch black. I used a head flash light and my cell light and my kids had their own lights as well. We didn’t finish the cave trail due to my son sprang his ankle . The terrain is very unsteady so watch your step. Other than that it was really fun and awesome. I’m definitely coming back but more in the spring or summer time. Happy Hiking!

Did the upper caves (the challenging ones) and absolutely adored it. It gets a bit challenging in some parts but I wouldn’t consider it very hard. I enjoyed all the way.
I would recommend wearing a nice coat since the temperature is Lower downt there and definitely two sources of light (head lamp and flashlight will do) some light gloves might be helpful as well and I wouldn’t take kids younger than 8 or 9 (not only for the physical part but the fact that it’s completely dark and might find it scary)

By the way, you will need a permit in dashboard of the car to park in the lot.

Did both caves. Did this hike without hiking baby. And I would never do this with hiking baby. Helmet is a good idea for upper trail. Recommend 2 sources of light. 1 for use 1 for backup. You do not want to be in the upper cave without light. Rope is installed for 8ft climb. Was completely alone on upper cave. Honestly not smart to do upper cave alone. Learned my lesson on that one. I am a big guy and there is a lot of tight spaces. But I did it with a camera bag and backpack. Was alone for most of the lower cave.

This portion of the trail was an easy stride and full of autumn beauty! Great year round trail.

This was a beautiful hike. Great time of year. No bugs. Easy in and out. Great for kids and dogs.

It was beautiful trail inside and out. We had our 1 year old son on my husband's back and were able to do about 95% of the cave until it was just too small to crawl through with a child on your back. the terrain is a but rough for a child under 4 to walk. We loved it.

hiked this on 10/28, got .15mi from the end and turned back due to snow and thunder. once we got back down 500ft or so it turned back to rain, and by the time we got back to the rock fields we had some sun and views of Mt St Helens. didn’t see anyone else which was kind of nice. trail was easy to follow, steep in some parts, and near the top some narrow parts with a sharp drop off. if you’re planning on doing this in the next few weeks, plan accordingly.

Super easy hike. The lower cave is very roomy and it’s a clear path back and out. It was a surreal experience as a first time cave-goer. My only complaint is that a duo near us had clearly been disregarding the signs not to smoke cigarettes in the cave. Without the side of fresh air, it felt like we were walking through an ashtray most of the way.

We went to the side of the upper cave. We reached a point where it seemed like it ended, so we turned around. When we were finished and left the caves and referred to the maps...we realized we hadn’t pushed on far enough and there was more to the upper cave. Will definitely go back to try it out.

Good lights- yes...I went cheap on a headlamp and it wasn’t quite bright enough for my liking

It was quite wet and drippy in there...a raincoat was nice to have.

Good, sturdy shoes. The ground is quite uneven.

didn’t expect to do this underground cave today because we didn’t have proper lights. we were just going to hang out by the entrance to take pictures, but got so excited and amused by the scenes that we decided to carry on the upper (more difficult) trail using our iphones as lights. highly suggest using head lamps as you want your hands free. it’s flat rock at time, but there are a lot of boulders you need to climb.

i liked entering through the main cave entrance and taking the ground trail back to the parking lot. if i did it vice versa i would’ve probably been more uneasy taking the cave back.

it was my first cave experience / hike, but overall, i highly recommend.

Great hike with beautiful forest scenery, moderate elevation gain, and rewarding views from the top. It took us about 3 1/2 hours total which included a short walk on the Loowit trail at the top and a lunch break. You start off in a rock field, then most of the trail is through forest, and towards the end the trees thin as you walk through loose gravel. The uphill section wasn’t too steep but still tired us out. Bring lots of water. We veered off the trail at one point and used the All Trails app to get back on track. Really helpful.

great trail, but I ended up parking at Firelane 15 (about half a mile before the trailhead) because I couldn't easily find the start to this trail. I hiked Firelane 15 (blue trail on the left, on the map) until it connected to Skyline, and then just looped around from there. It took me an hour and a half hiking at a steady pace. Pretty empty (I went on a Tuesday at 3:30), and peaceful. Good signage.

I loved everything about this hike. Great views at the start and at the finish of the hike. We went to the Loowit trail and headed right for a quarter mile or so. Beautiful views of Hood.

This a nice, mostly flat, gravel path along a somewhat dry lake. Much of the path is behind neighborhoods and houses, but it isn't loud or anything. It is a nice running path, but I wouldn't really consider this a "hike". There are bathrooms and water fountains at both ends, which makes for a nice halfway stop.

Very beautiful. Not too many people for a gorgeous Sunday afternoon. I want to go back and walk all the way through to the riverfront.

Awesome experience! I’ve never done a subterranean hike and this was absolutely amazing. It wasn’t too crowded today. I went al the way back on the lower trail until I belly crawled to a point where my brain said enough! I did a small portion of the upper trail as I soon realized my knee injury didn’t approve. I will return and finish that tho. Again. Amazing! But please please please bring a headlamp or flashlight. Saw a few iPhone users and it just didn’t cut it.

Extremely easy hike as most of the trail was paved. The bridge and the water is beautiful and we definitely enjoyed it as a more leisurely hike.

Beautiful trail. Definitely recommend hiking poles, it was a little slippery at some places. Watch out for a steep incline almost half way through the trail.

Beautiful and nice variety!

Kids had a blast. My kids are younger so we stuck with the lower caves. But, I would love to come back at some point for the upper section. Definitely worth while for everyone to explore. Bring good lights and back ups.

Not an overly challenging hike, but very peaceful, fairly well maintained in most areas, and a good view of the river by the end!

You can just go rogue in the caves with a headlamp it was absolutely sick

Great Sunday morning trail for running. Plum tree on the way was an absolute delight. Pets on the trail are fun to interact with - always tempt me to get one !!
