Hike A Lava Tube!

Coming from Seattle, it's about a 4 hour drive. I wouldn't say it's worth the drive just to see Ape Cave. However, it's a nice stopover place if you're in the area. After biking Ape Canyon and the Plains of Abraham earlier in the day, we decided to stop by Ape Cave on the way back home since it was... More

If you are at Mt. St. Helen's, Ape Cave is well worth the trip. We hiked the short lava tube. It is unguided so bring your own flashlight. Sturdy shoes are a good idea as well as a fleece or jacket. It was 90 degrees outside and 45 - 50 in the cave - it was awesome.

Over crowded, waiting line to go down the stairs. Smelled like poop at one spot in the cave. With $5.00 to park and multiple employees hanging around one could go on down and clean that up.

A wonderful diversion on a hot day. The cave is always cold no matter what the weather. Be sure to take plenty of light sources because it is very dark. We enjoyed seeing the cave in its natural state without the "improvements" that you see in so many tourist caves. Come prepared because it is in the middle of nowhere,... More

Good for the novice caver. Need appropriate shoes, sweater and a good flashlight. It's a constant 42* pretty easy walking with a good flashlight. The entrance starts in the middle so you have a choice to go either the upper or lower 1/2. We did the lower 1/2 and will soon return to finish the upper 1/2.

This was so cool to visit! Go early or later in the day to avoid the crowds. TIPS: *bring a flashlight or headlamp(you can rent a lantern for $5 if the store is open) *wear comfortable shoes *wear layers as it does get cool down there-we could see our breath *be prepared for rough terrain in some spots Have fun...

If you want to do something fun with the kids that is educational too, this is the place to go. It is just beautiful. It can be a little wet and slippery so be careful and wear good shoes for hiking. It is also VERY dark! But it is an amazing experience that you should not miss. You have to... More

I went here with my teenage son and it was AWESOME! Beautiful drive to get there as well as the trail getting there. As mentioned, you must bring a really good flashlight or headlamp because it is pitch black down there. We did have lamps but had to follow another couple to get through it! You do have to have...

I live near a lady whose grandfather discovered the Ape Cave back in the day. If you visit SW WA state and go to Mt. St. Helens, the Ape Cave is a must-see. There are many other attractions near it, such as, The Trail of Two Forests, the Lava Canyon and many miles of hiking trails. The trail up the... More
