The cave interior is pitch black: there is no other source of light in the cave. A wimpy standard household flashlight will not cut it. We bought flashlights of 200 lumens for $10 at the Walmart in Battleground and they were great. My husband is still excited about what a good buy they were! Lanterns are available for rent at...

They are dark place with nothing but tunnels you need a flashlight and if you lose your battery you are screwed. Come here with a back up and make sure you're not alone.

Well at least I've never seem such a massive or lengthy lava tube - it's over three-quarters of a mile in one direction alone and maybe as much as 20 or 30 feet in diameter. It;s totally pitch black inside - you need a high power torch or a lantern (you can hire on site) because there is a load... More

Amazing experience to walk through these caves. 2.5 miles of awesome sights. Lots of rock climbing and one spot where you climb up an 8 foot wall. This really tests your endurance and you feel like you have accomplished something great. Headlights are recommended instead of flashlights because you will need your hands. Good hiking boots are a plus. This... More

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...
