Ape Cave Trail Professional Review and Guide

"“Hey Mom! It’s the secret hiding place of a slime mold!” said the delighted little boy as he descended the steps into the cave. Another child said with a gleeful smile, “Now we’re inside the volcano!” Of course she wasn’t, but these are the longest intact lava tubes in the United States, visited by 96,000 visitors each year, and representing volcanic activity of Mount St. Helens perhaps 2000 years before the 1980 eruption.

Children will be disappointed when they hear how the Ape Cave got its name: It was discovered in 1951 by members of a mountaineering club called the Mount St. Helens Apes. No, there are no Bigfoot apes found there."

We did this trail with our 2 children ages 6 and 13. They had so much fun walking through a cave. My son kept thanking me the entire day for bringing him there. make sure to bring a jacket and gloves for the little ones. My 6 year old was very cold. Average temp in in the low 40's in the cave. Also a lantern is much better than a flashlight. We had knee pads for the kids for the crawl at the end of the cave (which most people were not doing).
