Awesome !!!! Lower caves get lame because of the crowds but still cool! We did upper and was less crowded and more adventurous. We brought our 7 year old and she did great!. UPPER CAVE IS NOT HARD! Group sizes (10+) were the only problem. If u hike here in WA often u will be fine! Some boulder scrambling and balance is all that is needed! Pro tip: bring head lamps and gloves... ur welcome! Those who rate this 3 stars or below simply do not belong here. Enjoy! Please remember that this isn’t a factory outlet!
