We saw this advertisement while searching or something to do for a short road trip, and would definitely recommend it for people of all ages. We used the directions and advice from other peoples reviews, and brought headlamps, a spare flashlight, sturdyvshoes,and a light jacket. It wasn't as cold as some people made it sound, but there was ice near... More

We were in Flagstaff for 2 days with my son and his wife and my son found this. This was really a different experience. It takes a little courage to get going, my wife and daughter-in law wouldn't do it. But, a couple with 3 small children were able to do it with a little patience in coaxing the kids... More

We went in, but not too far... Remember to bring jackets, flashlights and sturdy shoes.... It is DARK ! More

This was one of the most fun activities our family has done in Flagstaff. We've hiked and visited many sites in the area, but the lava river cave had just the right touch of fun and adventure for us. This is not a developed, guided tour kind of cave. This is a get down on your hands and knees while... More

Thank you for the best adventure my boys had. I'm glad one of the reviewers posted clear directions to this site, because it is quite far from the main road. When you get to the parking area ( it is not marked at all), follow the trail made up of rocks on both sides of the path until you reach... More
