Flagstaff Lava River Cave is actually named simply Lava River Cave. Unfortunately there is a second popular cave of this name in Deschutes National Forest in Oregon. As a result, and because of the nearby city of Flagstaff, it is generally called Flagstaff Lava River Cave. We will do the same to avoid confusion.
The lava tube has a length of about 1,600 m and there is no second entrance. Visitors have to return the same way, the visit has a total legth of 3,200 m. The entrance is the most challenging part of the visit, as it includes some climbing, stooping and crawling. The rest is almost horizontal walking. Most visitors do only the first 1,200 m of the cave as it becomes more narrow to the end, which takeas about 45 minutes.
