This cave is a bigger part of the cave that was found by Charles W Darrow in 1895 and it is a /4 (quarter-mile) tour.
Touring of the cave
Like I mentioned above, it is a 1/4 mile of walking and takes about 40 min to complete. You get to the end and it opens up to the view of the canyon. It was an interesting place to go see.
Of course there are pictures
Probably the best part of this was when it opened up and you could see the canyon. It was a view of what the inside of a mountain was like. If you get a chance then go and visit.
Here is a video I found on this cave
