Great place to take out-of-town visitors of all ages!
Parking is a little tricky. Turn into the zoo entrance and make the first left possible. There are multiple parking lots but even if you park at the furthest one it only adds about 5 extra minutes of walking.
The trail itself is very short. It only takes about 5-10 minutes to reach the hole. As I mentioned, people of any age can do this and the view is beautiful! My wiener dogs went on their first hike here and loved it!
This is a popular site because it's so easy to get to, so expect lots of people inside of the hole.
