Don’t worry. This isn’t what you think. Hehe 🙂
My wife and I went to the West Entrance of Pinnacles for the first time a few weeks ago. It’s less busy and a bit different from the East side. We decided on the Balconies Cave Trail. A little short but still pretty cool.
The caves aren’t always open due to sudden floods. Also, the Bear Gulch cave is home to a colony of Townsend’s big-eared bats as they rest there in winter and raise their young in the late spring and summer. They open the cave partially throughout the year. However, they open the whole thing for one week sometime in October. I’ve done it. It’s pretty cool.
The Balconies cave is a bit different and seems to be open year round weather permitting.
