Free parking and 10 minutes to get to the hole-in-a-rock. The surrounding area is pretty with lots of palm trees and cacti. I went today and it was pretty crowded up at the hole. People were hanging out and taking selfies. You're allowed to bring dogs so long as they're leashed. It sucks that 1/2 of the view from the hole is of the cars in the parking lot since it's not too far up. It looked like there were some spots where you could do some bouldering toward the bottom of the rock. I saw a woman do this "hike" in wedged heels and a dress.
