How much does it cost for a visitor to spend the night?

I believe Harley Smith is right. If not, it might say on their website. And if not there than I'm sure you could call them and find out. Soo worth it! That's for sure!

If i remember correctly, $10 for a day pass and another $10 to stay overnight so normally about $20 a night. Could have changed but thats what it was a few years ago.
