Greig's caves was a curiosity of mine. I had passed several signs but did not expect much. I followed the signage way down a sinister dirt road to what seemed like a legitimate park. There was a booth with a polite attendant who informed me that there was no debit or credit for entry. Damn my cashless existence. After scrounging the car for change I came up with the $10 entrance fee and was handed a flashlight and a warm welcome. Down the hill, around by the water and back up. That's it.
