Book in advance using the online booking & payment system. We encourage guests to book-ahead to guarantee spots. Online booking closes 1 hour before each tour's departure time.

Last minute guests who want to book within 1 hour of tour start time should call for space availability and payment options. Please do not show up without confirmation! We do not operate the tour without advance bookings, plus we don’t want to disappoint if the tour is sold out! Last minute bookings are cash-only in the exact amount. Guides do not carry cash and cannot make change. For security purposes, we are unable to accept credit card payments over the phone or in-person at check in.
