You can book this tour via the menu on the upper right side of the screen. Click 'check availability', select a tour date and fill in the number of adult travelers. Then click 'book now'. A new screen opens which indicates the final price (including group discount if applicable). You can then pay for the tour via our online payment system 'stripe' or via Paypal express. You will receive a confirmation email. Please check your 'junk' or 'spam' email box since sometimes, our confirmation email ends up there. A few days before the tour, you will receive an email with the last information (where to meet, what to bring etc.).
