An incredible mountain biking experience in a tunnel surrounded by rocks. You'll definitely push yourself to your limits here, and if you haven't found them yet, have fun! The tour takes 2 hours and covers about 10km. By the end, you'll have no sense of time or distance covered. Definitely not for inexperienced bikers.
