Banff National Park Rules of the trail Riding non-designated or closed trails, building new trails, or riding off-trail displaces wildlife and destroys soil and vegetation. These activities are also illegal and violators may be charged under the Canada National Parks Act. Be bear aware. Cyclists are particularly susceptible to sudden, dangerous bear encounters because of the speed and silence of their travel. Be alert, make noise, slow down, carry bear spray, and look ahead. Ride designated trails. It is your responsibility to know where you can and cannot legally ride. Avoid riding during extreme conditions. Wet, muddy or very dry trails are more likely to be damaged.
