We have hiked, run, backcountry skied, and backpacked the Yoho Valley.    Our favorite trail is the Whaleback Trail which runs from the top of Twin Falls to the Yoho Valley.    This bridge crosses the creek that spills over the cliffs to form Twin Falls.    Across the valley is Mt. Balfour, another peak we have explored on the Wapta Traverse.    All of the trails in Yoho National Park are A+ hiking destinations.
