Helen H. Richardson, Denver Post fileA trio of snowshoers make their way along the trail toward a 10th Mountain Division Hut outside of Leadville . With snow flying in Colorado’s mountains, an off-road trek can reward those who make it with stunning views of frozen lakes and waterfalls, slopes that glisten in the sun and the deep hush of wilderness. But an enjoyable experience isn’t likely if each step is a struggle through deep snow. Enter snowshoeing, which is among the fastest growing winter sports in the world, according to the Winter Wilds Alliance. “If you can walk, you can snowshoe,” said Alan Apt, author of “Snowshoe Routes Colorado’s Front Range.” “It doesn’t require special skills like skiing does,” Apt said.
