Snowshoers should avoid post-holing—a term that refers to walking on a packed-down trail without snowshoes, which leaves large holes in the treadway. Both snowshoers and Nordic skiers should steer clear of tromping on or across ski tracks, as this can make it difficult for skiers to glide and may even cause injuries. Instead, stick to the far outside edge of the trail. If you fall, take a moment to fill in any divots before continuing on. And, of course, remember to stay on marked trails.

Most Nordic ski trail systems follow standard rating designations: green for beginners, blue for intermediates and black for experts. Know your limits and pick the trails that best suit your skill level. While skiing, navigate around tree wells—holes in the snow that form around the base of trunks—by giving trees a wide berth and sticking to groomed runs, as these are less likely to have deep snow pockets. Never cross lakes, rivers or ponds on snowshoes, even if they appear to be frozen.

Generally, snowshoers heading uphill have the right away, so be courteous and step aside to let them pass. For Nordic skiers, always go the correct direction on any trail that’s a one-way route. On two-way trails, uphill skiers should yield to downhill skiers as they have less control. If you’re moving at a slower pace, keep your eyes peeled for faster skiers overtaking you and move to the side if possible.
