Strapping a board (or boards) to your feet not your style? Prefer the uphill trek? Hiking or snowshoeing is a fun date idea. Both options will provide a vigorous workout, with ample time to talk and gorgeous views. Go above and beyond by packing a small picnic in a backpack. Bonus points if it’s cold and you remember the flask of whiskey—or if you’re up to carrying it, a bottle of wine.
