Winner: Grand St. Bernard Pass, Switzerland
Switzerland is a great place for the whole family, because it’s easy to get around, the food is incredible, and the scenery is even better. The cherry on top: puppies! Wilderness Travel has a ten-day trip that crosses over the Grand St. Bernard Pass, home to the famous rescue dogs. The outfitter has a special permit that lets the kids hike with them for a few hours before continuing past 12,000-foot peaks and through hidden patches of edelweiss. Plus, the distances are short-leg appropriate: you’ll walk no more than five hours a day, and there’s a shuttle option if that’s still too much for the kids (or Mom and Dad).

Runner-Up: Yellowstone and Bozeman, Montana
Southwest Montana has plenty of kid-friendly activities—and almost all of them are within a short drive of great lodges. Spend a few days at the 12-room Gallatin River Lodge (from $300; grlodge.com), where families can take free fly-casting clinics, mountain-bike eight gentle miles of doubletrack through Sourdough Canyon, or raft over Class III rapids in the Gallatin River. After that, head to Yellowstone National Park, where kids can become junior rangers while learning about geysers and wolves on ranger-led hikes.
