VAIL, COLORADO
Vail's kids programs cut this megaresort down to a manageable child-size. With three locations, the Small World Playschool offers slopeside sitting for infants and toddlers. Vail's ski and snowboard instruction programs, headquartered at Lionshead and Golden Peak, are tailored for 3-year-olds through teens. Mini Mice is for potty-trained 3-year-olds, Mogul Mice for 4-year-olds to kindergartners, and Super Stars for children who can ride lifts and are mountain skiers. Kids 7 to 12 can take ski or snowboarding lessons. For the whole family, Vail's Adventure Ridge, accessed by gondola (free in the evening), has ski biking, snow tubing, ice skating, laser tag, and more, which all adds up to a matchless arrangement of family entertainment. Plus, a chaperoned evening at Adventure Ridge is designed to give parents some time on their own.

Special for kids: Vail's ski-through theme parks for small children are as imaginative as they come, while snowboarders love the terrain features and half pipes. Vail's all about catering to the kiddos with children's trail maps, kids-only rental shops, phone lines dispensing kids' and teens' activity information, and several kids-only ski and snowboarding shops for gear and clothing. There's also a children's snowmobiling racetrack, which is designed for mini-­snowmobiles that travel at a kid's pace. SKE-Cology, developed in cooperation with the Colorado Division of Wildlife and U.S. Forest Service, teaches youths about the environment while exploring mountain trails.
