In summer, you can sign up for half-day and full-day backcountry hikes, wildflower walks, morning birding expeditions, and evening beaver-pond tours. Kids can sign up for art and fly-fishing classes, and families can join the "S'mores and More" family campfire program. Adjacent to Ford Park, Vail, CO, 81657. 970/479–2291. www.vailrec.com.
