Saddle up on a Tennessee Walker for a smooth trail ride through the Cerillos Hills Historic Park, south of Santa Fe, where dusty arroyo trails that wind up juniper-dotted knolls, past 100-year-old gold mines. Two- and three-hour trail rides are offered, including a sunset ride most evenings, and once a month, a full-moon ride. The horses are exceptionally well-mannered and you'll get to run them.
