Here are the unforgettable adventures you can experience. There are activities you can pursue for a day, a week, or a month. Whatever your inclination may be, the pay-off is in the remarkable regenerative power of a classic river trip, a cattle drive, an Indian ceremony, or an archaeological dig. New Mexico offers thousands of miles of maintained trails for you to hike, bike, and ride on horseback. If you're a water-lover, a river trip might lure you into a canoe, kayak, or whitewater raft.
