Somewhat like a junior version of Rocky Mountain National Park, Mueller contains over 5,000 acres of prime scenic beauty along the west slope of Pikes Peak. The 55 miles of uncrowded trails, designated for hikers, horseback riders, and mountain bikers, provide great mountain views and opportunities to observe the park’s wildlife (including elk, bighorn sheep, and black bears). The best times to spot wildlife are spring and fall, just after sunrise and just before sunset. In the summer, rangers lead hikes and offer campfire programs in a 100-seat amphitheater. The park has 132 campsites ([tel] 800/678-2267 for reservations), with fees ranging from $18 for walk-in sites to $22 for drive-in sites with electricity; coin-operated pay showers and coin laundry are available from mid-May to mid-October. Also available are two- to four-bedroom cabins for $140 to $260 a night.
