Set amid the colorful canyonlands that were obviously inspirational for O'Keeffe, Ghost Ranch is now an education and retreat center run by the Presbyterian Church. Hiking trails – including the 4-mile round-trip trek into Box Canyon and the popular 3-mile round-trip to Chimney Rock – are open to the public, as is Piedra Lumbre Visitor Center , with displays about the area's natural history. The Ruth Hall Museum of Paleontology features exhibits on the trove of dinosaurs found right at Ghost Ranch. Horseback riding is offered for riders of all levels, and for kids as young as four. Fun factoid: scenes from City Slickers were filmed here.
