The best wildflower viewing times depend on seasonal rains and temperatures but on average one can find abundant flowers in the 5,000 to 7,000 foot elevation of Canyons of the Ancients National Monument (and similar areas of the Four Corners) from early April to the end of June; in the 7,000 to 8,300 foot elevations of Mesa Verde National Park from mid-May to the end of July; in the 8,000 to 11,500 foot elevations of the mountains of the Four Corners area from June through September; and in the 11,500 foot and higher alpine areas from mid-June to early September.
Driving the San Juan Skyway and through Mesa Verde, Canyonlands, and Arches National Parks will give you a glimpse of the stunning variety of flowers and trees of the area, but getting out for a hike will amaze you.
