This steep mountain trail leads to the highest point in Arizona. If you consider it merely as a means to that end, however, you'll miss much of the reason to come here. Along its 4.5 mile course, a thriving alpine forest streaked with huge rock slides and avalanche tracks hugs the mountain's slopes. Scenic Hart Prairie stretches out the base of the incline and the Grand Canyon is easily visible on the horizon.
As the elevation increases, trailside vegetation shows more and more evidence of the extreme harshness of this environment. Near tree line what's left of the forest consists entirely of bristlecone pines bent and twisted by wind and frost. This hardy tree manages to live one of the longest lives on earth in one of the planet's most inhospitable environments. Above tree line the only plants that can survive are small tundra shrubs and wildflowers that huddle for shelter among the rocks. Some are found nowhere else in the world. Overhead, above Arizona's highest ridge, white-throated swifts dive and flash like miniature fighter planes as they feed on nearly invisible insects borne on the wind.
Humphreys Trail is steep and long and extremely rocky in its higher reaches. Above treeline it exposes you completely to the whims of nature. Here it may snow during any month of the year. In late summer monsoon storms can set the high country snapping with lightning. Be prepared to turn around and head for lower ground if a thunderstorm is brewing!
Once you do reach the summit ridge you'll feel like you're standing on top of the world. Off in the distance, the Grand Canyon, the Painted Desert, the mesas that are home to the Hopi Indians the Verde Valley and Oak Creek Canyon form a 360deg. panorama. And after you've seen it you'll be able to say you've been as high as you can get in Arizona.
