Red Mountain is about 30 minutes from Flagstaff. The ride there is scenic and in the shadow of Humphrey's Peak. The trail in is of moderate grade but can easily be done comfortably in a couple hours. The trail up contains a variety of desert plants and vegetation, plus ponderosa pines, junipers and pinyons. At the base of the mountain is a lava cone, which you can climb up and into. You can also explore trails and crevasses at the foot of the mountain. Bring your camera, because there is a lot to photograph.
