Hike to the Wind Cave in Usery Mountain park in Arizona.
This trail is well marked and just North of the East Valley. These two facts make it a very popular trail on weekends. Unless you get to the trailhead really early, you will likely have to walk a bit to get to the trailhead. No big deal, after all, that's why you are out here anyway.
There are two trails at this area. The Pass Mountain trail circles the mountain, while the Wind Cave trail hikes up it's face. Take the Wind Cave trail route.
Since there is a large number of people with all different abilities, remember your hiking etiquette. Yield to those people going uphill. Let faster hikers pass you.
Dogs are allowed but must remain on a leash. The hike is pleasant and not very difficult. After walking through the desert for a while, the trail starts upward with a series of switchbacks as you climb out of the parking area. The views of the parking area and the east valley make themselves visible as you climb higher.
Once you reach the wind cave, take a look around and enjoy the view. If you are still restless and have advanced hiking ability, perhaps you want to check out the mysterious route to the summit.
When you are finished snapping pictures and eating lunch, return the way you came.
Secret summit route from Wind Cave:
This un-maintained trail starts just to the right of the wind cave. There are some signs that mark this trail that state, "The trail ends here" and "Past this point is not maintained". If you go beyond those signs, you will notice the trail continues.
Leave the crowds behind as your hike quickly goes from populated to deserted. As the sign said, this trail is not maintained, so finding the route to the top can be tricky. Some nice hikers have tied red ribbon to the bushes overhanging the trail to help you find your way, but it can be difficult to spot them. There are also some hikers who have painted arrows on rocks to mark a trail. There are several routes to the top. If you loose the trail and have the skills, you can always go cross country and make your own route.
Expect to do a little scrambling, as this trail is steeper than the maintained trail to the Wind Cave. After another 15 minutes and 300 ft additional elevation gain, you will eventually make it to the top. You can see the Four Peaks, Superstition Mountains, and the east valley from up here. Plus, you don't have to share the views with anyone else.
When I was up here in January of 2002, there was a little Budda statue sharing the view with me. I think he was contemplating the hike down. Best to leave him to his meditation.
There were also a colony of bees that had made it's home in a crack in the rock. Give them some distance just to be safe (no pun intended).
