A nice hike (requires a shuttle) would be from the canyon east of the Sunset Point rest area and take out at Badger Springs.
Trailhead begins at the east side of I-17 right at the Sunset Point rest area.
From the canyon follow east on cow trails in the canyon bottom about 2 miles or so. Then as you meet the Agua Fria (very obvious) head northish for about 5 milesin the Agua Fria Cyn. . After these 5 miles, there will be a cairn in the river on top of a large rock telling you that you are at Badger Springs. Exit the Agua Fria to the left (NW) up this side drainage about a mile to where your shuttle vehicle will be if you exited I-17 @ Badger Springs and then followed the dirt road(s)Southeast to where a large boulder blocks the road.
If you are a fast hiker, it's about a 4 hour trip. Slower hikers will take up to 6.
In spring, when there is a lot of runoff, the Agua Fria runs pretty big, hampering quick progress up stream & at crossings.
If you are coming from Phoenix, check for water in the drainage where it runs under I-17. If there is running water there, there will be a lot of water throughout this hike.
The scenery once you are in the Agua Fria if Fantastic !
