Harquahala Mountain Summit Road Scenic Drive

For hikers, a pack trail leads from the summit down the mountain through the Harquahala Wilderness Area. The trail has several difficult and steep portions. For the history buff, the drive displays old mining debris, shafts and stone houses from earlier miners.

For the nature lover it has beautiful Sonoran Desert scenery with blooming flora March through May and distinct ecosystem variations can be seen with changes in elevation. In addition to the typical desert reptiles and critters which can be encountered, bighorn sheep may also be spotted.

The grand finale is realized at the summit with the Harquahala Peak Observatory. The observatory was built by the Smithsonian in 1920 to measure and record solar activity. It was abandoned in 1925 and in 1975 was listed on the National Register of Historic Places and has since been stabilized.
