You can find Hobo Cave, a small cave beneath a rock buttress, and Crown Rock, a large outcropping of red rocks suitable for scrambling.

Flagstaff Mountain is home to a variety of wildlife. Hikers and cyclists often report sightings of deer, various bird species, and occasionally even larger mammals.
