I go hiking at Estrella Mountain which is in West Phenix. There's a hike that's about 3.4 miles and it takes us about 3 hours with moderate terrain. I'm kind of a baby so I thought it was rough terrain. Hence, the reason why it took us so long to get through it.
I know there are closer ones in Scottsdale. You can probably look up "Scottsdale hiking trails" on Google and get some good results. Have fun!
