Hidden Valley Natural Tunnel

The hike here was nice, I had the trail to myself, there were bikes going up and down but it was nice to hike solo. I really enjoyed being here by myself.it was so quiet and serene. This was my first time hiking to the tunnel it took me an hour and ten minutes to get to the fork...I highly recommend you hike this trail and go visit the hidden valley natural tunnel to see how beautiful it really is in person it's one of those "you had to be there" things...it's a good place to escape the sounds of the city to find the quietness of nature. The tunnel is also large enough to walk through without slouching over at all...I am 5'9 and can walk through without touching the top or sides...I hope y'all enjoy my little review and maybe I'll see y'all out there somewhere...have a blessed day...hike safely...

actually there is no path way after hidden valley, so you guys have to climb to continue the trail to fatman's pass

First time on this trail, stats off a little rocky and steep, but gradually gets less rocky and more sandy. The whole loop took me about 2 hrs, i did stop and take several photographs along the way, you have to. The views from up there were amazing. The tunnel itself pretty cool that it naturally formed that way. My only gripe is the trail isn't marked in a few spots and i got off trail a few times but managed to find my way back.

This is beautiful terrain to hike with very big rocks around. We hiked from the east side of Sount Mountain, so we followed the desert side trail, secret trail, young man's trail. This was moderate to extreme hike. Also this trail is not found on city map or all trails. We followed Google maps to hike through. The best way to access this spot is to use the Fat man's pass through Mormon trail or the north side of the south mountain. Beware Google maps directs you to the east side when you search for Fat man's pass.

What a treasure in the middle of South Mountain! We took the Pima Wash trail to the outposts then hooked up to the Maricopa national trail to the Hidden Valley trail. This was apr 6.5 miles out and back. Not a beginners hike with rocks and some big steps. WATCH for fast bikers! Once on the national trail expect elevation climb and cool pancake stacked rocks. Totally fascinating! Clean bath stalls, shade and picnic area at this trailhead.
