The hike starts off from the very good sized 40th Street trailhead that includes decent restrooms. You start off heading due south down a path that is inline with 40th Street that comes out of the east side of the trailhead. The trail starts off as a what was once likely a jeep road or two track.
On your right is wide open and relatively flat land that extends over to the Squaw Peak conglomerate. At 0.35 miles in you cross paths with Trail 100 where it squeezes through the mountains to Tatum.
The hike continues easy going to 0.5 miles where you finally start up a slight grade. It's barely noticed though and won't have much effect on you. At 0.85 miles in things change. Here is where the 'TWOBIT PEAK' sign-post is and you're eased into a grade more reminiscent of Squaw for the final 0.4 mile push to the top. This peak has it's own characteristic in that it's progressively steeper as you go.
The peak itself is immediately up to your left when you reach the saddle/ridge. The sub peak or the second bit of Two-Bit is off to the right. The views are as good as Squaw or Camelback as far as city viewing goes.
None known as this is part of the Phoenix Mountain Preserves
October to April is best to avoid the heat, but anytime if you're prepared.
None close as it's in the middle of the 6th biggest city in America.
