Though this trail section is short, don't be fooled into thinking that it won't be a workout. The ascent from near the Unnamed Zig-Zag Trail to the A-Frame is incredibly strenuous. The first .25 of the trail is mellow, and you should enjoy use this portion as a warm up. Once you pass the .3 mile mark, the grade increases steeply, and it won't stop until you reach the top. <br><br>The path is a combination of dirt road and paved path, so the steep grade will be the only thing that you'll need to focus on.
Last little climb to the top of the first tower or A-Frame. You can see the Marshall Road Service road to the left.
After the first steep climb the trail crosses this confluence of trails before you head up the next steep section.

1st Tower with a view of Vaca Valley facing I-80. Amazing view in the winter, when everything is green!
