From the treeline, pick the steep switchback that goes up and to the right into the trees in between Marshall Road to the A-Frame and Rumbling Paddoka. This is my favorite warm up trail. The trail rises steep, levels out then rises quickly again between the trees to the A-Frame or East Tower for a great view of the whole Lagoon from the east and beautiful Vaca Valley.
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!
