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.
Tree covered, may have poison oak as well.
