Join Ranger Al Blank on a walk up the Marincello Trail. Learn about the infamous Marincello Development was that was planned for this area. See remnants of this once popular idea. We will leave from Tennessee Valley and walk up to the Miwok Trail. Bring your camera, good hiking shoes, and dress in layers. The walk is moderate to strenuous but the views are spectacular. Heavy rain will cancel. Bring water and even lunch if you’d like.
