Tri-County Partnership to Create a Cleaner Coast

MARIN, SONOMA AND MENDOCINO COUNTY PARTNER TO CREATE A CLEANER COAST Teaching Leave No Trace Practices to Growing Visitor Audiences in Coastal Communities. Learn more by reading the Tri-County Partnership Press Release (6/15/2022).

The Lodge at Marconi, an upscale coastal retreat, is situated on 62 sprawling acres of rolling hills overlooking scenic Tomales Bay in Marin County.

The California State Parks Foundation acquired the property in 1984 with Buck Trust funds, remodeled it as a conference center, and gave it to the California Department of Parks and Recreation. It is now operated as a non-profit facility. 

The conference center operation enables these grounds to be preserved and protected, while the historical buildings constructed by Marconi await restoration

It offered the conveniences of a library, dining hall, billiard room and state-of-the-art plumbing. Built of concrete and tile, the three-story building's front verandah was designed in the classic Italianate villa style.
