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 Marconi Conference Center is situated on wooded 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.

Most rooms have stunning views; all are smoke-free, with private baths and study desks. The lounge area provides games, books and film libraries, snacks and beverages for evening relaxation. Breakfast, lunch and dinner are served to conference groups.

Meeting Pavilions
Some meeting spaces have commanding Bay views, others are in a peaceful forest setting. State of the art audio/visual and internet capabilities are available, and meeting facilities can be configured for casual or auditorium-type seating. Break-out rooms are within each Meeting Pavilion.

Marconi Hotel
The main building of the Marconi Wireless Station on this site is known as the Marconi Hotel.  This was quite a remote site in 1914 when the Hotel housed station workers and Marconi guests. 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.
