Bocce Court with Har-Tru as surface
The best surface for a bocce court is the most expensive. The Har-Tru surface is a very fine granular product that compacts well and is very smooth for rolling bocce balls.
Oyster Flour Bocce Court
Many California built bocce courts are topped with oyster flour or shell. This is a white organic material that provides a good top coat and playing surface. It is white when first installed and later turns gray.
