Peter Greenberg’s The Travel Detective: Hidden Gems

Apr 14

Hidden Gems of Napa Valley

“It may be best known as one of the great wine making capitals of the world. But I’m taking you way beyond the vineyards. Check out my hidden gems of Napa Valley, California.”

Peter Greenberg

We’re excited to share that the Bale Grist Mill State Historic Park has been featured in Hidden Gems of Napa Valley—a travel series that shines a spotlight on the lesser-known experiences that make each destination truly special.

Hosted by travel expert Peter Greenberg, Hidden Gems explores cultural treasures, local traditions, and unique adventures that often go unnoticed in mainstream travel guides. The series celebrates authentic experiences—from regional cooking classes with local chefs to outdoor excursions and meaningful cultural sites—and we’re honored that Bale Grist Mill is recognized as one of them.

This historic water-powered mill is a rare and beautiful reminder of early California agricultural industry and community, and it continues to bring history to life through weekend milling demonstrations and educational programs. It’s one of those places that locals cherish and visitors are delighted to discover—especially those looking to connect more deeply with the history of Napa Valley.

This segment segment will appear on PeterGreenberg.com, within the PBS television series The Travel Detective, and digitally on Amazon Prime and AppleTV+.

We hope you’ll tune in—and come visit in person to experience this special piece of Napa Valley history for yourself!
