Salt-Polished Secrets of Casco Bay: A Private Oyster Farm Tour and Tasting
Shucking demo included! BYO Cocktails • 1.5 Hours • 2 to 12 people • Age 18+ to book
The skiff noses out from Yarmouth’s town landing and the river lets go, easing you into Casco Bay’s steady pulse. Gulls heckle from the channel markers, the tide tugs at the hull, and the wind—always with a mind of its own here—ruffles the surface like corduroy. A stack of steel oyster cages clinks at the bow. Somewhere below, thousands of bivalves are busy at work, filtering the bay clean one breath at a time.
Trail Wisdom
Dress for spray and wind
Layers and a windproof shell keep you comfortable; it’s often cooler on the bay than onshore.
Non-slip footwear
Boat decks can be wet when cages come aboard—closed-toe shoes with grip help you move safely.
Pack a small cooler
Bring a personal cooler with ice if you plan to purchase oysters after the tour.
Time your meals
No bathroom onboard; use facilities before departure and plan meals around the 90–110 minute ride.

Conservation Note
Oysters improve water quality by filtering the bay—pack out all trash, avoid disturbing eelgrass beds, and choose reusable containers for snacks and drinks.
Yarmouth’s Royal River once powered shipyards and mills that fed a thriving working waterfront; aquaculture is the modern continuation of that maritime craft.
