Treasure Cove Oysters emerge from the serene waters of Case Inlet, nestled within Puget Sound. With a vision to cultivate premium oysters, the Riley family embarked on this journey in 1991, laying the foundation for a renowned oyster farm.
Treasure Cove Oysters are distinguished by their cultivation process. They undergo a tide-tumbling method before finishing on the beaches. This technique enhances their texture and imbues them with a moderate salinity and a small, manageable size. The waters of Puget Sound complement this semi-tumbled cultivation. The result is an oyster that offers a distinct taste experience, celebrated by enthusiasts and chefs.
How Did They Get Their Name?
The name “Treasure Cove Oysters” derrives from the location where these Pacific oysters spawn. Which is near Treasure Island in the Case Inlet of Puget Sound. The choice of name reflects these oysters’ unique and valuable nature, akin to discovering treasure. The Riley family, who planted their first oyster and clam beds in 1991, chose the name to signify the premium quality and distinct characteristics of the oysters grown in this location.
This naming highlights the geographical significance and the family’s vision and pride in their oyster cultivation efforts, emphasizing the exceptional experience that Treasure Cove Oysters offer.
About Emerald Acres Oyster Farm
Emerald Acres Oyster Farm, the birthplace of the Treasure Cove Oyster, offers incredible views of the South Sound. It is just about 90 minutes from Seattle. Puget Sound, specifically Case Inlet’s nutrient-rich waters, creates a perfect environment for Pacific oysters.

Kevin Riley’s journey into oyster farming represents a significant shift from his previous career in technology to a passion-driven venture in aquaculture. He built his business from the ground up, establishing connections with some of Seattle’s top chefs and prestigious seafood markets. The famous Pike Place Fish Market has even featured his Treasure Cove oysters. However, the pandemic posed a challenge to the business, dramatically dropping customers. In response, Kevin discovered Hipcamp, a platform similar to Airbnb but for camping and outdoor experiences, which helped sustain the farm through difficult times.
The farm utilizes tumbling and beach rolling methods to cultivate the Treasure Cove Oysters, resulting in a unique deep, cupped, smooth-shelled oyster. These oysters have soft, plump meat and salty-sweet flavor with a clean finish, making them a favorite among oyster enthusiasts.
Through Hipcamp, Kevin Riley has been able to share the beauty and bounty of Emerald Acres Oyster Farm with visitors, offering them a chance to enjoy oyster feasts by the campfire and learn about the oyster farming process directly from him.
