The Boathouse


We would love to host your next event

Our family has been in the restaurant space since 1990. A sincere passion for connecting with people through food and service has been our hallmark through multiple establishments in the Central Valley. We are humbled to continue Susan’s vision of what River Islands is to become and excited to call The Boathouse our newest home. We are proud of the local relationships we have developed over the years with our food partners to provide you with amazing offerings from this region.

That is why we start with locally sourced, fresh ingredients to use in our scratch-recipe kitchen, from our Stock Yards Beef, Wagyu Burgers, fresh seafood, farm-fresh locally grown produce, artisan bread from Max’s Artisan Bakery, all delivered by US Foods, and others throughout the greater San Joaquin Valley. Our house wines are from local McManis Family Vineyards.

Add our lakeside setting with its picturesque views of the Mossdale Bridge, pic-inspiring sunsets, activities like bocce ball, volleyball, cornhole, seasonal boat rentals, 6-acre park, top that off with a hospitality-forward staff and you have The Boathouse at River Islands. Our family strives to provide you with the environment to create memories, life is about stories and we are honored to be part of yours.
