Blue Diamond Marina and Resort

Blue Diamond Marina & Resort is Priest Lake’s deepest water marina, located on the secluded west shore of Cavanaugh Bay just 5 miles north of Coolin, Idaho. We offer all-season deep-water moorage in covered and uncovered slips with access for the physically challenged, inside secured storage, a wide variety of modern boat rentals, lakeside lodging and The Waterfront Restaurant specializing in family style Italian cuisine.

Enjoy the pristine beauty of Idaho’s Crown Jewel this winter! Priest Lake is home to an extensive system of cross-country ski and snowshoe trails and over 400 miles of groomed trails for snowmobiling. Stay with us in our cozy lakeside lodging and you’ll be a stone’s throw away from the Rocky Point Trailhead. For those of you who find us on your snowmobile adventure, pop in for a cup of hot chocolate at The Waterfront – on winter weekends the restaurant is open as a warming hut.


I wanted to let you know that Bev and I came to your restaurant last Saturday night for dinner and had one of the best dining experiences we have had in some time. Your Chef Melissa was a delight and really gave us a most warm reception along with your waitress. They provided us with exquisite service and attention and the quality of the food offerings were much beyond our expectations. 
There is no doubt we will return and we also are informing our various lake friends that they need to give your restaurant a try as it goes way beyond what has been offered in recent years.

“Bad luck — good luck: Cavanaugh’s was closed for a wedding rehearsal dinner, so our group drove over to Blue Diamond for a first-time meal. The Italian dishes I had were fantastic, the service excellent, plus our chef, Melissa Lewis, ducked out of her kitchen for chat about what led her to decide to spend her summer cooking fine cuisine in northern Idaho.”
