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.

Blue Diamond was originally built in the early 1900s as the logging truck repair center for Diamond International Corporation and continued in that capacity for several decades until it was converted to a marina in the 1960s. By the late 1980s the aging buildings were suffering from their years of history. Restoration and renovations began in the mid 1990s, and today, Blue Diamond stands as a modern marina while still retaining the ambiance, charm and relative solitude reflective of the facility's history.
