Blue Bay sits on the shore of Suttle Lake in Deschutes National Forest, roughly 14 miles northwest of Sisters. This moderately priced Forest Service campground offers tent, RV, and primitive sites with direct lake access for boating, fishing, and paddling. The Suttle Lake Loop Trail connects campers to the shoreline and surrounding forest, and the campground operates seasonally during peak summer months when the lake is warmest and most accessible.
Blue Bay Campground accommodates a range of camping styles, including primitive tent camping and RV setups, though no hookups are available. Group sites and specialized accommodations are not explicitly mentioned, and glamping options are not available.
Weather and SeasonsBest season: summer. Summer offers the fullest access to Suttle Lake and the campground — warm, sunny days and calm water make boating, swimming, paddling, and trout fishing the main draw. Expect daytime highs roughly 70–85°F and cool nights around 40–55°F, with steady afternoon breezes off the lake; this is when trails, boat launches, and most services are fully available. Summer is busiest in July and August (especially holiday weekends), so expect crowds then but unbeatable lake recreation and long daylight hours
Peak months: July, August, September, June
Avoid: October, November, December, January

Natural Features and ScenerySuttle Lake fills a glacial basin at 3,497 feet, surrounded by Douglas fir, ponderosa pine, and mountain hemlock. Ancient lava flows and cinder cones from the Cascade Range's volcanic past frame the horizon. The lake reflects the forested ridges, and osprey hunt over the water while deer visit the shoreline. The Suttle Lake Loop Trail circles the lake through mixed conifer forest growing in volcanic soil.
