The John Dellenback Trail circles the sapphire blue Diamond Lake in south-central Oregon, only about 20 miles north of the state's more famous Crater Lake. The paved pathway connects the campgrounds that ring the shoreline and provides magnificent views of snow-covered Mt. Thielsen and Mt. Bailey. The lake's South Shore Picnic Area offers a nice resting spot to take in the views and enjoy a packed lunch.
For more outdoor adventure, the lake—nestled within Umpqua National Forest—is popular for fishing and boating; hiking and equestrian trails also crisscross the area. In winter, the waterfront trail can be used for cross-country skiing, snowshoeing, and mushing.
Parking lots can be found all around Diamond Lake; clockwise from the north end of the lake, you'll find them at: Diamond Lake Campground (east side of the lake), South Shore Picnic Area, Broken Arrow Campground (south side of the lake), and Thielsen View Campground (west side of the lake).
