From Sunriver follow the directions to the Cascades Scenic Byway, and Mount Bachelor. The lake areas are clearly marked when the turnoffs are near.
Sparks Lake is part of the Cascade Scenic Byways area, consisting of several lakes, and not far from Mount Bachelor. Sunrise is the best time for creating images. Even though there was no clouds and colorful skies I was happy with the fog and mist rising off the lake. There was a hint of red in the sky, which added to the mood.
