Winding through the heart of Oregon’s Cascade Range, the McKenzie Pass-Santiam Pass Scenic Byway offers 82 miles of breathtaking volcanic landscapes and pristine alpine wilderness. This National Scenic Byway loops from the McKenzie River ranger station through Sisters, treating travelers to some of the Pacific Northwest’s most dramatic scenery.

The route traverses ancient lava fields at Dee Wright Observatory, where a stone structure provides 360-degree views of snow-capped peaks including Mount Washington, Three Fingered Jack, and the Three Sisters. Dense old-growth forests of Douglas fir and western red cedar give way to crystalline Proxy Falls and the turquoise waters of Clear Lake, fed by underground springs.

Stop at Sahalie and Koosah Falls to witness the McKenzie River plunging through basalt canyons. The charming mountain town of Sisters offers artisan shops, galleries, and farm-to-table dining—perfect for a midday break.

Best Time to Visit: Late June through October, as McKenzie Pass (OR 242) closes during winter months due to snow.

Duration: Allow 3-4 hours for the drive alone, or a full day to explore waterfalls, hiking trails, and viewpoints along the way.

This byway rewards those who take their time with unforgettable volcanic vistas and cascading waterfalls at every turn.
