We Followed a Sand Road to One of the Wildest Slot Canyons in Utah To reach this canyon, we had to air down our tires and take on four miles of soft, deep sand. No signs. No service. Just a sliver of a road cutting through the desert. And at the end of it? One of the most stunning, narrow, glowing slot canyons we’ve ever stepped into. This is Peek-A-Boo Canyon (also known as Red Canyon) and it’s one of Southern Utah’s best-kept secrets. 📍 Near Kanab, Utah 🎒 4WD required — or a long walk in 🎬
