A great starting point for exploring the numerous surrounding trails. Ideally, the descent via the Ribbon also ends here. From here, we took an Uber to the Ribbon trailhead to pick up our car. A good solution, as there are no shuttles available in the area, to our knowledge.

Super technical and rocky—expect tough climbs and fun, tricky descents. Take it slow, pick good lines, and enjoy awesome canyon views. Bring plenty of water and be ready for a real challenge!

The Coke Ovens Overlook is a great vantage point for an impressive view of the beehive-shaped rock formations created by erosion. These formations, shaped over millions of years from the Wingate Sandstone, get their distinctive appearance due to the weathering process. It's a fantastic spot to take a break and capture some memorable photos.
