Arthur's Rock lies just off the main Arthur's Rock Trail down a short spur trail. After cresting a steep gully, you arrive at the summit of the very popular Arthur's Rock. From this large rocky summit, you get fantastic views of Horsetooth Reservoir and the surrounding area. This is a great place to find a comfortable seat and take in the views before heading back down the gully to the main trail.

This short, but steep section of switchbacks between the junction of the Westridge and Timber Trail and the junction of the West Gulch and Timber Trail packs a punch! Fortunately you are protected from the sun by tall pine trees that line the trail and get great views of the main Lory State Park area and of Horsetooth Reservoir through the trees.
