Follow the directions in the "Getting There" section of the main page. This trail branches off from the lookout trail at the South Lookout.
This route descends 600 feet to the valley below and gets you some up close and personal looks at the River of Rocks. These massive boulder fields were deposited here during the last Ice Age, approximately 10,000-15,000 years ago. The rock is quartzite mixed in with some glacial cobbles. If you venture out onto these rocks, make sure you are very careful because they're quite shifty. The trail makes a loop back up around to the south ridge of Hawk Mountain. This means you'll gain all 600 feet again, but be rewarded with some nice views once on top. The loop trip is about three miles altogether.
Comfortable hiking shoes, water/snacks, trekking poles, and a camera.
