This is a challenging, steep, and exciting route that goes to the summit of the Volcán de Agua. The route begins and ends in the town of San Juan del Obisbo, about 5 km from the center of Antigua. The route follows dirt road and well used foot trails for a 17 mile round trip with 7,678 ft of elevation gain (27 km/ 2340 m gain).
 

Whiteface is a mighty mountain, (5th highest in NY, at 4638 ft.), and perhaps the most unique of the 46 high peaks in New York, because it is so accessible. It offers many ways to summit it’s crowded and overpopulated peak. There are two different routes to hike up, or you can simply drive your car up the Whiteface Memorial Highway, which snakes its’ way up the Northeastern slope. It is almost all by itself, a lonely peak separated by the rest of the 46 peaks, with a world-famous ski resort on its’ eastern side.

24 miles in total. You run out to Grey Owl’s cabin and then turn around and run back to the start. The trail is full of rocks and roots and lots of ups and downs, which make for some tricky technical running most of the way.
