This is the most popular and crowded route to the summit in the summer. The first 2.1 miles of the trail are a hike through forests. When you cross Loowit Trail there is a toilet on the right. After this the trail follows the rocky ridge and is marked by large wooden posts almost to the summit. You'll pass a couple tripod monitors on the ridge that give it its name. After the last post, just follow the ridge to the summit. In the summer, it's a dusty crowded hike. In the winter, you'll want crampons and an ice axe or be sure-handed with some trekking poles.
Total distance is 4.5-5 miles one way with 4600 feet of elevation gain.
