Snow may close the upper reaches of this trail in winter; late June to mid-October is the best time to hike it. There is no potable drinking water along the trail. Carry a water filter or water from home. The trail may be faint in places (particularly up near Deadfall Summit) so be ready for a few navigation and trail-finding challenges.
One end of the Sisson-Callhan Trail is at 3,500 feet near Lake Siskiyou and the other at a junction with the PCT at 7,200 feet among the Deadfall Lakes. In between, the trail climbs to the 8,020 foot Deadfall Summit and past the side trail to Mount Eddy. The Sisson-Callahan NRT is all downhill from Deadfall Summit. It trail can be done in either direction but a start at the Parks Creek Trailhead (with a car shuttle from the lower trailhead) allows for a mostly downhill journey. Running from the Parks Creek Trailhead to the end-of-trail near Lake Siskiyou is a good effort for most runners.
