Telegraph Canyon Trail

Highlight (Segment) • Trail

Telegraph Canyon Trail is one of the most popular paths in the entire park. It leaves the visitor's center as a wide, smooth road and eventually narrows a bit, but it's pretty smooth the entire way. As you approach Four Corners, the trail starts to become more hilly, but it's always considered a "green" trail in terms of difficulty.
