1600 feet gain
From Loma Alta Drive in Altadena, drive up the Chaney Trail (past a locked gate that opens at 6am) to the top of sunset ridge, where there's parking by the roadside. The trail starts east on the gated paved sunset Ridge fire road.
This is a fun hike with quite a bit of diversity. The hike starts out on Sunset Ridge, with great views of Millard Canyon and a 50 foot waterfall. The trail then drops sharply into a dark and heavily wooded canyon with an abandoned gold mine to add an interesting twist to the trek. The hike through the canyon has many lovely spots with gentle pools and small cascades. Bring along a camera. Note that the route show in the topo map was from the hike outlined in 101 Hikes in Southern California. Route finding was a little challenging, so hikers should make sure to have a map when hitting the trail.
