Upper terminus of Mount Lowe "Motorway" trail, a gravel double track that starts at about 600 m elevation from Chaney Trail in Altadena and ends here at Mount Wilson Red Box Road at about 1550 m above sea level.

Short tunnel on the eastern slope below San Gabriel Peak, part of the old Mt Lowe Motorway, that was never paved. The tunnel is very short, so you don't have to worry about bringing light. The road continues to the trailhead half a mile uphill.

If you come down from Pincrest Dr, cross the bridge and keep right walking a loop to get under the bridge. From here follow the creek by crossing the stream over rocks and trunks around 10 times before you reach the small lake with the waterfall. Have great fun by taking a "shower".

40 foot water fall in the San Gabriel Mountains. The hike up to the falls is moderate with several stream crossings. It can get busy during peak times, but is definitely work the trek up.

Millard Falls is a small waterfall in the mountains. It is in a peacefull setting that is normally on too busy. There are some bolts in the rock wall near the falls, so there is the possibility to rock climb.
