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".

Mount Lukens is the highest mountain within the vicinity of Los Angeles. It has become a popular destination for experienced and less experienced outdoors enthusiasts thanks to its accessibility. If you would like to get there via a less crowded route, I would suggest to follow Haines Canyon Road.

You can reach the upper falls by following the path with the sign that says "Not a trail". It does end as a trail, but at the upper portion of the falls. There's a nice pool of water there and a rope that someone installed to easily access it.
