Brown Mountain Dam

Updated: Apr 12, 2019

Hike near the NASA Jet Propulsion Lab that offers diverse scenery, over a dozen bridges/water crossings, and a 80+ foot waterfall spilling over a dam.

The Brown Mountain Dam is one of the lesser known "Waterfalls" of Southern California, likely due to the man-made structure. The 8+ mile trek will take you to a dam that is over 80 feet high and has water falling from it at most times.


The dam was constructed in the early 1940s by the US Forestry Service.


The hike itself is roughly 8.4 miles out and back with only about 600 feet of incline. It is not particularly demanding and there are several great spots with benches and tables to take a break. A lot of the trail is covered by trees, so the sun doesn't beat down as aggressively as it does on most SoCal hikes.


This proved to be one of my favorite Southern California hikes due to the variety of the trail. First, you see the ponds of the Jet Propusion Lab, followed by several bridge crossings with each bridge seemingly a unique design. There are a few water crossings and quite the variety of vegetation along the trail. You'll pass a campground, picnic area, and the ruins of several structures on your way to the dam.




Know Before You Go

  • While the trail is mostly shaded, ensure that you have plenty of water and sunblock.

  • Once the sun goes down, the temperature drops precipitously - be sure to wear layers.

  • After substantial rain, the water flow will increase - use caution when crossing water. Prepare to get your feet wet.

  • Some of the rocks and logs are a bit unstable at the water crossings, sneakers with good traction are recommended.

  • Know the look of poison oak and avoid it at all costs.

Location


Easily accessible moments off of the 210 Freeway, close to the Rose Bowl. The parking lot is limited to about 15 vehicles, so if that is full you will have to park in the residential neighborhood. Recommended to arrive early so that you can secure a spot.


Video


The video below was taken on an iPhone while hiking, so apologize for any shakiness. The video features several of the bridges as well as the dam at the end of the hike.
