Venue Description:

Henninger Flats, a forested notch sitting conspicuously on the mountain slopes above Altadena, is one of the most popular destinations in the San Gabriels.

In 1917, Mount Wilson Toll Road was used to bring equipment up to Mount Wilson Observatory. Today visitors can use the same dirt road to enjoy 180 degree view of Los Angeles. On clear days the view extend to the Palos Verdes Peninsula, and all the way to Catalina Island. While the road continues for over 10 miles to Mount Wilson, we will only hike 3 miles to reach Henninger Flats, where there is a campground and a visitor center.
