2025-09-23 18:00 - 21:30 (America/Denver) | Chumash Park, Flanagan Drive 3200, Simi Valley, CA, 93063, United States
4 miles, 950′ gain, Intermediate
Easy Option: 1.6 miles, 400′ gain, Fit Beginner
Hardest option: 5 miles, 1200′ gain, Intermediate
The entire hike outbound is a steady incline. Nothing super steep, just continuous and quite strenuous for many. There are virtually no junctions where one can get lost.
This is one of the more famous hikes in Simi Valley, and for good reason. Much of the hike takes place along the edge of the mountain. The trail in spots is a bit rugged and rocky, so a good tread on your shoes is recommended.
It is a part of the Chumash Natural Park that includes sandstone rock formations, caves, and beautiful vistas of Simi Valley. The land is owned by the Santa Monica Mountains Conservancy and the Rancho Simi Recreation & Park District. It is maintained by the Rancho Simi Trailblazers and patrolled by the Volunteer Trail Safety Service.
We’ll all begin the climb together. Those doing the easier option will stop after 0.8 miles and wait for about 45 minutes until the rest of us return to this spot for our social event. While waiting, they can continue to climb any portion they want and return to this spot, or just take in the views.
The rest will continue for 1.3 miles until a flat rock. Those that want the hardest option, continue for another 0.5 miles and 250′ gain to the end of the trail. Head back down the same way to the social event spot.
At the social event spot, we’ll be rewarded with sweeping views of Simi Valley and will share snacks and beverages.
There is really no way to get lost on this hike, so everybody will move along at whatever pace they want.

Interesting Notes
Here are a couple plants you are sure to see on this hike:
California Encelia
Aka, California Bush Sunflower, California Brittlebush, Coast Sunflower, El Dorado.
Center is brown. When the center is yellow, it is Brittlebush, from the brittleness of the stems. This is from the daisy family, and it is typically used as an ornamental plant.
Mediterranean Mustard / Black Mustard
Mediterranean mustard seeds are yellow or white, while Black mustard seeds are brown or black. The flowers look the same.
Flowers, leaves (mustard greens), and roots are edible. Can be used as a spice. Grind seeds and mix with water and vinegar to make prepared mustard. This is often a very abundant noxious weed (has been designated by an agricultural authority as one that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock.). It grows everywhere along the sides of the trail, often having to be cut back during trail maintenance.
Did you know that cabbage, mustard greens, collard greens, kale, broccoli, cauliflower, brussels sprouts, and prepared mustard, are all from different parts of the wild mustard plant?
