What we're about

We are a long-established hiking club with a Meetup page to announce our hikes. Please go to https://simitrailblazers.com to learn more about us.

This is a volunteer organization of outdoor enthusiasts committed to the care and protection of our natural environment for the enjoyment of all. It is affiliated with the Rancho Simi Recreation and Parks District and was formed in late 1992. Regularly scheduled activities include: 3 weekly evening conditioning hikes in Simi Valley; weekly Saturday morning hikes ranging from the Simi Hills and the Santa Susana Mountains to the Santa Monica Mountains, the San Gabriel Mountains, and the southern Los Padres National Forest; 4- to 7-day camping-and-hiking trips mostly in national parks in the western United States; occasional easy-to-moderate short backpacking trips; and trail maintenance in Simi Valley and Oak Park on the 3rd Saturday of each month.

Sage Ranch Loop [adjacent to the Santa Susana Field Lab] HIKE (Simi Valley)

DESCRIPTION OF HIKE: Easy-to-moderate 3.5-mile loop with 500’ of elevation gain/loss.
This 625-acre park is located in the Simi Hills just north of the Santa Susana Field Laboratory (SSFL) (aka Rocketdyne/Boeing) at an elevation of 2,000’. It is full of world-class sandstone rock formations and the trail provides great views of Simi Valley and the mountains to the north. NOTE: A relatively short section of the original loop trail was closed in mid-2017 for the cleanup of the former trap and skeet range in that area. To compensate, a new “detour” section of trail has been established; it bisects the ranch and provides views of the heretofore unseen center of Sage Ranch. Our hike will be counterclockwise.

PREPAREDNESS: Bring 2-3 liters/quarts of water (or other suitable liquid) and lunch/snack. Wear appropriate footwear (preferably hiking boots) and be prepared for bright sunlight (sunglasses), heat (layers of clothing), and/or precipitation (rain gear). Hiking pole(s) and a camera might come in handy.

NOTE: At the beginning of each outing you will be required to read and sign a liability release form (a sign-in sheet).
