Discover the Great Outdoors... In Your Own Backyard

We are the Orange County Sierrans Section of the National Sierra Club Angeles Chapter. We are open to all and welcome people of all backgrounds and ages.  Our schedule of activities includes hiking, backpacking, hikes for Conservation, special Newcomer events, BBQ’s, City Walks, destination multi day trips to lodges, backpacking, camping, winter sports and ski trips.  
We are a little more than a local organization. We are backed by the 40,000 member Angeles Chapter and the 650,000 member National Sierra Club.
The Angeles Chapter boundaries are from Santa Clarita to San Clemente, from the ocean to the foothills.
The Angeles Chapter has the largest outings program in the US.  We have a long tradition of outdoor activities, so come join us.
