Welcome! We are the Orange County Sierra Singles Section of the National Sierra Club Angeles Chapter. Our schedule includes Hiking, events for Little Hikers, Backpacking, Weekly Conditioning Hikes in 5 Orange County locations, hikes for Conservation, special Newcomer events, BBQ’s, events for 20s30s, winter sports activities, ski trips, bus trips and Adventure Travel. We are open to all ages and marital status. Our events are led by qualified leaders who have been through extensive Leadership Training before they receive their leadership rating. The mission of Meetup is to help people self organize into local groups. Orange County Sierra Singles may sponsor local events as well as international and out of state events, so we are a little more than a local organization. We are backed by the 45,000 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 is the largest in the US. The Sierra Club is the oldest and largest environmental grassroots organization in the nation. The Sierra Club was founded in 1892 by the famous naturalist, John Muir. Not only was this guy America’s best known voice from the wilderness and a most effective conservation leader but he was a fearless mountaineer taking enormous risks climbing in the High Sierra, solo travel on crevassed glaciers and exploring Alaska in a little canoe. Look for John Muir on your California quarter. What other organization can beat that? We have a long tradition of outdoor activities, so come join us. You might even want to become a member of the Sierra Club and know you are helping to save our remaining wild places. “Explore, Enjoy and Protect.”
