Sierrans gather for a group shot before the 2014 King William parade

Welcome to the Alamo Group of the Sierra Club

We invite you to join our 2,000 members as we explore, enjoy and protect San Antonio and its surrounding areas. Come to one our monthly general meetings featuring prominent speakers on a vast array of subjects. Enjoy one of our monthly Lion’s Field events which will entertain and edify you with films and speakers on a variety of issues. Come walk, hike, camp or backpack on one of our frequent outings. Get involved in advocacy on local, state or national conservation issues. Help introduce local youngsters to the wonders of the outdoors with the Sierra Club Youth Outdoors program.

The Sierra Club is all about citizen action on critical issues. Quick citizen input often spells the difference between victory and defeat for important measures at the local and state levels.
