The Center for Alaskan Coastal Studies (CACS) is a 501-c-3 environmental education not-for-profit organization in Homer, Alaska. Established in 1982, CACS delivers educational programs and guided tours to over 11,000 students and visitors every year. Our grassroots organization enjoys the support of over 350 members, 100 volunteers and a variety of businesses in Homer that assist us in fulfilling our mission.
Since 1984, CACS has held the annual Kachemak Bay Coast Walk event that involves more than 200 volunteers who adopt a section of the Kachemak Bay shoreline and walk it annually, surveying changes, collecting data on marine life and human impacts, and cleaning up beach litter and marine debris.
