Great Springs Project is working to create a greenway of contiguous protected lands between Austin and San Antonio over the Edwards Aquifer recharge zone. This green corridor will be connected by a network of spring-to-spring trails, linking four of Texas' Great Springs; Barton Springs, San Marcos Springs, Comal Springs, and San Antonio Springs. Great Springs Project envisions unifying existing local efforts to address the most critical water, land, wildlife, and public health challenges facing the Central Texas region.
