Splash into Science is an immersive snorkeling program which provides low-impact educational fun in the spring-fed, crystal clear waters of Spring Lake, the headwaters of the San Marcos River. Spring Lake is home to spring-fed waters that remain a constant 72 degrees year-round, seven endangered and threatened species, and one of the longest continually inhabited sites in North America. This program aims to connect guests to the wonders of our local ecosystem and our relationship with the environment.
