Where River Adventures Meet Small Town Charm

Spring-Fed, Crystal-Clear Waters

A unique feature of the San Marcos River is that its water originates from Spring Lake(opens in a new tab), where over 200 natural springs gush from the Edwards Aquifer. This supplies the river with cool, clear water year-round. The river boasts a steady temperature of about 72 degrees fahrenheit, making it a refreshing retreat, especially in the summer. It is the ideal spot for activities such as tubing or kayaking the San Marcos River with friends and family.

Spring Lake and The Meadows Center

Spring Lake is a unique blend of natural habitat and historical significance. The Meadows Center for Water and the Environment(opens in a new tab) offers guided glass-bottom boat tours(opens in a new tab), allowing you a glimpse into the underwater world filled with fish, turtles, and aquatic plants. It is a unique experience that makes you feel like you’re drifting over a living aquarium. The center also features a boardwalk trail(opens in a new tab) through the wetlands that is perfect for bird watching. This is easily one of the most memorable San Marcos attractions for all ages.
