Take the famous glass-bottom boat ride, one of the most popular ways to view the bubbling springs and the Natural Aquarium of Texas. This ride introduces visitors to an excavation site from which artifacts dating as far back as 12,000 years have been recovered. The Endangered Species Exhibit gives visitors an up close look at the unique species that live only in the San Marcos River. The new "Wetlands Walkway" exhibit offers a great place for bird watching, located just outside the park along the banks of the San Marcos River. With the entertainment venue of the park focusing on nature, Aquarena is becoming a new highlight for nature tourism. Open year-round. No admission fee to the center, but there is an admission fee for the boat ride.
