You and your scouts will discover the unique ecosystem created by the San Marcos Springs on your trip to Spring Lake in San Marcos, Texas. Scout program participants have unlimited access to the park grounds, the picnic area and all of the exhibits, and displays prior to and after all programs. Not all programs complete badge requirements. Badges or patches are NOT given out during the tour. Please wear field trip type clothing - loose comfortable clothes and sturdy outdoor rubber soled shoes. Every tour includes a glass-bottom boat ride.
