The Butterfly Garden was designed and installed in 2000 by the Friends of Kerrville-Schreiner State Park. The garden is approximately 104' X 104' and is enclosed by a deer proof fence. In the middle of the garden is a fire ring with seating with a raised circular bed separating this area from the remainder of the garden. There are several mulched paths marked by flags for the milkweed which are used for data collection. In 2006, the garden was certified as a Monarch Way Station.
