One of Boerne's most delightful attractions is the Cibolo Nature Center. Tucked amidst huge sycamore trees along the Cibolo River, the CNC boasts marshes, a butterfly habitat, wildlife and several hiking trails. In June 1997, the center lost many trees to a large summer storm. 15 inches of rain fell on the community. The resulting flood exposed dinosaur footprints on the Boerne Lake spillway. A careful replica of the tracks was made and positioned next to the gazebo at the nature center before the tracks were buried by water or vegetation again. This is a favorite exhibit amongst children. These days the center is host to school field trips, bird watchers, and nature lovers in general. The center hosts seminars on wildlife, bats, and even astronomy.
