Chandler unveiled another dynamic, mixed-use facility in April 2008 with the Veterans Oasis Park and Chandler Nature Center located in the southeast corner of the city at the intersection of Lindsay and Chandler Heights Roads. The center includes four classrooms for wildlife preservation and environmental awareness, exhibit areas, an outdoor amphitheater, a nature store, and an urban fishing lake, all surrounded by more than four miles of trails. A primary purpose of the facility is to recharge reclaimed water into the ground for later use. The staff works with local schools to develop nature-oriented activities that complement their curriculum. Programs offered for residents and visitors cover topics such as birdwatching, green living, gardening, water conservation, nature photography, orienteering, alternative energy, and stargazing. Entrance to the Chandler Nature Center is free and visitors are welcome to view the exhibits and walk the trails around the urban fishing lake.
