Holliday Park is one of Indianapolis' oldest existing parks, and is a great place to visit all year long. The Nature Center, located in the middle of the park, is an ideal indoor destination for all ages to learn and explore. Habitat Hall at Holliday Park Nature Center The 13,000 square foot Habitat Hall at Holliday Park Nature Center focuses on the history of Marion County and Holliday Park. Visitors of all ages can learn about natural and environmental history with hands-on, discovery-based activities. The White River Water Table offers a real water exhibit that kids can touch. The Music of the Wetlands exhibit is an auditory experience where kids can learn about the calls and noises that local animals make. There are spaces to play and observe, as well as games and puzzles for little ones. The Nature Center also has a big exhibit that looks like an indoor treehouse. This elevated hardwood forest viewing area allows visitors to experience the forest canopy and see the wildlife that calls Holliday Park their home. From the viewing area, visitors can see the bird and wildlife observation area, which offers feeding stations and a sound system that allows guests to hear the birds. Two classrooms just off the Nature Center host classes on nature, after-school activities, and arts and crafts with an environmental theme. Holliday Park Outdoor Spaces The Nature Center is just one part of Holliday Park. The entire park sits on 94 acres, and includes a playground featuring a rock-climbing wall, large slide towers and bridges. The renovated Ruins on the property reopened in 2016 with a children\u2019s water table, fountains and new seating areas for concerts, festivals and weddings. The Holliday Park Pavilion provides large groups a shaded, open-air seating space. Located near the playground and including three single-stall restrooms, families now have a space to relax all day. The pavilion is available for rental for larger gatherings. If not reserved, the space is open for all visitors throughout their time at the park. Nature lovers can fish in the west fork of the White River at Holliday Park, and 3.5 miles of trails help visitors spot deer, fox, beavers, rabbits and other wildlife in the area.
