\u00a0From canyons and caves to waterfalls and wildlife, Indiana's wilderness is simply breathtaking. Visit Indiana's next\u00a0#The20IN20 list\u00a0focuses on the natural wonders of the Hoosier State. "There's so many natural features in Indiana to explore," said Lt. Governor Suzanne Crouch. "These 20 attractions\u00a0are all great reasons for Hoosiers to see the charm Indiana has to offer." See two stunning waterfalls about a mile apart at\u00a0Lieber State Recreation Area.\u00a0Cataract Falls\u00a0is the largest waterfall by volume in the state. The Upper and Lower Falls have heights of around 45 and 30 feet, respectively. Two pre-glacial bedrock ridges buried beneath ancient lake sediments of the Illinoisan developed the falls, making them true natural wonders. See for yourself why\u00a0voters chose Cataract Falls as Indiana's best waterfall. Indiana's\u00a0diverse habitats are home to over 400 documented bird species, making it the perfect place for a birding adventure. The\u00a0Indiana Audubon Society\u00a0recently created the\u00a0Indiana Birding Trail, featuring 64 great bird watching locations throughout the state. From the one-of-a-kind migration of Sandhill Cranes to rare bird sightings along with the swamp habitats of Indiana Dunes National Park, the experiences won't disappoint.
