Explore and learn about our Texas ecosystem at the 40-acre Elm Fork Nature Preserve (EFNP), located within McInnish Park. Discover how animals, water, and even humans impact our ecosystem. The day will begin with a guided hike and trail cleanup and end at our Nature Center where kids and families can enjoy crafts, snacks, and entertainment. The Elm Fork Preserve Trail is a loop, eight-tenths of a mile long, good for all skill levels. Be sure to dress for the occasion and come help us keep our Carrollton Parks beautiful! Closed-toed shoes and long pants are required. Children under the age of 16 must be accompanied by an adult. For more information call 972-466-3080 or visit the website.
