Battelle-Darby Creek Metro Park is one of the largest parks in the Columbus area with over 6,600 acres. Founding members of the OES began visiting the park long before the OES was formed. Battelle-Darby Metro has numerous hiking trails, spots for fishing, athletic fields, playgrounds, a few Indian mounds, remnants of pioneers, and several cemeteries located off-trail. The Big and Little Darby Creeks are home to more than 86 species of fish, five of which are on Ohio's endangered species list, and 41 species of freshwater muscle. There are more than ten miles of trail winding through this enormous and beautiful park for all to enjoy. Make sure to check it out if you're ever in the area!
