Join the First Day Hike Challenge in Iowa State Parks DES MOINES – The Iowa DNR and Travel Iowa invite Iowans to participate in the 2021 First Day Hike Challenge to ring in the New Year through the digital State Park Passport. The challenge takes the place of traditional guided hikes due to COVID-19. “We are looking for ways to encourage both outdoor fun and social distancing,” said Todd Coffelt, Bureau Chief of Parks, Forests and Preserves. “First Day Hikes are a popular tradition in state parks, and the passport is a great way for people to enjoy winter hikes on their own or with their families.”
