Monarch butterflies are headed south for the winter, and the National Park Service and the city of St. Louis are celebrating the journey with the Great MonArch Migration event. Pollinator experts from the Missouri Botanical Garden, Saint Louis Zoo, and the Missouri Department of Conservation will lead monarch-themed activities, like making milkweed seed balls and insect hotels, and will share monarch gardening tips.
Activities will take place in front of the new west entrance to the Gateway Arch as well as inside the Arch Visitors Center. Free refreshments, native plants and seed packets will be available while supplies last.
It's also the National Park Service Fee Free Day, in which the entrance fee to all NPS sites is waived. Visitors to the Gateway Arch can enjoy $3 off their adult tram ride ticket or documentary movie that day.
Saturday, September 29 from 10 a.m. to 1 p.m. at the Gateway Arch.
