There’s no better place than Red Butte Garden to celebrate Arbor Day! As Utah’s very own arboretum, we can't wait to share the wonderful world of trees. Due to the generous support of Rocky Mountain Power, join us for a fun day of activities and leave with a free tree to take home (while supplies last). Thanks to funding in part by Salt Lake County Zoo, Arts, and Parks Program (ZAP) Arbor Day is a ZAP Free Day! Everyone enjoys free Garden admission.
