I LOVE this place! The Brenton Arboretum is in Dallas Center, Iowa and just a short drive NW of the metro. It’s free to get in and has an amazing natural playspace in addition to lots of trails, a lake, and a new stone labyrinth. It’s a perfect place for sunny Fall days, and we had a lovely hike and play this past week. They also have lots of events, so check their site or my local events listing page to check them out.
