The Butterfly House & Aquarium is a 501(c)(3) nonprofit organization. We are the only public salt water aquarium in the Dakotas and one of only a few butterfly houses that are open year round. We opened our doors in December of 2002 as a Butterfly House. In 2011 we added aquariums and have doubled our annual attendance and continue to grow every year!
Your admissions and donations help support our mission of Inspiring conservation of the vital building blocks of sea, sky, & land.
Open Year Round!
Monday - Saturday 10am-5pm • Sun 11am-5pm
