About Oasis

A project of the non-profit Better Billings Foundation in collaboration with Harvest Church, Oasis is Billings’ and the surrounding area’s most extensive out door aquatic facility.

With more amenities and opportunities for family fun this exhilarating public facility provides enjoyment for all ages. As an organization we value potential, our desire is that families and youth will recreate and exercise together to improve their overall quality of life. Families just do better when the hang out together and Oasis is a great place to do just that!
