Mills Spring Ranch was donated to the Wyoming Conference of Seventh-day Adventists by the Mills Family of Casper, Wyoming in 1964.  It is currently owned and operated by the Rocky Mountain Conference of Seventh-day Adventists.
The camp is located on top of beautiful Casper Mountain.  With approximately 200 acres of wilderness forest and meadows, adjacent to unimproved private and public lands, there is plenty of room to explore God’s natural world year-round.


Our Mission is to provide a Retreat Center in nature where one can learn more about creation and our Creator.

Established in 1964, Mills Spring Ranch has provided the State of Wyoming and surrounding areas a wonderful area of beauty, peace and rejuvenation.
