About this spring
633-acre historic ranch (1864 stage stop; ex-Bingham Springs Resort that hosted Coolidge and Hoover) in the Blue Mountains on the Umatilla River — 40x60-ft untreated geothermal pool (~93°F). Now a retreat/guest ranch with cabins and lodge. Fee: Pool included with overnight/retreat booking; no day use. Pool access requires a booking — no day use; no cell service.
Bar M Ranch is a 633-acre guest ranch and Christian retreat center in a Blue Mountains valley along the Umatilla River, at 58840 Bar M Lane near Adams, Umatilla County — roughly 30–31 miles northeast of Pendleton via Gibbon, flanked by Umatilla National Forest land and the North Fork Umatilla Wilderness. The site is historically significant: a stage house has stood here since 1864 on the Walla Walla–Boise route, and by the late 1800s the Bingham Springs Resort was a recognized destination that hosted President Calvin Coolidge and then-Secretary of State Herbert Hoover. The property has been owned by Calvary Chapel of Tri-Cities since 2011 and operates as a year-round retreat/conference facility open to church groups, families, businesses, and general guests who book.
The soaking feature is a 40×60-foot untreated outdoor pool fed by a natural geothermal spring emerging at ~93°F and cooling to ~85°F in the pool — comfortably warm rather than hot. A ~133 gpm flow keeps the water naturally refreshed, so no chemicals are required under Oregon standards. The pool area includes changing rooms with showers and a large deck.
Pool access is included only with an overnight stay or retreat/conference booking — there is no day use for independent visitors. Lodging options include cabins, a lodge, and the historic ranch house; on-site recreation covers hiking, a fishing pond, Umatilla River tubing, horseback riding, volleyball/basketball, and a general store. No cell service.

Oregon geothermal context
Oregon splits cleanly in two: Cascade volcanic springs like the Umpqua corridor pools west of the crest, and high-desert basin springs like the Alvord area east of it. Western sites sit in dense wet forest prone to fire closures and winter road washouts; eastern ones are remote sagebrush tubs under enormous skies. Both ends reward checking land-manager alerts before driving out.
What a resort site means here
A resort spring is a commercial operation: developed pools or tubs with controlled temperatures, changing facilities, and usually day-use fees or lodging packages. Expect posted rules (swimsuits, quiet hours, age limits), staff on site, and in many cases required reservations — especially on weekends and holidays.
Best time to visit
May – October (Spring through Fall)Pacific Northwest springs are framed by lush temperate rainforests. Summer brings dry, sunny trail conditions, while autumn provides vibrant foliage and crisp soaking weather.
