Medical Hot Springs
Medical Hot Springs emerges at 140°F in Union County's forested mountains, requiring a 289-meter walk from Medical Springs Highway at 3,523 feet elevation. The spring's name reflects historical belief in therapeutic properties of mineral-rich thermal water. Located near the town of Union, the site maintains a 93-degree differential above ambient air in a climate averaging 47°F annually with nearly 25 inches of precipitation and 84 inches of snow.
The spring occupies mid-elevation forest terrain on the western approaches to the Eagle Cap Wilderness, where mixed conifers including Douglas fir, grand fir, and ponderosa pine dominate. The setting receives substantial winter snowpack and summer thunderstorm moisture, supporting dense forest vegetation. Topography features moderate to steep slopes typical of Oregon's Blue Mountains, with volcanic and granitic bedrock underlying forested ridges. The nearest wilderness boundary lies within reasonable hiking distance for backcountry exploration.
Medical Springs derives its name from Native American and early settler use for therapeutic bathing, a common pattern across Oregon's thermal features. The town of Medical Springs, nearby on Highway 203, takes its name from the same resource. No large-scale commercial resort developed at this location despite the high temperature and historical use. Current access reflects informal trail-based recreation rather than commercial infrastructure. Documentation of specific historical details remains limited in published sources.
The 289-meter approach requires moderate hiking ability on uneven terrain. Winter snowpack of 84 inches limits access from December through April without snowshoes or skis. Buck Creek Campground, 15 kilometers distant near the Eagle Cap Wilderness boundary, offers primitive camping for extended stays. Summer and early fall provide optimal windows. Source temperature of 140°F requires caution; soaking occurs in pools where thermal discharge mixes with cooler water. Check Forest Service status; some Oregon springs close periodically.

Located on the western side of the Eagle Cap Wilderness and very close to the wilderness boundary, the Buck Creek Campground/Trailhead was built to meet the needs of both wilderness trail users and overnight campers.
