Umpqua National Forest, in southern Oregon's Cascade Range, covers an area of 983,129 acres in Douglas, Lane, and Jackson counties, and borders Crater Lake National Park. The four ranger districts for the Forest are the Cottage Grove, Diamond Lake, North Umpqua, and Tiller ranger districts. The Forest is managed by the United States Forest Service, headquartered in Roseburg. Stands of western hemlock, true fir, Douglas-fir and cedar transition to lower-elevation forests of mixed conifers and hardwoods. Timbered valleys of old-growth ponderosa and groves of oak separate mountains like the 9,182-foot Mount Thielsen and the 8,363-foot Mount Bailey. Notable geologic features include volcanic basalt and andesite monolithic spires with descriptive names like Eagle Rock, Rattlesnake Rock, and Old Man.

Umpqua Hot Springs is a geothermal pool located along the North Umpqua River at 2,640 feet elevation. Two oval pools are available for soaking, the larger having a solid rock bottom and the smaller a bottom of coarse sand. The larger is five by eight feet and 110 °F (43 °C), and is covered by a wooden enclosure. The upper pool is smaller but slightly warmer, measuring four by five feet and 112 °F (44 °C). Both pools are approximately two and a half feet deep. Umpqua is clothing optional.
