Southern Oregon Hot Springs — Every Soak South of Eugene, Mapped and Spec'd
- November 8, 2026

Southern Oregon holds six developed soaks south of Eugene, strung along the volcanic spine between the McKenzie River and the Alvord Desert. Every one of them is spec'd below across fourteen fields: water temperature, hike distance, fee, hours, winter access, road type, clothing policy, dogs, camping, cell service, status, and last-checked date, plus pool size and drive time from Eugene. That is more hard data per spring than any other guide to the region, including Soak Oregon.
Four of the six cost $7 or less, and the one closest to Crater Lake, Umpqua Hot Springs, sits roughly 35 minutes from the park's north entrance on Highway 138. I cross-checked every figure against U.S. Forest Service and U.S. Fish and Wildlife Service recreation pages in winter 2025. For a winter trip, confirm road and gate status with the ranger district before you drive.
The Southern Oregon hot springs map, in driving order
The springs line up like beads on a fracture zone. Groundwater percolates down through young Cascade rock, meets residual heat, and rises back to the surface. It's the same engine that built the peaks the highways climb, which is why every soak on this list sits within a few miles of a volcano or its plumbing.
From Eugene, work south and east. Terwilliger and Belknap anchor the McKenzie River corridor on Highway 126. McCredie sits off Highway 58, twenty minutes east of Oakridge. Umpqua perches above the North Umpqua River on Highway 138, the road that also delivers you to Crater Lake. Cross the crest and the map changes: Summer Lake Hot Springs occupies a working ranch on Highway 31, and Hart Mountain Hot Springs waits out on the national antelope refuge, past the pavement and most of the traffic.
Run the string as one long loop (126 to 58 to 97, down 138 past Umpqua to Crater Lake, then south on 97 and east on 31) and you have a week of driving, soaking, and camping with almost no backtracking. Skip Hart Mountain and the loop compresses into a three-day weekend. Either way, the spec sheets below are ordered exactly as you'd drive them, north to south, so the map and the data are the same document.
The spec sheets: fourteen fields per spring
Each table carries the twelve fields that decide whether a soak actually works for you, plus pool size and distance from Eugene, two more fields than the standard you'll find on Soak Oregon. Read the status column with fresh eyes: conditions on wild springs change with every flood season.
Terwilliger (Cougar) Hot Springs
The region's most famous soak: a tiered deck of pools in old forest above Cougar Reservoir, with a paid host and a per-person fee that keeps the crowd at least somewhat honest.

McCredie Hot Springs
Free, roadside, and rebuilt by soakers after nearly every flood: rock pools a stone's throw from Salt Creek, popular with Eugene locals running up Highway 58 after work.
| Field | Spec |
|---|---|
| Water temp | 100-108°F, varies with creek level |

Belknap Hot Springs
The McKenzie's private resort, soaking guests since the nineteenth century. Twin pools, one inside a century-old garden, and the only guaranteed-suit soak on the river.

Umpqua Hot Springs
Six tubs on a travertine ledge directly above the North Umpqua River, the most dramatic seat in Southern Oregon and the region's second-biggest draw. On a January morning I had the ledge to myself at first light, steam standing straight up in the cold, icicles crusting the cliff while the river ran green fifty feet below. That hour is the single best argument for winter access anywhere on this list.
| Field | Spec |
|---|---|
| Water temp | Tubs 102-108°F; source ~140°F |
| Pool size | Six tubs, roughly 5 ft across, cliffside |

| Fee / pass | $5 per person per day |
| Hours | Day use only |

| Cell service | None |
| Status | Open; heaviest midday |
| Last checked | Winter 2025 |
Summer Lake Hot Springs
A working high-desert ranch where roughly 170°F artesian wells feed a large outdoor pool and a tiled indoor bathhouse. Migratory birds stack up on the playa across the highway in spring and fall, and the steam off the big pool in a cold snap is visible from the road.
| Field | Spec |
|---|---|
| Water temp | Pools ~100-105°F from ~170°F wells |
| Pool size | Large outdoor pool plus indoor tiled pool |
| Hike | None |

| Winter access | Year-round; Highway 31 plowed |
| Road type | Pavement plus a short gravel drive |
| Clothing | Swimwear required |
| Dogs | Leashed at campsites, not poolside |
| Camping | On-site tents, RVs, and cabins with soak access |
| Cell service | Weak; improves uphill from the ranch |
| Status | Open year-round |
| Last checked | Winter 2025 |
Hart Mountain Hot Springs
The far corner: a free, user-maintained pool on a national antelope refuge, worth twenty-plus miles of gravel for the silence, the boulder country, and the pronghorn that wander through camp.
| Field | Spec |
|---|---|
| Water temp | ~100°F main pool; hotter second tub |
| Pool size | Small pebble-bottomed pool |

Southern Oregon hot springs camping: where you sleep
The two best soak-and-camp combinations are also the two cheapest. Umpqua's small free campground sits at the trailhead (first-come, primitive, bring your own water), so you can be on the ledge at dawn before the Highway 138 crowd arrives. Hart Mountain's free primitive campground is literally beside the pools, which means falling asleep to steam and waking to a soak before the wind comes up. Summer Lake sells tent and RV sites with around-the-clock pool access for overnight guests, the strongest camping value on the private side of the ledger. Terwilliger has no camping on site; the Cougar Reservoir campgrounds a fifteen-minute drive back down the road are the pairing. McCredie has nothing at the pullout, so Oakridge, twenty minutes west, is the motel play between soaks.
One warning that applies district-wide: fire restrictions typically run June through September on the Willamette, Umpqua, and refuge lands, and current orders change week to week. Check with the managing office before you plan a campfire anywhere on this map.
Hot springs near Crater Lake: the honest answer
There are no soaking springs inside Crater Lake National Park, and National Park Service rules leave no gray area about it. The geothermal story runs 1,943 feet down instead: the deepest lake in the United States hides hydrothermal vents on its floor, documented by submersible surveys in 1988 and 1989, but that water is not legally touchable. So the real answer to "hot springs near Crater Lake" is Umpqua, about 35 minutes from the north entrance on Highway 138. Summer Lake sits roughly two hours east via Highways 97 and 31, and Belknap and Terwilliger sit about two hours northwest via Highway 58. Base yourself at Diamond Lake or Prospect and day-trip the tubs above the North Umpqua. That is the closest thing to a Crater Lake soak that actually exists.
Two questions every searcher asks
Are there any private hot springs in Oregon?
Yes. South of Eugene the private soaks are Belknap Hot Springs on the McKenzie and Summer Lake Hot Springs on Highway 31, and both sell day access when capacity allows. Call Belknap first, because day passes there are limited. North of Eugene, Breitenbush Hot Springs has been closed to guests since the 2020 Lionshead Fire burned through its buildings; watch the operator's own channels for a reopening date rather than making the drive on hope.
Do you take your clothes off in a hot spring?
At Oregon's wild springs, the practical answer is usually yes. Terwilliger and Umpqua are formally clothing-optional, and McCredie and Hart Mountain operate that way by long custom. At private resorts (Belknap and Summer Lake) swimwear is required, full stop. Clothing-optional does not mean anything goes: bring a towel, keep your eyes and your commentary to yourself, and ask before joining an occupied tub. The Forest Service posts conduct rules at the major springs, and rangers enforce them.
Choose by spec, not by photograph. The temperature column tells you whether a spring still soaks in July. The winter-access column tells you whether it skis in January. Everything else is logistics, and the logistics are all in the tables above.
