Sources you can check

A useful directory should explain where a fact came from, what it establishes and what remains unknown.

How this collection was built

We reviewed 16 destinations using published visitor information. A separate acquisition of DOGAMI’s 690 geothermal inventory records helped identify historical names and locations. Fifteen destination records were matched to that inventory; Mickey uses BLM’s recreation coordinates without a forced one-to-one geological match.

Geothermal records are not a list of public bathing sites. We did not turn every vent, well or historical measurement into a recommended destination. Hart Mountain’s visitor spring was matched to the Antelope Hot Springs cluster, rather than a different record named Hart Mountain several miles away.

Which source answers which question?

• Access and restrictions: the land manager or official operator, where retrievable.
• Prices and reservations: the operator’s published terms; conflicting prices remain flagged.
• Visitor context: Oregon and regional tourism organizations, labelled on the profile.
• Location and geological identity: DOGAMI records or recreation-site coordinates. These are not parking or accessible-entrance coordinates.
• Trip decisions: original comparisons of these facts, not copied reviews or claimed personal experience.

Freshness and limitations

The current review date is October 12, 2026. We do not run a live closure, weather or water-quality feed. Seasonal descriptions do not establish today’s opening status. For Umpqua, a blocked Forest Service fetch meant using Travel Oregon for visitor facts; current fees remain unverified. Bagby’s USFS page reported a wildfire closure during review. Belknap and Kah-Nee-Ta have dated or conflicting notices that are preserved in their guides.

Historical source-water temperatures are not displayed as bathing temperatures. Missing data is labelled unverified. Check official sources again before travel, especially after severe weather or wildfire activity.
