You can soak or swim in many natural hot springs where access is legal — expect variable temperatures, mineral water, clothing rules, and fees that differ from river swimming holes.
- Water temperature
- Often 90°F–104°F in soak zones; cooler mixing pools vary
- Common rules
- No glass, stay on trails, respect clothing policies
- Best regions
- Rockies, Southwest, Cascade Range, parts of Appalachia
- Risk
- Overheating, dehydration, slippery mineral rock

Natural hot springs let you swim or soak in geothermally heated water — often mineral-rich and surrounded by mountain or desert scenery. They overlap with “swimming holes” in trip planning, but the experience differs: temperature, rules, and land management are built around soaking culture, not river current.
How hot springs differ from river swimming holes
| Factor | Hot spring | River swimming hole |
|---|---|---|
| Temperature | Heated underground | Air and snowmelt driven |
| Flow | Pool circulation or creek mix | Open current common |
| Minerals | Iron, sulfur smell possible | Clear runoff water typical |
| Development | Rustic to full resort | Often undeveloped |
| Rules | Soak hours, clothing policies | Access and fire bans |

Types of hot spring access
Wild / primitive pools — Short hike, variable maintenance, pack-it-out ethics. Temperature can scald at the source — test before you settle in.
Forest or park managed sites — May charge day-use fees; vault toilets sometimes present.
Developed resorts — Entry fee, rentals, time limits; best when you want predictable temperature and lifeguard-style oversight (still read rules — not all have lifeguards).
Regional starting points
New Mexico — Taos and Montezuma areas draw soakers year-round; altitude and sun intensity matter as much as pool temperature. See New Mexico listings.
Wyoming — Granite Hot Springs and state-park springs sit in mountain settings with seasonal road access. See Wyoming listings.
Oregon — Cascade springs such as Bagby combine forest hike with soak culture; winter access can require snow travel. See Oregon listings.
Safety at hot springs
- Hydrate — Hot water increases dehydration; bring more water than for a river swim.
- Limit soak time — Especially above 8,000 feet elevation.
- Pregnancy and health conditions — Consult a clinician; hot soaking is not universally advised.
- Slippery decks — Mineral coatings on rock and wood are slick; use footwear.
- Alcohol — Combines poorly with heat and remote access roads.
Planning your visit
- Read our location page for fees, road status, and clothing rules.
- Check forest or park alerts for fire bans and road closures.
- Arrive early on weekends — parking fills at famous springs.
- Pair with a cold river swim only if you understand shock risk — “hot then cold” is not for everyone.

Frequently asked questions
Can you swim in natural hot springs?
Many hot springs allow soaking or swimming in designated pools, but rules vary. Some are soak-only, clothing-optional, or closed during high runoff. Check each site and land manager.
What is the difference between hot springs and swimming holes?
Hot springs are geothermally heated, often mineral-rich, and temperature-managed by source and pool design. Classic swimming holes are ambient river or creek temperature.
Are Wyoming hot springs free?
Some are on public land with low or no fees; developed springs charge for maintenance and access. Verify on the location page and agency site before you go.
