Ten Thousand Waves, Santa Fe — A Japanese Mountain Spa in the High Desert

Japanese onsen culture is one of the more well-documented wellness practices in the world, with research going back decades on the health effects of regular communal bathing. The evidence points to a consistent set of benefits: reduced cortisol, improved sleep quality, lower blood pressure, and improved recovery from muscle fatigue. The temperature contrast protocols used in traditional Japanese bathing — alternating between hot soaks and cooler rinses — also appear to have distinct benefits for cardiovascular tone and immune function.

Ten Thousand Waves doesn't offer the full traditional onsen experience (the water here is treated mountain spring water, not geothermal mineral water), but it captures what matters: the architecture of slowing down, the social norm of silence, and the physical experience of heat immersion in a beautiful environment.

The onsen tradition is built around something spas rarely achieve: an environment where silence is normal, stillness is expected, and being slow is the only way to do it right.

The communal pool at Ten Thousand Waves is clothing-optional by default. This follows the traditional onsen model and is, in practice, straightforward — the norms are clear, the space is well designed, and first-timers typically find it comfortable within minutes.

Private cedar tubs are the better option for a first visit or for those who prefer it. Each is enclosed, fed with the same mountain spring water, and comes with towels, robes, and access to a cold rinse shower. Private tub time is typically 50 minutes. You can add massage or body treatments to the booking, but the tub alone is genuinely sufficient.

What to book

• Communal pool — best value, best for solo visitors comfortable with clothing-optional bathing
• Private tub — better for couples or first-time visitors, quiet and complete
• Private suites — for groups of three to eight; include a pool, sauna, and seating area

Santa Fe sits at over 7,000 feet. The spa is several hundred feet above that. This matters. Heat immersion at altitude has a stronger cardiovascular effect than the same protocol at sea level — heart rate elevates more quickly, dehydration is accelerated, and the transition between hot and cool temperatures is more pronounced.

Drink more water than you think you need. Take the cool rinse between soaks. Leave the pool if you feel lightheaded. These aren't warnings against going — they're context for doing it well. The altitude-and-heat combination, managed carefully, produces a particularly deep sense of relaxation that's harder to replicate at lower elevations.

Ten Thousand Waves earns its reputation. Forty years of refinement shows in the details: the way the property is laid out, the quality of the woodwork, the quiet enforced by good design, the staff who understand what they're running.

The 9.0 / 10 rating reflects a genuinely excellent execution of a specific concept. The property has scale limitations — private tubs book quickly, the communal pool can feel crowded in peak season — and the treatments, while good, are not exceptional. But for the core experience of a Japanese-style mountain soak in a remarkable high-desert setting, nothing comparable exists in the region.

Q: Is clothing required in the communal pool?

The communal pool is clothing-optional, following the traditional Japanese onsen model. The norm is well established and the environment makes it comfortable for most visitors.

Q: How far in advance should I book?

Weekend dates, especially in spring and fall, book out 2–4 weeks in advance. Weekday availability is generally better. Book online as early as possible.

Q: Is the altitude a concern for the hot pools?

Heat immersion at altitude does have a stronger cardiovascular effect. Drink plenty of water, take cool rinses between soaks, and don't rush. Most healthy visitors have no issues.
