8.5 Outstanding overall · Spa: Thermal Complete · guests rate it 4.7 on Google
top 2% of 116 hotels scored, October 2026
The thermal water is the spa here, and the staff is why guests return.
Three spring-fed pools stay open day and night, and guests praise staff by name. Springs and treatments serve registered overnight guests only. The resort stayed open through summer 2026, a first, and has not said it will continue. It sits an hour or more from Phoenix, the last seven miles unpaved. No hotel page publishes a spa footprint. Peak night runs 3.28 times the Phoenix median. Right for couples wanting the water and an all-in rate; wrong for day-spa seekers, children, pets or one-night stays.

Rate notes, fees and tax
Peak from $2,490 a night (27 Feb 2027); off-season from $1,390 a night (21 Aug 2027).
- Peak
- 27 Feb 2027 from $2,490 room, $2,648.12 all-in (3-night minimum). The Best Available Rate, which carries free cancellation until 14 days before arrival at 3 p.m. hotel time, a 50 percent penalty including tax after that, and full charges for no-shows and early departures, prices the Sky View Cabin, King, 378 sq ft, the cheapest room type, read from the 26 February to 1 March 2027 stay (room $7,245, tax $460, $7,705 for three nights, a 50 percent deposit at booking).
- Off-Season
- 21 Aug 2027 from $1,390 room, $1,478.27 all-in (2-night minimum). The same Best Available Rate terms and the same Sky View Cabin, King, 378 sq ft apply, read from the 20–22 August 2027 stay (room $2,780, tax $177). Summer 2027 is on sale, and the resort's first July–August season ran in 2026.
- Rate notes
Fee stack: no resort fee; Yavapai County sales tax 6.35% of the room total; all meals, snacks and soft drinks, gratuities and service charges, valet and self-parking, EV charging and WiFi included; 20% service charge on purchased beverages and purchased amenities; 50% deposit at booking Rates correct as of October 2026 from the resort's own booking engine for two adults, one room, the Best Available Rate, per-night figures read from the shortest bookable stay (3 nights in February, 2 nights in August) because a single night returned no rooms, the rate being all-inclusive of all meals, gratuities, many resort activities and unlimited hot-springs access, with the all-in figure the room plus 6.35 percent Yavapai County sales tax.
Whether summer opening will continue beyond 2027 is not stated by the hotel, so a pricing-review trigger stays active.
Spa Treatments
Spa treatments excel, led by Watsu in the warm springs, a flowing water-based bodywork session. Watsu runs $295 for 60 minutes. A 60-minute massage at $255 compares with a $207 median across the other 8 Phoenix hotels that publish a price. Treatments are bookable by registered guests only, and the menu is silent on gratuity while the hotel's pages disagree. A Google guest, September 2024, wrote, "The massage was better than any I’ve had - at any 5 star resort."
Spa Facilities
The spa's three spring-fed soaking pools stay open day and night for overnight guests, and a cold plunge completes the circuit. Its hottest pool runs 104 to 108°F, and the springs stay open 24 hours to registered overnight guests only. No sauna or steam room appears on any hotel page, against 8 of the other 9 Phoenix hotels that list one. No hotel page publishes a treatment-room count or square footage. A Google guest, September 2024, wrote, "You spend 15 minutes in the hot spring, followed by a cold plunge."
Wellness Programs
Castle Hot Springs puts at least 10 classes a week in the rate on its autumn schedule, with hikes and farm tours. Ten is a floor, leaving out any morning classes the schedule does not list, and no winter timetable is published. Guided hikes, farm tours, paddleboard yoga, sound baths and qigong come included. 34 of the 46 other spa hotels that publish a class count include fewer, and 23 include none. Practitioner sessions are charged as spa treatments, never included.
Staff & Service
Staff at Castle are praised by name year after year, from the sommelier to a massage therapist, and rarely criticized. Guests praised the sommelier by name from 2020 to 2026. Service complaints run 3.0% of guest reviews against a median of 11.5% across 21 other spa hotels. Guests return to four massage therapists by name, where the median spa hotel has one. A Google guest, September 2024, wrote, "The entire staff were the most friendly and accommodating I’ve ever met."
Experience
Guests rate Castle higher than any other spa hotel we have measured, though the unpaved road is the main drawback. Reviews average 4.83 out of 5 across 123 recent TripAdvisor and Google reviews, against a median of 4.47 across 21 other spa hotels. Ratings for the past year read higher than for the year before. Seven unpaved miles finish the drive, the downside guests name most, and Phoenix is an hour or more away. A TripAdvisor guest, January 2026, wrote, "Everything and everyone was top tier."
Value for Money
A night at Castle covers meals, many activities and the springs, though its peak night is Phoenix's dearest. A peak Saturday, 27 February 2027, priced at $2,648.12 a night all-in, runs 3.28 times the typical peak night of the 9 other Phoenix hotels, which charge room, fee and tax without meals, so not like for like. Treatments, alcohol and premium excursions cost extra. A TripAdvisor guest, June 2026, wrote, "the place is not inexpensive, even with the off-season rates which we enjoyed," then credited the food and activities.

About This Hotel
Castle Hot Springs is seven unpaved miles out, its three soaking pools, Watsu grotto and cold plunge fed by its own thermal water; no day passes or under-18s. The water is the spa.
The Spa, Specifically
The circuit is the canyon itself: a 104-to-108-degree First Pool, a 98-to-102-degree second, and a swimming-size 75-to-90-degree third pool, plus a cold plunge guests have measured at 44 and 39 degrees (“a plunge pool at 44 next to the hottest pools,” TripAdvisor, October 2024). Castle Hot Springs calls the sequence a contrast soaking circuit, and it works as a hydrotherapy circuit with spring water doing the heating. A March 2026 Spascape Substack piece counts three treatment cabanas and a lounge cabana, but the resort’s own pages publish no count and no square footage. Prices, by contrast, are printed for every in-spa treatment: 60/90/120-minute massages at $255, $385 and $515, Watsu in the springs at $295 and $445, facials at $255 and $385, body rituals from $255 to $515, and the two-hour signature Mineral Scrub & Full-Body Massage at $515. Robert, who gives massage and Watsu, draws praise in seven reviews from 2020 to 2026, the most named of four therapists guests return to. Press and Wikipedia date the resort to 1896 and record a 1976 fire and a February 2019 reopening.
Who’s Right, Who’s Wrong
Book this if the water and the quiet are the trip: couples and solo travelers buy 24-hour springs, three meals a day, a 575-square-foot Spring Bungalow or 378-square-foot Sky View Cabin, and a staff guests name year after year, with meal and activity gratuities included. Winter stays carry a three-night minimum, so the price buys seclusion rather than square footage. Skip it if you want a day spa, children under 18, or a one-night stay.
Where It Sits in the Phoenix Market
Castle Hot Springs is the only Phoenix property we’ve scored with natural thermal water on its own grounds, and its peak night is the dearest of the ten Phoenix hotels, at 3.28 times the median of the other 9. It is the one Phoenix hotel with no resort fee and no published spa service-charge percentage. Across the other 9, resort fees run $15 to $80, and the 8 that state a spa service charge set it at 19 to 22 percent. Three of the other nine publish a spa footprint (17,500 to 28,000 square feet) and eight have a sauna or a steam room. This resort has neither. Tierra Luna at the Biltmore counts 12 treatment rooms in 28,000 square feet, and Aji Spa at the Sheraton counts 17. At Royal Palms, a $50 resort fee comes with a 20 percent spa service charge.

Is the Castle Hot Springs Spa Worth the Price?
Yes, for couples and solo adults after silence and mineral water. A night in the entry-level Sky View Cabin runs about $1,478 in August to $2,648 in February all-in, covering meals, gratuities, many activities and 24-hour springs. Treatments cost extra. Wrong for day-spa seekers, square-footage shoppers, under-18s, pets or one-night stays.
When to Book the Castle Hot Springs
Winter stays have needed three nights on the resort's booking engine and summer stays two, and a single night returns no rooms, so plan the trip around the minimum. An August night has priced well below a February night for the same cabin. A 50 percent deposit secures the room, with free cancellation up to 14 days before arrival on the flexible rate. Book treatments two weeks ahead through the guest-experience team.

A Watsu grotto hosts the Watsu treatment, and a cold plunge tub, which guests have measured at 44 and 39 degrees, pairs with the hot soaks. Lithium, magnesium, iron, sodium and calcium give the water its mineral profile.

All meals including the nightly five-course tasting dinner, snacks and soft drinks, Bar 1896 food, gratuities and service charges, valet and self-parking, EV charging, WiFi, cruiser bikes, guided activities and 24-hour springs access.

Current prices sit in the Pricing and Availability section and on the resort's booking engine. Minimum stays on the resort's booking engine have been three nights from January to March and two nights in August, and a single night returns no rooms. A 50 percent deposit lands at booking.
Does the Resort Stay Open Through the Summer?

Sky View Cabins carry a private outdoor soaking tub, and Spring Bungalows add a stone soaking tub.
What Is the Dining Like?
Dinner at Harvest is a nightly five-course tasting menu, and Bar 1896 serves food and drinks. A farm of over three acres and more than 150 crops each season supplies the kitchen. Meals, snacks and soft drinks are included, while alcohol is an add-on.
What Are Check-In and Check-Out Times?
Check-in is at 4:00 p.m. and check-out at 11:00 a.m.
What About Parking and Getting Around the Resort?
Valet and self-parking are both included, along with EV charging. A 24-hour courtesy cart covers the roughly seven-minute uphill walk from the lodge to the springs. Driving requires the unpaved last seven miles, for which the resort recommends a high-clearance vehicle.
