3 Arizona Hot Springs Regions

Arizona’s hot springs offer diverse experiences, from primitive backcountry pools to ritzy resorts. This guide organizes the state’s hot springs by 3 regions, providing detailed descriptions of each location to help visitors plan their geothermal adventures.

  1. Northwest Arizona: Goldstrike Hot Springs, Arizona/Ringbolt Hot Springs
  2. Central Arizona: Kaiser Hot Springs, Verde Hot Springs, Sheep Bridge Hot Springs, Castle Hot Springs, El Dorado Hot Springs
  3. Southeast Arizona: Essence of Tranquility, Roper Lake State Park, Hot Well Dunes

Arizona’s hot springs are concentrated in regions with active geothermal activity, often near fault lines or volcanic features. Key areas include:

1. Northwest Arizona

Goldstrike and Arizona Hot Springs (Ringbolt Hot Springs) lie within the Lake Mead National Recreation Area, where geothermal waters emerge along the Black Canyon near the Colorado River. The springs form due to heated groundwater rising through fractures in the bedrock, creating pools with temperatures up to 120°F.

Goldstrike Hot Springs (Black Canyon, near Nevada border)

Located just across the state line in Nevada but accessible from Arizona, these pools range from 100°F to 109°F and are nestled within Black Canyon’s volcanic landscape. The hike involves technical scrambling and rope-assisted sections, making it ideal for adventurous visitors.

  • Access: A strenuous 6-mile round trip hike starting near Hoover Dam; closed May 15–September 30 due to extreme heat risks.
Arizona Hot Springs AKA Ringbolt Hot Springs (Lake Mead National Recreation Area)

Situated along the Colorado River in Black Canyon, this series of three-tiered pools is heated by geothermal activity, with temperatures ranging from 85°F to 120°F. The pools are separated by sandbags and surrounded by volcanic rock walls within a dramatic desert canyon.

  • Access: A strenuous 3–6 mile hike via White Rock Canyon Trail or Hot Spring Canyon Trail; includes a 20-foot ladder climb.
  • Facilities: Primitive camping is allowed along the Colorado River; pit toilets are available downstream of the springs.
  • Best Time to Visit: October to April (closed May 15–September 30).

2. Central Arizona

Kaiser, Verde, and Sheep Bridge Hot Springs are situated in this region, along with Castle and El Dorado Hot Springs (closer to the valley), where tectonic activity facilitates geothermal outflow. The public hot springs in this area often appear near riverbanks, with water temperatures moderated by mixing with cooler surface flows.

Kaiser Hot Springs (near Wikieup)

A hidden gem in Kaiser Canyon, this site features two rock-walled basins fed by geothermal seepage at 99–100°F. The pools are surrounded by rugged desert scenery and offer a tranquil soaking experience.

  • Access: A moderate 1.5-mile hike through sandy terrain; high-clearance vehicles are recommended for the dirt road approach.
  • Facilities: None onsite; primitive camping allowed nearby.
  • Nearby: Burro Creek Campground (12 miles south) offers vault toilets and picnic tables ($6/night).
Verde Hot Springs (Tonto National Forest)

Once part of a historic resort destroyed by fire in the mid-20th century, Verde Hot Springs now consists of two main pools fed by geothermal seeps at temperatures up to 104°F. The site is surrounded by scenic cliffs along the Verde River5.

  • Access: A moderate 2-mile hike from Fossil Creek Road that includes a river crossing. High-clearance vehicles are recommended for the rough access road.
  • Facilities: Primitive camping allowed nearby; no developed amenities.

The spring provides a secluded soaking experience with clear, warm water at approximately 100°F. The tub is lined with river rocks and can comfortably fit 2-3 people.

  • Access: Reached via a challenging 45-mile drive north from Carefree, AZ. Take Cave Creek Road/Forest Road (FR) 24 for about 33 miles, then turn right onto FR 269 for the final 12 miles to Sheep Bridge. High-clearance 4x4 vehicles are strongly recommended due to rough, unpaved roads.
  • Facilities: No developed amenities. Dispersed camping is allowed for up to 14 days in the surrounding area.
Castle Hot Springs (Morristown)

Located in a secluded canyon, Castle Hot Springs is a luxury resort offering exclusive access to its geothermal pools. The springs produce 200,000 gallons of water daily at temperatures up to 115°F, making them among the hottest non-volcanic springs in the world.

The resort features three pools ranging from 86°F to 106°F, surrounded by lush greenery and desert cliffs.

Seasonal Considerations and Soak Timing

  • Optimal Seasons: Spring (March–May) and fall (September–November) offer mild daytime temps (65–86°F) and reduced crowds.
  • Summer Risks: Many springs, including Arizona Hot Springs, close due to extreme heat (temps >110°F) and flash flood risks.
  • Winter Visits: Possible but require cold-weather gear; nighttime temps often dip below freezing.

Arizona Hot Springs Safety and Health Considerations

  • Waterborne Pathogens: Avoid submerging your head; *Naegleria fowleri* amoeba infections, though rare, can occur.
  • Flash Floods: Check weather forecasts; avoid canyons during rainstorms.
  • Heat Exhaustion: Carry 2–3 liters of water per person for hikes.
  • Leave No Trace: Pack out all trash and human/pet waste.

Arizona’s public hot springs cater to diverse preferences, from the rugged adventurer seeking solitude in Verde Hot Springs to families enjoying the developed amenities of Roper Lake.

While accessibility varies widely, strategic planning around seasonal closures and trail conditions ensures a rewarding experience. For those willing to navigate desert trails, the therapeutic rewards of soaking in these geothermal oases are unparalleled. ♨️
