11 Best Hot Springs in Hawaii (2026 Guide + Hidden Gems)

Hot Springs in Hawaii offers an extraordinary collection of geothermal wonders shaped by the islands’ active volcanic geology. Among the most famous destinations, Pohoiki Warm Springs stands out as Hawaii’s premier accessible geothermal site, featuring multiple thermal pools along a stunning black sand beach. 

The historic Ahalanui Warm Pond was once beloved before the 2018 eruption, while Queen’s Bath on Kauai and the Pools of Ohe’o in Maui attract thousands seeking sun-warmed waters. Private retreats like Sacred Source Hot Springs and Wai Ola Springs provide exclusive mineral-rich soaking experiences. 

Through my extensive research at Soak Destinations, I’ve compiled this comprehensive guide to help you discover Hawaii’s most captivating thermal destinations.

1. Pohoiki Warm Springs

• Location: Isaac Hale Beach Park, Puna District, Big Island, Hawaii
• Cost: Free
• Water Temperature: 75°F – 100°F (varies by location and tide)
• Weather / Best Season: Year-round; weekdays and early mornings (before 9 AM) recommended to avoid crowds
• Review: 4.5/5
• Official Website: hawaiicounty.gov/departments/parks-and-recreation 

Pohoiki Warm Springs emerged as Hawaii’s premier geothermal destination following the 2018 Kilauea eruption. The volcanic activity created several new thermal ponds along a stunning black sand beach. 

These pools formed when lava flows trapped heated spring water behind natural sand barriers. The original warm pond sits in a collapsed lava tube within the jungle, reaching temperatures around 100°F, while newer beachfront pools offer shallower, knee-deep soaking options perfect for relaxing without full immersion.

How to Get There

• From Hilo: Highway 11 south → Highway 130 toward Pahoa → Right on Highway 137 to end (45 minutes)
• Parking: Fills by 10 AM on weekends. Arrive early or visit weekdays.

Choosing Between the Five Pools

• Northernmost pool (near boat ramp): 90-95°F, most protected from ocean
• Second pool: 85-88°F, balanced temperature
• Middle pools: 78-85°F, fluctuates with tide
• Southern pools (near beach): 75-80°F, perfect for extended swimming

Morning visits before 9 AM find pools at peak warmth. The northernmost pool has a sudden 7-foot drop-off, while middle pools offer gradual entries for families.

Why This Is Hawaii’s Last True Geothermal Spring

Pohoiki is the only publicly accessible location where volcanic heat rises directly from deep within Earth. The water chemistry reflects geothermal origin with slightly elevated mineral content and subtle sulfuric notes—this is living geology you can experience.

Post-Eruption Facilities: What’s Available Now

Available amenities:

• Functioning portable toilets
• Outdoor showers for rinsing
• Paved parking (50 vehicles)
• Operational boat ramp
• Picnic tables under palm groves
• No changing facilities, food vendors, or equipment rentals

What Visitors Say: Recent reviewers praise the unique geothermal experience and beautiful setting. Common complaints include weekend crowding and lack of signage about which pools are warmest.

2. Sacred Source Hot Springs

• Location: Off-grid retreat center, Puna District, Big Island (by reservation only)
• Cost:  $250-400/night depending on accommodation
• Water Temperature: 95-102°F (geothermal source)
• Weather / Best Season: Year-round (private facility)
• Official Website: sacredsourcesprings.com 

Update: The Sacred Source Hot Spring resort is temporarily closed.

Sacred Source Hot Springs is Hawaii’s only true hot spring retreat center offering private, managed geothermal soaking. Unlike coastal warm ponds, this off-grid property features natural mineral water heated by volcanic activity deep underground, maintaining temperatures between 95-102°F. 

The 10-acre organic farm setting provides multiple soaking tubs filled with mineral-rich geothermal water containing over 400 minerals. Access requires advance reservation for retreats, group events, or private soaking appointments, offering a clean, uncrowded alternative to public thermal pools.

How to Get There

• From Hilo: 45 minutes via Highway 11 and 130 toward Pahoa. Detailed directions upon booking confirmation.

The Private Geothermal Experience

Sacred Source Springs offers what’s impossible elsewhere in Hawaii—private, controlled-temperature geothermal hot springs with excellent facilities. Property sits above geothermal aquifers with developed soaking pools fed by volcanic hot water maintaining consistent therapeutic temperatures. Completely off-grid solar/geothermal powered retreat.

What $250-400/Night Includes

Included amenities:

• Private accommodation (cabins to geodesic domes)
• Unlimited access to multiple temperature-varied pools
• Outdoor showers, composting toilets
• Common areas, gardens, meditation areas, trails

NOT included:

• WiFi, TV, air conditioning
• Restaurants or meal service (kitchen facilities for self-catering)

Retreat Philosophy

Attracts yoga retreats, wellness groups, individuals seeking digital detox. Atmosphere leans toward spiritual wellness with optional yoga, meditation, healing workshops. Can simply soak without participating in programming, though overall culture definitely spiritual-leaning.

Booking Requirements

• Book far in advance—fills weeks/months ahead
• Minimum 2-3 night stays typically required
• Deposit required, strict cancellation policy
• Email/phone communication only

What Visitors Say: Praise authentic geothermal experience and peaceful setting. Some note facilities more rustic than photos suggest. Worth cost for those seeking retreat experience but disappointing if expecting resort amenities.

3. Pools of Ohe’o (Seven Sacred Pools)

• Location: Haleakala National Park, Oheo Gulch, East Maui (15 minutes south of Hana)
• Cost: $30 per vehicle (Haleakala National Park entrance fee, valid for 3 days)
• Water Temperature: Cool to moderately warm (sun-heated)
• Weather / Best Season: Year-round; early morning visits recommended; swimming restrictions may apply
• Reviews: 4.5/5
• Official Website: Haleakala National Park

The Pools of Ohe’o consist of seven tiered waterfall-fed pools cascading down volcanic slopes into the Pacific Ocean. Formed from igneous rock that retains solar heat, these pools offer a refreshing mountain spring experience rather than traditional geothermal heating. 

The stunning rainforest setting and dramatic ocean views make this one of Maui’s most photographed locations. The National Park Service frequently restricts swimming due to flash flood risks and slippery conditions, but the scenic overlooks alone justify the visit.

How to Get There

• From Kahului: Road to Hana (2.5-3 hours), 10 miles past Hana town. 600+ curves, 50+ one-lane bridges.
• Parking: Fills by 10 AM peak season. Arrive early or after 3 PM.

Beyond the Pools: Hiking the Bamboo Forest

The Pipiwai Trail is the real attraction—a 4-mile roundtrip hike to 400-foot Waimoku Falls through an otherworldly bamboo forest. Budget 2.5-3 hours. Well-maintained with boardwalks, though strenuous enough to deter crowds.

Why ‘Seven Sacred Pools’ Is a Misnomer

• Actually 20+ pools, not seven
• “Sacred” was 1940s hotel marketing, not authentic Hawaiian culture
• Proper name: Ohe’o Gulch (native fish that once thrived here)

What You Can Still Experience

Available activities:

• Multi-tiered waterfall viewing from overlooks
• Kuloa Point Trail (coastal views, historical sites)
• Educational exhibits at visitor center
• Photography opportunities (afternoon light best)
• Quieter alternative to Haleakalā summit

What Visitors Say: Those focusing on hiking rave about the experience. Visitors expecting swimming leave disappointed. Many note online info fails to prominently mention the swimming ban.

4. Reed’s Bay (Ice Pond)

• Location: Reed’s Bay Beach Park, Hilo, Big Island (off Banyan Drive)
• Cost: Free
• Water Temperature: Unique mix of warm ocean water (top layer) and cold freshwater springs (bottom layer)
• Weather / Best Season: Year-round; weekdays less crowded
• Official Website: Hawaii County Parks

Reed’s Bay, locally known as “Ice Pond,” offers a fascinating thermal experience where underwater freshwater springs create distinct temperature layers. Swimmers experience warm ocean water at the surface while cold spring water chills the lower body—an unusual and refreshing sensation. 

The bay’s calm, protected waters make it ideal for families with children, paddleboarding, and kayaking. Located just steps from Hilo’s hotel district along scenic Banyan Drive, the park features shaded picnic areas and resident Hawaiian geese (nene), the endangered state bird.

How to Get There

• From Hilo Airport: 5 minutes via Highway 11 and Banyan Drive. Park in Lili’uokalani Gardens lot. Short walk to swimming area.

The Gentle Alternative to Pohoiki

Reed’s Bay offers calm, protected, family-friendly swimming in scenic bay surrounded by banyan trees. Noticeably warmer than ocean due to underground freshwater springs—pleasantly warm rather than hot. Urban setting in downtown Hilo means convenient access without remote driving.

Where Freshwater Meets Ocean

Multiple underground springs create distinct warm zones. Swimmers feel transition points between warm pockets and cooler bay water. Slightly hazy visibility but snorkeling possible. Mixing zone supports freshwater gobies and marine fish coexisting.

Family-Friendly Swimming

Popular with locals for children—gradual slope, calm water, no strong currents. Adjacent Lili’uokalani Gardens provide restrooms, picnic areas, Japanese-style gardens with koi ponds.

What Visitors Say: Locals appreciate convenience. Tourists sometimes find it underwhelming versus dramatic photos of other springs but acknowledge it’s perfect for quick Hilo swimming.

5. Queen’s Bath – Kauai

• Location: Princeville, Kauai (Kapiolani Loop)
• Cost: Free
• Water Temperature: Sun-warmed (temperatures vary seasonally)
• Weather / Best Season: Summer months (June-September); avoid during high surf and rainy season (November-April)
• Review: 4.5/5

Update: The Queen’s Bath is temporarily closed.

Queen’s Bath is a dramatic tidal sinkhole enclosed by volcanic rock formations with breathtaking ocean vistas. This sacred site, historically reserved for Hawaiian royalty, features igneous rocks that capture and retain the sun’s warmth. 

The pool includes a small waterfall and offers a unique thermal experience. However, visitors must exercise extreme caution as dangerous “sneaker waves” have caused fatalities. Always check surf reports before visiting, and never venture here during high tide or rough ocean conditions.

How to Get There

• From Lihue: Highway 56 north to Princeville (40 minutes) → Punahele Road → Kapiolani Road to end.
• Parking: 8-10 street spots only. Arrive before 8 AM. Don’t block driveways.

Reading Ocean Conditions

ONLY visit when:

• Surf forecast shows 0-3 foot surf for North Shore
• NO swell period above 10 seconds
• Summer months (May-September) only
• Zero whitewater visible near rocks

Never visit October-April due to massive North Shore swells.

The Challenging Hike

10-15 minute descent through residential area. Steep, muddy, treacherous when wet. Rope sections often frayed. Razor-sharp lava rock near pool. Flip-flops inadequate—hiking shoes with ankle support mandatory.

Safer Kauai Alternatives

Better tide pool options:

• Tunnels Beach tide pools (summer, safer access)
• Lydgate Beach Park (protected children’s pools)
• Lawai Beach tide pools, Poipu (year-round calm)
• Salt Pond Beach Park, Hanapepe (naturally protected, warm)

What Visitors Say: Reviews split between perfect conditions vs. witnessing rescue helicopters. Many wish they’d received clearer danger warnings before hiking down.

6. Olivine Pools

• Location: West Maui, near Wailuku (Highway 30, after mile marker 40)
• Cost: Free
• Water Temperature: Cool ocean temperature with sun-warmed pockets
• Weather / Best Season: Summer (June-early September) when surf is calm; extremely dangerous in winter
• Review: 4.5/5 – Breathtakingly beautiful but high risk; multiple fatalities reported
• Official Website: N/A (natural formation, no official management)

Olivine Pools are spectacular natural tide pools formed by lava rock along West Maui’s rugged coastline. Named for the green olivine mineral deposits that give the water a turquoise tint, these pools sit at the ocean’s edge surrounded by hardened basalt. 

The 0.4-mile hike down steep, jagged lava rock requires good balance and sturdy footwear. While stunning for photography and swimming during calm conditions, these pools become deadly during high surf when waves sweep visitors into the ocean. Many fatalities have occurred here, making safety awareness absolutely critical.

7. Makapu’u Tide Pools

• Location: Kaiwi State Scenic Shoreline, East Oahu (accessible from Makapu’u Lighthouse Trail)
• Cost: Free (parking may fill quickly)
• Water Temperature: Cool ocean temperature, sun-warmed in shallow areas
• Weather / Best Season: Low tide during calm weather; summer months preferred
• Review: 4.6/5 – Crystal-clear water and excellent snorkeling, but challenging access
• Official Website: Hawaii State Parks – Kaiwi State Scenic Shoreline

Makapu’u Tide Pools are hidden gems accessible via steep rock scrambling from the popular Makapu’u Lighthouse Trail. These turquoise-blue pools nestle among volcanic cliffs, offering several meters of depth for swimming alongside shallow areas perfect for wading. 

The pools host diverse marine life including sea stars, crabs, and colorful fish. The 2.19-mile round-trip adventure includes a paved uphill section followed by challenging off-trail descent. Visit at low tide during calm conditions, as high surf makes the pools dangerous and inaccessible.

8. Wai Ola Springs (Private Retreat)

• Location: Opihikao, Kamaili Road, Puna District, Big Island (by reservation only)
• Cost: Contact for retreat and day-use rates
• Water Temperature: 108°F – 115°F (pure geothermal source)
• Weather / Best Season: Year-round (indoor facility)
• Review: 4.6/5 
• Official Website: https://www.waiolasprings.com/ 

Wai Ola Springs offers an exclusive geothermal soaking experience on a pristine 10-acre organic property. Fresh volcanic spring water emerges from the ground at ideal temperatures (108-115°F) and fills eight Japanese-style soaking tubs within an 822-square-foot bathhouse. 

Unlike public coastal pools, these tubs contain pure mineral-rich geothermal water with over 400 minerals—no ocean mixing. The property features fruit orchards, gardens, camping options, and hosts wellness retreats. Reservations required for day soaks, overnight stays, or group retreats.

9. Ahalanui Warm Pond (Historical – Now Destroyed)

• Location: Formerly at Pualaa County Park, Puna Coast, Big Island
• Cost: Was free before closure
• Water Temperature: Was 93°F – 95°F year-round
• Weather / Best Season: No longer accessible
• Review: Beloved by locals and tourists before 2018 eruption
• Official Website: Permanently closed

Ahalanui Warm Pond, affectionately called “Millionaires Pond,” was one of Hawaii’s most beloved thermal destinations before lava flows from the 2018 Kilauea eruption destroyed it completely. This man-made pool was fed by geothermal springs and protected from ocean waves by rock walls, creating a brackish swimming hole with perfect soaking temperatures. 

The site offered picnic facilities, showers, and bathrooms in a beautiful oceanfront setting. While Ahalanui is gone forever, its memory highlights how Hawaii’s volcanic landscape continually creates and destroys natural wonders.

10. Kapoho Tide Pools (Historical – Now Destroyed)

• Location: Formerly at Wai’ōpae Tide Pools Marine Life Conservation District, Kapoho Bay, Big Island
• Cost: Was free before closure
• Water Temperature: Varied with geothermal seepage
• Weather / Best Season: No longer accessible
• Official Website: Permanently closed

The Kapoho Tide Pools were a snorkeler’s paradise—a series of natural pools surrounded by coral reefs and heated by geothermal water seeping through lava rock. Located 1.5 miles north of Ahalanui, these pools hosted incredible marine biodiversity including sea stars, sponges, anemones, and tropical fish. 

The 2018 Kilauea eruption buried this entire area under dozens of feet of lava, eliminating one of Hawaii’s most unique geothermal snorkeling sites. While devastating, this loss demonstrates the dynamic nature of Hawaii’s volcanic geography.

11. Champagne Pond (Historical – Likely Inaccessible)

• Location: Beach Lots residential area, Kapoho, Big Island
• Cost: Was free (private residential access)
• Water Temperature: 70°F – 100°F depending on seep activity and location
• Weather / Best Season: Status unclear post-2018 eruption

Champagne Pond was a unique coastal inlet where volcanic hot springs bubbled up through black sand, mixing with ocean water. The geothermal gas created a distinctive fizzing sound and sensation, giving the location its name. 

Sea turtles frequently visited the three coves within the 100-foot inlet. Located within a private residential community, access was limited even before the 2018 eruptions. The current status remains unclear, though most geothermal features in this area were destroyed or significantly altered by lava flows.
