Four Seasons Resort Maui at Wailea has opened Kai Holo Spa, an island-inspired wellness centre built around contrast bathing, Hawaiian ingredients and personalised longevity services.
The 383-room oceanfront resort formally introduced the spa on July 23 as the centrepiece of a multimillion-dollar property transformation. Its website lists the Spa & Wellness Centre as having opened on July 1, with access available to resort guests and day visitors.
Meaning “flowing tide” in Hawaiian, Kai Holo combines a co-ed aquathermal circuit with a new Pacific Journeys treatment collection. A redesigned Next|Health longevity centre and expanded fitness facilities sit alongside the spa.
“Wellness today is deeply personal, and at Kai Holo that means meeting each guest exactly where they are,” Senior Spa Director Pat Makozak said in the opening announcement.

The aquathermal circuit follows Maui’s water cycle
Kai Holo’s centrepiece is a shared aquathermal area inspired by water moving from Maui’s mountains towards the Pacific. Black granite, cascading water and softly illuminated walkways evoke the island’s volcanic terrain.
Guests move between a vitality pool, therapeutic hot pool, cold plunge and steam room. The broader sequence includes a traditional sauna, infrared sauna, sanarium, multisensory shower and quiet relaxation areas.
Heat and cold are arranged as part of a sequence through the water and thermal facilities. The official spa programme suggests moving through warm pools, steam, sauna and cold immersion before a cool-mist shower and personalised massage.
Lighting in the aquathermal centre, treatment rooms and relaxation lounge shifts through the visible colour spectrum. Four Seasons says this system is intended to complement circadian rhythms while adjusting the atmosphere for energy or rest.
The relaxation lounge introduces a more technology-led layer, with Mind-Sync zero-gravity chairs offering audio programmes. Infrared face masks, Theragun massage devices and jet-lag boots are also available, while massage tables have complimentary pulsed electromagnetic field mats incorporating infrared light.
Guests must be at least 18 to use the spa facilities, and bathing suits are required in the mixed-gender aquathermal area. Visitors aged 12 to 17 may book treatments with a waiver signed by a parent or guardian.

Pacific Journeys draws on Hawaiian ingredients
The Pacific Journeys menu connects the new facility to Maui through island-grown ingredients and treatments influenced by Hawaiian bodywork. Honey harvested at the resort, Hawaiʻi-grown spirulina, kukui nut oil and botanicals sourced elsewhere in the islands appear across the collection.
The Kai Holo Signature Oceanside Ritual opens with a foot soak of warm black sea salt, then moves into a sugar-and-honey polish. Next comes a flowing massage with warm kukui nut oil, finishing with focused work on the scalp and feet.
Guests can experience the ritual inside the spa or in the resort’s oceanfront massage hales. Built in traditional Hawaiian style without nails or screws, these open-air structures sit above Wailea Beach among naupaka hedges, with the sound of the ocean forming part of the treatment.
Piko Mālama Wahine, created as a women’s wellness ritual, uses a warm herbal poultice containing honey, lemon balm, chamomile and lavender. Kukui oil massage and an amla oil scalp ritual complete the treatment, which Four Seasons positions for periods of personal transition.
The Spirulina & Astaxanthin Ocean Detox Body Ritual starts with dry brushing, then moves into a warm wrap of seaweed and Hawaiʻi-grown spirulina. It ends with a lomi lomi massage featuring astaxanthin-infused oil.
Another treatment, the Queen’s Garden Fern Ritual, takes its inspiration from the resort garden planted in honour of Queen Liliʻuokalani. Fern oil from Kauai is used during a restorative massage, followed by a warm lava mask along the spine and feet, which are wrapped in ti leaves.
Beyond Pacific Journeys, the menu covers facials, therapeutic body care, mindfulness services and refinement rituals. The Bio-Hacking Ultimate Facial layers seven skincare technologies intended to lift, refine and renew the skin, according to the resort.
Next|Health expands longevity services
Next to Kai Holo, the redesigned Next|Health centre extends a Four Seasons collaboration that began in 2021. The facility offers biomarker testing, IV therapy, NAD+ treatments and vitamin infusions, with a hyperbaric chamber due to arrive later this summer.
The concept brings clinical-style testing into a resort setting, with services tailored around recovery, performance and longer-term wellbeing. Next|Health’s published testing options include a baseline panel covering more than 50 biomarkers, alongside genetic, micronutrient, gut and food-sensitivity testing.
Guests can combine Next|Health services with the spa’s place-based rituals during one visit. The Next|Health centre is open daily from 9am to 5pm at the Wailea resort.
Fitness spaces open to the tropical air
The resort has also upgraded its fitness centre with sandstone-coloured Technogym equipment, separate cardio and weights areas, body-composition analysis and a stretching deck. Custom doors can open the gym to Maui’s tropical air when weather permits.
A new infrared Movement Studio hosts yoga and Pilates reformer sessions, while outdoor TRX classes make use of the wider resort setting. AI-powered coaching can also be connected to a personalised wellness assessment.
Meyer Davis handled the design of Kai Holo within a broader renovation reaching guest rooms, suites, and the Club Floor. Four Seasons says retreat programmes curated by Makozak will be added to the resort’s wellness schedule later in 2026.
