Mandarin Oriental, Costa Navarino opened its 2026 season on 31 March 2026 with a spa reorganised around a single question. The resort has 99 suites and earth-sheltered villas set into the hillside above Navarino Bay, at Pylos in Messenia. In February 2026 it had announced the season as a turn towards longevity. That meant a wellness programme built with practitioners from outside the resort, and a spa that starts with a measurement before any treatment.
A resort spa can add a longevity menu to its existing list of treatments in an afternoon. Building the season’s wellness programme around assessment, and handing parts of it to specialists who do not work for the resort, takes longer and is harder to reverse.
The first step is a measurement
The Wellbeing rooms start with two assessments. The first is a Mobility and Body Composition Analysis, an hour of tests that measure strength, endurance and flexibility. The second is a PNOE assessment, which the resort calls a breath analysis technology and a gateway to understanding the body’s own metabolic blueprint. It comes as a resting test, an active test or both. Each includes a virtual consultation, and the longest version adds a nutrition plan.
Both are readings. The figures come first, and whatever follows responds to them.
Practitioners from outside the resort
The visiting specialists are the second half of the plan. The main event of the season was Step into Self, a four-day retreat held from 7 to 11 May 2026. Taryn Toomey, founder of The Class, led it with Ally Bogard. It was a programme of movement, breath and stillness, and Costa Navarino named it first when it published the resort’s season.
The visits continue through the year. The osteopath Dr Ismael Mrani Alaoui, a Technogym global trainer, will hold personalised sessions on mobility and recovery at the resort from 22 to 29 August 2026.
Programmes that outlast the stay
Two of the season’s packages show what the approach is for. Revive & Recharge combines three mobility and body composition analyses with 12 one-to-one hours of personal training, yoga or Pilates, four Intelligent Movement Massages of 90 minutes each, and two Hydrafacials. Momentum Reset is leaner and more focused: the same three analyses, 12 one-to-one hours of personal training, and six sessions of compression therapy.
Both are valid for 6 months, and that says the most. A package used across half a year is built for a guest who comes back and is measured again against the figures from the first visit, more than for a single week in the Peloponnese.
Water, heat and the Asclepeia
Beneath the diagnostics, the spa is still a Mediterranean one. A 25-metre swimming pool runs from indoors to outdoors above the bay. The heat and water rooms have olive and herbal saunas with wide views, a cold plunge, experience showers, a hydrotherapy tub, Japanese foot baths and a mineral and flower steam bath. The fitness centre has an outdoor movement studio. Guests are asked to arrive 45 minutes before a treatment, which is roughly the time the sequence needs to be worthwhile. Treatments run from 10am to 8pm and the facilities from 9am to 9pm. The fitness centre is open 24 hours and staffed from 7am to 9pm. Nobody under 18 is admitted to either.
The treatment menu stays close to the ground it stands on. Reviving Asclepeia lasts 3 hours. It follows the healing sequence of the Asclepeia, the ancient healing sanctuaries, and the 4 Elements Philosophy of ancient Greek medicine. Signature Intuitive Time, at 2 hours 15 minutes, draws on kinesiology, the study of how the body moves, and is timed to the sunrise and sunset over Navarino Bay.
The wider estate
Costa Navarino’s own account of its 2026 season spreads wellbeing across the whole estate, beyond any one spa. It names Hippocratic philosophy and modern science, a Messinian Wellbeing Festival, Seasonal Wellbeing Weeks, sunrise movement and walks through the olive groves. The estate has three spas: Anazoe Spa, AWAY Spa and the Mandarin Oriental spa, which the estate’s own description credits with personalised holistic treatments.
What sets the Mandarin Oriental spa apart is the order of things. Elsewhere on the estate, the land itself is the source of wellbeing. Here the week begins with a breath test and a body composition reading, and the land is the setting for that work.
Who is this for
The spa suits a guest who wants clear figures and a training plan, as well as heat, water and rest. A curved stone and glass pavilion stands at the head of a long outdoor pool, with loungers along one side and the blue bay and low hills beyond. Indoors, the pool is glazed to the sea on one side and backed by a living wall of greenery. The relaxation room has rough stone walls, linen curtains and cream chaise loungers with small tea trays.
