Surrenne launches four-night longevity retreats with cold plunge focus

Surrenne unveiled a four-night longevity retreat at The Maybourne Riviera that places cold-water immersion and the hotel’s thermal circuit at the heart of a curated wellness protocol. The program, delivered in a three-phase model called Ground, Recharge, Regenerate, mixes breathwork, movement, nutrition and practitioner-led treatments to target circulation, recovery and nervous-system regulation.

The Recharge phase highlights cold immersion as a core practice. Retreators moved through the thermal circuit’s cold plunge pool alongside guided sea swims, coastal walks and supervised cold-water sessions designed to pair contrast therapy with breathwork and movement. Organizers presented cold exposure as a tool within an integrated protocol for vagal tone and recovery, not as a stand-alone trend.

Program structure is modular and includes sample offerings such as the Anti-Inflammatory Reset and a Spring Equinox Retreat. Each four-night cycle begins with grounding practices to lower baseline arousal, shifts into the Recharge phase for contrast and stimulation, then settles into Regenerate modules that emphasize nourishment and practitioner treatments. Nutrition plans and practitioner-led therapies are built into the daily schedule to support the physiological effects of cold exposure and movement work.

Retreat pricing was listed from around EUR 4,500 for full-board program participation; accommodation is charged separately. Booking notes emphasize that room rates are additional and should be confirmed when reserving a program package. The retreat is pitched at those seeking a structured longevity experience—seasoned cold plungers who want a science-led context and newcomers who prefer guided progression and on-site supervision.

For regular cold-bathers and community members who track modality trends, this offering reinforces a shift away from single-technique marketing toward bundled, multidisciplinary programs. Practical value for participants includes supervised entry into cold exposure, a scripted progression through breath and movement practices that reduce cold shock risk, and access to clinicians and therapists who can adapt sessions to recovery goals.

Verify medical suitability with a physician before booking, confirm what the full-board fee covers, and check room-rate policies at time of reservation. Expect retreats like this to influence other coastal spas to formalize cold-water protocols, and watch for more seasonal modules and varied lengths as operators respond to demand.
