Lanzarato-Canary Islands
May 9 - 11, 2025
Elke Maria Osterburg
Most of us are running on empty and calling it normal.
Stress itself was never the enemy, it’s what gets you through a deadline, a hard conversation, a real challenge. The problem is losing the capacity to come back down afterward: to actually switch off, recover, and return to yourself.
Whether it’s back-to-back deadlines or a life that never switches off, that lost capacity has a way of becoming invisible. We stop noticing it. We just stop sleeping well, stop thinking clearly, stop feeling like ourselves.
This retreat is built around one honest idea: your body already knows how to rest. It just needs the right conditions and the right frequency, to remember how.
Binaural beats. Natural sounds. 3D womb sounds. Non-linear, evolving music. Precise entrainment into Delta, Theta, and Alpha brainwave states. The Earth’s own Schumann Resonance. Together, these form the sound experience at the heart of this retreat.
On Day 2, you undergo your Bio-Tuning® session — a real-time HRV measurement that identifies your unique Individual Fundamental Frequency, as distinct as a fingerprint. This becomes the foundation for your personalized Brainwave Entrainment® experience throughout the retreat.
Each afternoon and night, you’ll listen to sessions built on your own frequency to support deeper rest, calm, focus, and mental clarity. After the retreat, you’ll receive 7 personalized Brainwave Entrainment® tracks to keep for daily practice at home.
Bio-Tuning® and Brainwave Entrainment® are complementary wellbeing practices for relaxation and are not a substitute for medical diagnosis or treatment. They cannot be offered during pregnancy, with a history of epilepsy or seizures, or with implanted medical devices such as pacemakers.
Developed over 40+ years by Dr. Jeffrey Thompson, D.C., Bio-Tuning® is a personalized sound relaxation method designed to help regulate the nervous system and support deep calm and rebalancing.
Feldenkrais® complements this work through the body. Its founder, Moshé Feldenkrais, a nuclear physicist and engineer with a black belt in judo, developed the method in the 1940s after a severe knee injury, discovering that gentle, unusual movement could retrain the brain’s own patterns. Long before neuroscience had the word for it, he was working with what we now call brain plasticity.
Most of us move the same way, every day, for decades, patterns so habitual we’ve stopped questioning whether they’re serving us. Feldenkrais® offers something different: slow, exploratory movements, the kind babies do naturally before movement becomes automatic. Many people find this gentle novelty invites the nervous system to soften and settle, alongside the sound work at the heart of the retreat.
It’s offered on the beach each day at sea, entirely optional, a complement to the main journey, not a requirement of it.

Maximum 6 Guests: This intimate retreat is limited to just six guests, ensuring a deeply personal experience and individual attention throughout your journey. Only six places are available—once they're filled, bookings will close.
Accommodation: Accommodation is included in your retreat investment. During the retreat, you'll stay both in comfortable campsite accommodation and aboard our sailing boat. Berths are allocated according to your booking and group arrangements, as described in the Where You'll Sleep section.
Your week moves between two worlds:
At Calacavallo (Days 1, 2, and 6): Comfortable holiday huts accomodation — couples share a hut together, and solo travelers are paired to share, so everyone has a real bed and a proper roof over their head.
Aboard (Days 3–6): A private double cabin, two cozy one-and-a-half-width berths (perfect for couples who don’t mind sleeping close, or a solo traveler who’d like extra room), and one single berth — comfortably accommodating all 6 guests. Our crew usually sleeps on deck, keeping watch under the stars — though if you’d like to trade places for a night, we’re happy to arrange it. Falling asleep on deck under a sky full of stars is, for many guests, one of the most memorable nights of the week.
Exact berth and hut assignment is confirmed at booking based on your group's makeup — let us know if you're traveling solo, as a couple, or with a mix.
A Note on Weather & Comfort
Sardinia's summer waters are generally calm and welcoming, but the sea sets its own schedule. If weather conditions aren't suitable for sailing, we simply shift the days at Calacavallo campsite — still swimming, still sessions on the beach, still the same warmth and community, just with your feet on solid ground.
And if seasickness ever gets the better of you during the sailing days, you're always welcome to a comfortable bed back at the huts rather than staying aboard.
Either way, your week is never at the mercy of the sea.
Meet Elke Maria Osterburg
Over 25 years of experience in Bio-Tuning®, Brainwave Entrainment®, and Feldenkrais®
The heart of every retreat is its guide. Elke creates an intimate space where guests reconnect with themselves through movement, sound, and nature.
I help people step away from busy urban lives and back into connection with themselves and the world.
For over 25 years, I've used movement and sound to help guests clear life's noise and rediscover stillness, clarity, and belonging.
I believe in staying present and grounding in nature to transform the ordinary into extraordinary healing experiences.
Guests often find our time together deeply transformative—a gentle invitation into a fuller version of themselves.
Guidance. Growth. Grounding.
I would be honored to guide your journey to the sea, the sound, and the stillness.

Meet Your Skippers
While Elke guides your journey of sound, movement, and restoration, you'll also be looked after by an experienced sailing crew who ensure every moment at sea is safe, comfortable, and unforgettable.
Riccardo and Linda, your expert skippers, take care of everything on board — from freshly-cooked local food to sunset aperitivi.
Who Is This For?

Come home with more than a tan. Your personalized frequency becomes a tool you can use every night, long after the boat docks.
Six guests, one boat, one unforgettable week.
A week of sailing, sound, movement, meaningful connection, and personalized tools to support your wellbeing long after you return home.
