A controlled immersion into the ocean, into breath, and into your nervous system.

The Method

Master Your State Before You Enter the Water

Over the course of this retreat in La Ventana, Baja California, every guest will go through my full Poseidon Breath method — the same framework I use for elite freediving preparation, performance under pressure, and mental resilience.

This is the foundation of the experience. Before we enter the water, you will learn to master your state. You will understand how your nervous system works. You will learn how to downregulate on command. You will experience how breath changes perception, stress tolerance, and clarity.

Structured & Progressive

The Poseidon Breath Sessions

• How to balance oxygen and CO₂ tolerance
• How to shift from sympathetic to parasympathetic dominance
• How to increase focus before performance
• How to control anxiety responses in high-stress environments
• How breath retention reveals your mental patterns
• How to extend your relaxation phase under pressure

You leave with tools that extend far beyond freediving.
This is nervous system training for life.

After the Dive

Out of the Water, the Retreat Becomes Community

Evenings are held on the beach. We host curated beach dinners under open skies. Fire, salt air, long tables, deliberate conversation.

We also host beach movie nights — projecting cinematic underwater footage and inspirational films directly onto the sand. Barefoot. Ocean in the background. Storytelling under the stars.

This is intentional decompression.

Your Host

Tavi Castro

Tavi Castro is a world-class freediver, performance coach, and the founder of Poseidon Ascend. Born in Guadalajara, Mexico and raised in Canada, he holds a degree in Aerospace Engineering from TU Delft — and brings that same analytical precision to breathwork, nervous system regulation, and human performance.

With breath holds exceeding 7.5 minutes, dives to depths of 90 meters on a single breath, and three world records to his name, Tavi has earned the title “The Real Aquaman” — a reputation that led to his involvement in the global promotional campaign for Aquaman and the Lost Kingdom.

But this retreat is not about spectacle. It is the product of years spent studying how breath, pressure, and stillness reshape the nervous system. Tavi has coached elite athletes, founders, and high-performing individuals through the same protocols you will experience in Baja — structured, measurable, and grounded in physiology.

He is also a dedicated ocean conservationist, collaborating with Sea Shepherd and using his platform to advocate for marine protection. Every expedition in this retreat reflects that commitment — responsible, intentional, and deeply connected to the environment.

“Every dive is a journey inward — beyond physical limits and into a deeper connection with nature.”

Movement & Longevity

Yanita Brings Another Dimension to the Experience

Her background in elite fitness and discipline elevates the retreat beyond technique. She guides functional movement sessions designed to improve mobility, posture, and breath mechanics — essential for diving and equally important for longevity.

Together, we focus on:

• Physical strength with efficiency
• Body composition awareness
• Nervous system recovery
• Sustainable performance
• Discipline without burnout

This is not an escape from life.
It is an upgrade to how you operate within it.
