Immersion: Synthesis’ 5-Day Legal Psilocybin Retreat in the Netherlands - February 2026

What if you could connect with the deepest parts of yourself, discover new insights, and step into a life of greater clarity, connection, and purpose?

At Synthesis, we warmly invite you to join Immersion—a comprehensive 7-week program that includes pre-retreat preparation, a 5-day psychedelic-supported retreat in the serene landscapes of the Netherlands, and post-retreat integration.

Designed for those who are eager to gain clarity and direction on their path forward, tune in to their deepest wisdom and truth, and unlock a greater sense of purpose and meaning in their life, we offer a safe space to intentionally explore the power of psilocybin truffles to catalyze lasting personal change and embody your most authentic self.

Since 2018, we’ve supported over 1,100 individuals through safe and legal psychedelic retreats. Using our integrative approach to transformative wellness, we combine leading-edge research with ancient wisdom traditions, rituals, and spiritual practices to curate a potent container that has the potential to catalyze lasting change and wellness.

“I did not really know what to expect, but what I received was beyond my wildest dreams. It was an exquisitely beautiful, profound experience. I am going to say: the most profound, exquisitely curated experience of my life.”

– Corina
