About the Advanced Psilocybin Retreat
This Advanced Retreat is designed for those who feel ready to go deeper beyond insight, into embodiment and integration.
It combines deeper ceremonial work, nature immersion, breathwork, and structured integration, designed to support meaningful change beyond the retreat itself.
What Makes the Advanced Retreat Different?
The Advanced Retreat builds on the foundation of our 3-Day Psilocybin Retreat with a more immersive programme for those ready to explore more deeply.
Alongside the guided psilocybin ceremony, the experience includes a sweat lodge and microdose ceremony, solo nature immersion, Psychedelic Breathwork and smaller tribe groups for personal reflection and integration.
Led by founder Niels van der Valk and an experienced facilitation team, the retreat combines full-group ceremony with smaller tribe groups for deeper reflection, integration, and support throughout the process.
