Beckley Retreats — Netherlands

Beckley Retreats runs a structured, multi-week program built around a 5–6 day in-person retreat at De Hoorneboeg Retreat Center, roughly 40km from Amsterdam. The in-person retreat sits inside an eleven-week arc: around four weeks of virtual preparation, the retreat itself with two guided psilocybin-truffle ceremonies, and roughly six weeks of virtual integration support afterwards.

Truffles (as distinct from mushrooms) are legally sold and consumed by adults in the Netherlands, and Beckley’s own materials cite this distinction explicitly. The program states a group size of around 15 participants with a facilitator ratio of roughly 1:3, and describes a multidisciplinary facilitation team including a physician and a trauma-informed psychotherapist.

Published pricing is roughly USD $6,750–$9,500 (approx. A$9,417–A$13,253*) depending on room type.
