Apprenticeship Retreat Immersion Training is an 8-day experiential program held at New Eden in the Netherlands. It uses a non-directive, clinically informed, and somatically intelligent approach to psychedelic training and facilitation. The curriculum covers facilitation fundamentals, dosing and consent, touch preference conversations, integration techniques, flight instructions, and group-sharing circles. Participants join as Active Witnesses, observing and supporting retreat and ceremony processes, assisting with setup, and taking part in debriefs and facilitator Q&A sessions. The retreat includes three psilocybin-containing ceremonies, with opportunities to support peers, have a personal journey, and journey together with fellow participants. It is designed for students and graduates of the Psychedelic Practitioner Core Training who want practical experience in holding space and refining group facilitation skills.
