Yes. Belgians can book guided psilocybin truffle sessions with Triptherapie in the Netherlands, and many do so.
You can choose the Psychedelic Loft in Schiedam for individual or small-group sessions with an optional overnight, book a private on-location session at a rented place in the Netherlands near the border, or join a small open truffle ceremony.
If you prefer a quieter, more southern venue, The Bedding in Den Bosch is a convenient option, suitable for individuals or duos in a calm, private setting.
Most clients start with an intake so the team can check if a session is appropriate and advise on the best approach for your goals. For details and booking, see Triptherapie’s truffle session page.
Hope this helps, and you are welcome.
