Yes. In the Netherlands it is generally straightforward to book a guided psilocybin truffle session for adults, since truffles are legal and many facilitators offer structured services.
Most providers use an online intake to check for contraindications like certain medications or serious conditions. If you are cleared, you will have a short preparation call 1 to 2 weeks before the date and then confirm with payment. With some planning, you can usually find a slot within a few weeks.
Plan your trip around the session: arrive the day before to rest, have your session day, then keep a recovery or integration day before flying out. Sessions can be hosted in dedicated spaces or at your accommodation, depending on the provider.
