Mazatec Psilocybin Truffle Retreat - Netherlands
With Agder Iztacmitl (White Arrow), Eva Evers and Liz Lilley
May 21 - 24, 2026
THE LOCATION
WHAT TO EXPECT
We take a holistic approach to optimal wellbeing and spiritual development designed to deepen your experience and offer extensive preparation and integration support before and after focused on lasting results. During the retreat, we use several modalities to enhance your experience, such as breath work, meditation and sharing circles. To help you feel at your optimal best organic and locally sourced (where possible) meals are included during your stay with us.

Each participant will be assessed before entering the program through a compulsory application form and screening. Due to the powerful nature of psychedelic ceremonies and the impact that others sharing the space can have, we limit this retreat to 15 selected people.
