Our OPEN retreats offer a safe and accessible entry point into psychedelic and other forms of inner exploration and personal growth.

They are designed to prepare you to let go into a receptive, trusting state of mind (set), in an environment in which you can feel completely safe and supported (setting). We include exercises and approaches from the Western clinical model, somatic and transpersonal psychology, as well as from ancient wisdom traditions across different cultures and times such as Tibetan Buddhism and the shamanic lineages of the Americas. Open retreats introduce you to the foundational pillars of our approach: relationship with self, relationship with others, relationship with nature, relationship with the Mystery.  

Who is it for?

Our OPEN retreats are for all sufficiently mentally and physically healthy individuals, regardless of prior experience with psychedelic substances. The retreat is for you if you are looking to discover yourself more deeply, expand into your potential, address blocks in your life and/or transform unwholesome patterns.


5-days / 4-nights

On our 5 day retreats, we dedicate an extra day for preparation. You have a whole day to arrive and feel safe, settled and connected to the place and the group. It allows more space to prepare internally, to come into deeper contact with what is blocking us in our lives, and distil our intention for the ceremony. The preparation day is then followed by the ceremony and integration day as with the 4-day retreat.

  • Costs

    • 2,450€ for a 5-day retreat including facilitation, food and accommodation
    • 45€ for the psychedelic truffles paid directly to the smart shop (not to us). The reason for this extra cost is that in order to sell truffles you have to be a registered ‘smart shop’, so for licensing reasons, we cannot give you the truffles directly and you have to purchase them yourself.
    • Optional: 100€ per night for a private room (standard shared rooms accommodate 2-3 people).


    After registration, you will receive an email with our bank details for transfer. We will hold your reservation for 3 business days to give your bank transfer time to arrive on our account. We are not currently able to accept credit cards or Paypal payments but we are working on expanding our payment options and hope to be able to offer you these options soon.

    • Our retreats are for people in good mental and physical health. We do not offer therapeutic or medical treatment.
    • Even though the vast majority of our participants have very meaningful and beneficial experiences, there is no guaranteed outcome from participating on a retreat.
    • The majority of research indicating the positive effects of psilocybin was done in a clinical setting, which is very different to that of a retreat environment. More research is needed to explore the benefits offered by the psilocybin experience.
