The Mayfly Immersive Experience

Sometimes we are our own worst enemies, creating barriers to growth. If you need are seeking assistance to get to the next phase of your journey then immersive experiences can help us do that.

Home: Welcome
MAYFLY retreats


Our immersive experience is an add-on to selected quarterly retreats, a psilocybin-assisted journey offers a safe, legal and supportive environment to experience a psychedelic journey, which can help you experience greater freedom, wholeness and creative flow. The psychedelic used at the retreats is the psilocybin-containing truffle and the retreats take place in the Netherlands where psilocybin truffles are legal.

Psychedelics can shift us out of our everyday perception and help open us up to a larger, mountain-top perspective from which new insights can arise.



Help us make better sense of the past, coming to terms with hardships we’ve faced and how past wounds might be influencing our current life.



Put us in touch with a deep well of inner resources with which we can begin addressing and transforming patterns we are stuck in.



For many, psychedelic journeys are also a first glimpse into ‘the Great Mystery’, and the spiritual dimension of life.

psychedelics alone are not enough


Our Approach

open and deepen

While psychedelics can open us to what is important in life, and steer our course, such experiences alone cannot keep us on track.


To deepen the insights gained during a psychedelic journey into a new way of life, we must address what is blocking us from experiencing our full freedom, wholeness and potential. We do so by attending to the various dimensions of our human experience: the relationship with ourselves, with others, with the natural world and with the mystery of life. 


This is the underlying principle woven into all our work and every one of our retreats.

set & setting

We take great care to optimise the two key factors determining a psychedelic journey: set and setting. Our retreats 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 Buddhism and the shamanic lineages of the Americas.

What’s included?

preparation support


Giving due energy to preparation before the psychedelic journey not only reduces the possibility of anxiety and tension blocking the flow of the experience, but it also enhances the probability of an enriched, deeper experience. Ahead of each retreat, you will receive reading material and suggested exercises to support your preparation for the retreat.


One week before the retreat you will also have the opportunity to meet your lead facilitator and fellow participants via video call, allowing you to get to know each other and feel safe in the group, as well as ask any burning questions you might have.


On the retreat itself, we offer one-on-one sessions with the facilitators, and individual and group activities to help you feel well prepared and supported, as well as safe and bonded with the group before stepping into the unknown.


integration support


In many ways, the journey only really begins when the psychedelic effect subsides.


In the days after the ceremony, we incorporate solo and group integration activities, and individual one-on-one sessions with the facilitators to give you the opportunity to explore the deeper nuances of your journey.


We also offer 3 weeks of support following the retreat – through group video calls as well as suggested exercises – to help you weave the insights from the retreat back into your everyday life.
