Group ceremony in the Netherlands
Guided psilocybin ceremony near Amsterdam
A full day with legal psilocybin truffles, a maximum of ten participants and two facilitators at our location in Vijfhuizen.
A psilocybin ceremony is more than taking truffles. The setting, screening, people around you and the way the day closes all shape the experience.
Mental Health Temple has guided psilocybin ceremonies since 2018. Approximately 1,500 participants have taken part under guidance. We use legal psilocybin truffles, also known as sclerotia.
This is not a medical treatment and MHT is not a research institution. We do not promise relief from symptoms or a specific personal result. The intake helps us assess whether the ceremony appears appropriate, but it cannot remove all risk.
The day
From intake to dinner
You receive practical details before arrival. This is the overall structure you can expect.
- 1
Telephone intake
Before the ceremony, we discuss your health, medication, reasons for joining and whether participation appears suitable.
- 2
Arrival and preparation
You meet the group and facilitators, hear how the day will unfold and take time to settle before anything begins.
- 3
The experience
The effects generally last four to six hours. Most participants lie down with an eye mask while music supports the setting.
- 4
Coming back
As the effects subside, there is time to move, drink and eat something small. Nobody is rushed out of the experience.
- 5
Reflection and dinner
The group reflects on the day and shares a prepared dinner before leaving the location.

When it becomes difficult
A difficult experience is possible
MHT uses “bad trip” as a broad term for a difficult experience that may involve fear, panic, grief or confusion. A difficult emotion is not automatically something that must be stopped. Facilitators first allow space for your process while observing whether you can move through it yourself.
If you remain stuck in a repetitive thought or emotional loop, a facilitator may use questions and other guidance techniques to help bring movement back into the experience. Even with preparation and guidance, an unpleasant experience or symptoms afterwards cannot be ruled out.
Read all safety and eligibility information before applyingNew to this? Start with what magic truffles are, or see what a ceremony costs. Searching from the city? See magic mushrooms in Amsterdam. Travelling here from another country? Read this first. And if you came looking for psilocybin therapy rather than a ceremony, the difference is set out under psychedelic therapy in the Netherlands.
Our approach
How the day is set up
We arrange our ceremonies on the basis of the safety guidelines developed at Johns Hopkins University for research with psychedelics. In practice that means four things.
- Screening and preparation beforehand. Both by telephone. We look at whether participation is sensible in your situation and go through what to expect.
- Set, setting and dose. The state you begin in, the room you lie in and the amount you receive. Together these shape how a day unfolds.
- Facilitators who stay present. Someone is in the room with you throughout the session. For a group of up to ten participants, that is two facilitators.
- Reflection and integration. A reflection on the day itself, and a follow-up phone call about three weeks later. That call is where integration happens.
We are not a research institution and do not conduct studies. We use those guidelines as a safety framework, not as a certification. We do not provide medical treatment, and a ceremony does not replace regular care.
Frequently asked questions
What is a psilocybin ceremony?
It is a guided session in which legal psilocybin truffles are taken in a prepared setting. At MHT, the wider process includes a telephone intake, preparation, guidance during the experience, reflection afterwards and dinner before departure.
How many people are in a group?
A group has no more than ten participants and is guided by two facilitators throughout the day.
How long does the experience last?
The effects generally last four to six hours. Including arrival, preparation, reflection and dinner, you spend a full day at the location.
How much does a group ceremony cost?
The current group ceremony price is €299 per participant. Guidance, drinks, snacks and dinner are included.
Is a positive outcome guaranteed?
No. A ceremony may be meaningful, difficult, neutral or disappointing. Preparation and guidance do not guarantee a particular experience or outcome.
What happens after the ceremony?
The day ends with a reflection and a shared meal. About three weeks later we call you for a follow-up conversation. If you would like contact sooner, you are welcome to call us; you do not have to wait for those three weeks. If you want to continue working with what came up, an individual session is possible. That falls outside the ceremony price.
Is it comparable to MDMA or ecstasy?
No. The effects differ and so does the setting. Our day is arranged for going inward and processing, not for a night out. Joy and lightness do come up for many participants, but that is not the starting point.
Do I need to have symptoms to take part?
No. Most people who come to us are stuck somewhere: in grief, worry, fear, or in patterns they want to leave behind. You are equally welcome without symptoms. Curiosity about self-reflection or a renewed connection with yourself is reason enough. Whether participation is safe in your situation is what the intake is for.
Some ceremonies have a theme. What does that mean?
A themed ceremony, such as relationship dynamics, goes deeper into one subject for the whole day. You are in a group with people who came for the same theme, and the music is matched to it. Relationship dynamics can concern a romantic relationship as much as family; patterns from one often reappear in smaller form with other people.
What participants say afterwards

My second inner journey really gave me something. Where I would normally put up a wall, being introverted and used to keeping my feelings in, the ceremony gave me room to open those shutters. I came back to my core, as it were: I know who I am again. Empathetic, calm, and willing to actually show that to my girlfriend, my children and the people around me. The guidance, the music and the ritual setting made me feel safe enough to turn inward. What has stayed with me most is that the insights did not come from outside but from myself, which means I can carry them into daily life. That is exactly what makes it valuable: it does not stop when the ceremony stops. I am grateful for this experience and for the work that starts now. I would recommend it to anyone willing to look at themselves honestly.

Last weekend I did the Psi ceremony with Kelly and Sandra. A warm welcome, a pleasant room, clear explanations. I went in open and without expectations, and before long the truffles began to work and my inner journey started. It was not frightening; it brought me so many insights. I was able to let things go and there was relief, a kind of liberation. To me it feels like a new beginning. I am leaving things behind and looking at the future with confidence.

My first psilocybin ceremony. I found it really nerve-racking, but I went in without expectations. And it was truly wonderful. So much processed in a single day. Dora and Sandra were also so very kind to everyone. So much love and warmth from the moment you walk into the calm setting of the building. And a lovely meal to finish. I can genuinely recommend it to anyone and I will certainly go again. Thank you Dora and Sandra for this remarkable journey.

I did the Holy Ceremony in February, after several Psi Days and EMDR over the past years. Where my personal growth had been noticeable and my backpack had grown lighter, this ceremony needed to land. In fertile ground, I now dare to say. That last piece I could not quite reach, or did not quite dare to go to, finally arrived, with all the loving support I could have wished for. Coming home in myself. I cannot describe it any other way. Now, almost eight months later, I have got to know myself again. My real core. Before life came over it. I can only encourage and recommend that everyone give this to themselves. Being happy sounds so much easier than it is, but if you dare to take the leap it is worth every second. I am grateful for Dora's guidance, which leaves you able to put the pieces of the puzzle in the right place yourself afterwards.

I have been coming to Dora for a while now and have worked very hard on myself over the past years. Thanks to her loving guidance and support I have been able to take enormous steps in my personal growth. I am extremely grateful for that. The Psi Day was once again a beautiful and remarkable experience. It helped me dive deeper into myself and discover new insights. The safe and warm environment that Dora and the team create meant I felt completely at ease. I am hugely grateful for this transforming experience and for Dora's support. For anyone looking for inner growth and connection, I can genuinely recommend this.

Last Saturday I was able to take part in the Holy Ceremony. What a beautiful day it was. A very special experience, and extra special to go through it together with my son. The week before I did the Psi Ceremony, also very special because I was there with my daughter. At first I found it all quite nerve-racking, but the atmosphere at Dora's is so warm. I am extremely glad I got to experience all of this. Dora, Zoë and Sandra, thank you so much for two beautiful days.
