The Stars Frequencies Truffle Retreat is a two-day truffle retreat in the Netherlands on 17 and 18 October 2026 in the Elsterdome in Elst (Gelderland), with a truffle ceremony and sound healing guided by Rosa, and breathwork and yoga with Kim. You stay one night on location, with organic dinner and breakfast included. The retreat costs €495, or €395 as early bird until Saturday 10 October 2026, for a mixed group of up to 12 participants. The last day to sign up is 15 October 2026.
Land first, then the journey.
The retreat runs over one weekend: Saturday 17 and Sunday 18 October 2026. It takes place in the Elsterdome in Elst, Gelderland, a round dome among the fields. The group is mixed: men and women. You arrive on Saturday afternoon, the truffle ceremony starts that evening, you sleep on location, and on Sunday you come back gently before closing at noon.
Accommodation is part of the retreat. You sleep one night in the dome with the group: bring your own pillow and blanket. All food is organic and vegetarian, with dinner around 23:00 after the ceremony and breakfast the next morning. Parking at the Elsterdome is free, and if you come by train you can arrange with Rosa to be picked up at Elst station.
Some people find this page while searching for a psilocybin retreat in the Netherlands, or a psychedelic retreat near Amsterdam. This retreat works with truffles, which are legal in the Netherlands and not listed in the Opium Act. It isn't a festival and it isn't a performance. It's two quiet days, a small group and a clear structure.
The last day to sign up is 15 October 2026.
Many of the people who come to Rosa know themselves well. They understand their patterns, they've read the books, they can explain exactly why they feel stuck. What they miss is feeling it. And the idea of letting go can be the scariest part, because letting go sounds like losing control.
The retreat is built for that. Letting go is not a requirement. It is a result. So the first afternoon asks nothing of you. You arrive, rest and take in the surroundings. Then there is a sharing circle and 30 minutes of breathwork with Kim. Only after that, at five in the evening, does the truffle ceremony begin. Your body has had a few hours to settle before anything else happens.

| 14:00 | Arrival: rest, land and take in the surroundings |
| 15:30 | Sharing and breathwork (30 min) |
| 17:00 | Truffle ceremony with Rosa and Kim begins, about five hours |
| ± 22:00 | End of the ceremony, coming back gently in the dome |
| ± 23:00 | Organic, vegetarian dinner |
| After | Sleep in the dome |
| Time | Day 2 (Sunday) |

The morning after matters as much as the evening. Instead of going straight home, you wake up in the same place, do breathwork and yoga with Kim, rest in the sound healing with Rosa, share what you want to share and eat breakfast together. That gives you time to come back at your own pace.
Before the retreat you also get an intake form and a short phone call with Rosa. That call is where you talk about your health, your medication and whatever feels daunting, and where you decide together whether the retreat suits you right now.
This truffle retreat costs €495 per person. If you sign up as early bird, until Saturday 10 October 2026, it costs €395. That price covers both days: the truffle ceremony and sound healing with Rosa, breathwork and yoga with Kim, the sharing circles, one night on location, and organic dinner and breakfast.
Prices for retreats vary a lot, and we'd rather not compare with numbers we can't check. What we can tell you is how this retreat relates to a single day with Rosa: a group truffle ceremony in Amsterdam costs €295 per person for a day of about 7 hours, without an overnight stay. You'll find all day prices on the prices page.
You pay nothing when you sign up. Rosa first sends you an intake form and you plan a short call. Only once it's clear the retreat is right for you do you arrange payment.
Rosa is a ceremony facilitator and sound healer, and the founder of Stars Frequencies. She guides the truffle ceremony, together with Kim, and the sound healing on Sunday, and watches over the safety and calm of the group, from the intake to the closing. She is in the room for the whole ceremony. If someone panics, Rosa handles it with care and knows how to help that person calm down. A gentle touch only happens with your permission.
Kim guides the breathwork and yoga sessions and assists Rosa during the truffle ceremony, so she is there the whole evening. For her, breath and movement are the way into more space in body and mind, without having to think your way there.
“In the end I took the step anyway, because I finally wanted to feel something again instead of just thinking. I had been in my head for so long that I no longer knew what was underneath.”
This retreat is new, so these words come from someone who joined one of Rosa's truffle ceremonies before. More stories are on the experiences page.
The retreat suits you if you want to take your time: an afternoon to arrive, a ceremony in the evening and a morning to come back gently. It suits you if you live a lot in your head and want room to feel again, without it having to happen on command. And whether or not it's your first time, it suits you if you'd rather do this in a small group than alone.
It isn't for you if you're looking for a party experience, or for treatment of a mental health condition; a doctor or therapist is the right place for that. It also isn't for you if one of the contraindications applies, such as psychosis or schizophrenia in yourself or a first-degree family member, bipolar type I, dissociation, lithium or MAO inhibitors, or pregnancy. The full list is on the safety page.

Visiting from abroad, or not fully at home in Dutch? The English FAQ about the truffle ceremony answers the common questions about what's legal and how a guided ceremony works.
Rosa guides in Dutch or English. Mention it when you sign up on WhatsApp, so she can take it into account.
It can be. About half of the participants are doing it for the first time. No experience needed. You start with an intake and a short call with Rosa, so you know what to expect and can see together whether the retreat is right for you.
No, many people come alone. The group is mixed and small, up to 12 participants, and there is a sharing circle on both days. Rosa is in the room for the whole ceremony and looks out for everyone.
That's allowed, and many people feel nervous beforehand. During the ceremony Rosa is in the room the whole time, and you can always ask her for support. Whatever feels daunting, you discuss beforehand in the intake.
You discuss that in the intake with Rosa. Mention all medication you take, and together you look at whether taking part is wise for you. With some medication a ceremony isn't possible. If in doubt, also check with your GP. A ceremony is not a replacement for medical or psychological care.
Bring loose clothing in layers you can sit and lie in comfortably, your toiletries, and your own pillow and blanket: you sleep in the dome. You're welcome to bring your own sleep mask, and there are also some ready for you. After signing up you receive a guide with everything about the preparation.
You don't pay anything when you sign up. Rosa then sends you an intake form and you plan a short call together. Only once the retreat is right for you do you arrange payment. The early bird price of €395 applies until Saturday 10 October 2026, after that the price is €495. The last day to sign up is 15 October 2026.
The ceremony starts at 17:00 and lasts about five hours. Around 23:00 you eat an organic, vegetarian dinner together. After that you sleep in the dome. Day two starts at 08:00 and the retreat closes at 12:00.
Up to 14 days before the retreat you can move to another date free of charge, or get a refund, possibly minus administration costs. Between 14 and 7 days before, you get 50% back, or you move the full amount once to a new date. Within 7 days, or if you don't show up, there is no refund. If you can't take part safely for medical or psychological reasons, or Rosa decides after the intake that taking part isn't wise, you get a fair solution such as a refund or a credit.
Yes. Truffles (sclerotia) are legal in the Netherlands and are not listed in the Opium Act. Mushrooms are banned. Stars Frequencies only works with legal truffles.
Send Rosa a message on WhatsApp. She sends you an intake form and you plan a short call. You pay nothing when you sign up.
