ICPR 2026 & a Psychedelic Retreat: Where Science Meets Ritual, Art and Nature

By Nature Temple Teuge — Updated Nov 10

The Interdisciplinary Conference on Psychedelic Research (ICPR 2026) is one of the world’s leading gatherings on psychedelic science. While researchers and clinicians present cutting-edge findings, our centre , Earth Awareness & the Nature Temple in Teuge, offers something complementary: a place where ritual, nature and art shape real-life psychedelic experiences.

Visitors of ICPR 2026 have the unique opportunity to extend their conference trip with a 3-day psilocybin truffle retreat in the Nature Temple: an environment designed for inner exploration, integration and creative transformation.

We provide exactly the kind of setting in which the non-clinical, experiential side can truly be lived, in connection with nature, ritual and art.

What is ICPR 2026?

ICPR (Interdisciplinary Conference on Psychedelic Research) is organised by the OPEN Foundation in the Netherlands. It is held every two years and brings together researchers, therapists, policymakers and practitioners. The next edition takes place in June 4/6 2026.

The conference focuses on clinical science, social impact and psychedelic-assisted therapy. It has become a central meeting point for professionals shaping the future of psychedelic research.

The role of Earth Awareness retreat centre

Since 2008, Earth Awareness has been one of the pioneering psychedelic retreat centres in the Netherlands. Over the past 18 years, thousands of participants from around the world have taken part in our psilocybin truffle retreats.

Our mission is to create a safe, artistic and nature-connected environment in which people can explore altered states of consciousness with care, integrity and expert guidance.

What sets us apart:

✔ Experience

Our team has facilitated an exceptionally high number of ceremonies, giving us practical knowledge that few centres can match.

✔ Setting

The environment is one of the most influential factors in a psychedelic experience. The Nature Temple — surrounded by forest, fire, organic structures and art — offers an atmosphere unlike any average retreat centre. Many participants describe it as stepping into “another realm” the moment they enter.

✔ Music & Guidance

Live music, ritual elements and our warm, experienced team create the conditions for a deeply meaningful and beneficial journey.

A Bridge Between ICPR and Personal Experience

ICPR is rich in scientific insights, research findings and intellectual inspiration. Our retreats offer the complementary dimension: ritual, art, nature, embodiment and integration.

Where ICPR provides knowledge, we offer the space for that knowledge to land in personal experience.

Opportunities Around ICPR 2026

We envision several forms of collaboration for conference participants:

• Attend a retreat before or after ICPR

• Combine scientific learning with experiential understanding

• Explore joint projects with therapists, researchers or facilitators

  
  

Visitors can extend their trip with time for rest, reflection and integration in the peaceful environment of the Nature Temple.

3-Day Psilocybin Truffle Retreat: June 12–14, 2026

Right after the ICPR conference, we will host a 3-day psilocybin truffle retreat, offering an ideal space to deepen or integrate the insights gained during the conference.

The retreat includes:

• Preparation workshops

• A live-music psilocybin truffle ceremony

• Healthy, mostly home-grown food

• Integration sessions & aftercare

• Clear safety guidelines and intake procedure

  
  

This retreat is designed for participants who want a safe, inspirational and supervised setting to explore higher consciousness. Note that the ticket sales are on and space is limited.

Intake form June 12/14 2026

ICPR provides knowledge; we offer the space to let that knowledge land in personal experience.

The future of psychedelic research and retreats

As scientific interest in psychedelics continues to grow, it becomes increasingly important to integrate science with human aspects: ritual, creativity, nature connection and community.

We believe the future lies in combining evidence-based understanding with embodied experience.

FAQ

What can I expect from the effects of magic mushrooms?

On an empty stomach, psilocybin truffles generally take effect within 30 minutes. The body may feel restless at first, which often fades as you relax into the experience. The journey usually lasts 4–6 hours and comes in waves. Some people feel mild nausea, which can be eased through breathwork, movement or relaxation.

Experiences can include visions, emotions, insights and shifts in perspective. The journey may move between clarity, emotional release and profound bliss. Our team supports participants before, during and after the ceremony.

Why do people attend a magic mushroom retreat?

People join retreats to:

• Heal past experiences

• Reduce anxiety or emotional burdens

• Gain clarity, insight or vision

• Reconnect with creativity and inner guidance

• Improve self-care and relationships

• Feel supported in an honest, open community

• Mark important transitions or life moments

  
  

Do you use truffles or mushrooms?

We use psilocybin truffles, which are legal in the Netherlands. Truffles contain the same active compounds as the mushroom fruiting bodies. We use the term “mushrooms” in our texts because visitors outside the Netherlands are more familiar with that term.

How do magic mushrooms compare to ayahuasca?

Although both psilocin and DMT are serotonergic compounds, each substance has a distinct character. Psilocybin tends to be gentler on the body, with less physical detox than ayahuasca. Psilocybin experiences are often described as playful and outward-focused, whereas ayahuasca journeys can be more introspective.We only serve psilocybin truffles at our centre — no ayahuasca or other plant medicines.

How should I prepare for a retreat?

Good preparation is essential. We recommend:

• Adequate rest

• Avoiding alcohol, drugs, red meat and heavy foods for one week

• Taking time for self-reflection

• Setting a clear intention

  
  

Once your intake is approved, we send detailed guidelines for preparation.

What are the contraindications?

Our retreats are for people in good mental and physical health. They are not a substitute for medical or psychotherapeutic treatment.

Psilocybin should not be combined with antidepressant or antipsychotic medication. Always consult your doctor if you are under medical care.

We cannot accept participants who:

• Are pregnant

• Have schizophrenia or psychosis sensitivity

• Have borderline personality disorder

• Are suicidal or severely traumatised

• Have serious cardiovascular or neurological conditions

Honesty in the intake form is essential for your safety and ours.
