4-5 day Psychedelic Group Retreat Programmes

We provide legal psychedelic retreat programmes with a 4-5 day retreat in the Netherlands as the focal point. Our programme has a pre-screening and integration process supported by our team of facilitators.

Our programmes combine best practice in psychedelic facilitation with the support of psychotherapy and a range of integration methods.

Our methodology is based on the work of Dr Stan Grof. We provide a safe container for you to maximise your experience with psilocybin in order to access your own inner healer.

We offer scholarships to those from socio-economic backgrounds who cannot afford the price of our retreats.

What to Expect

Stage 1:

Pre-screening

The Call

Once your application is submitted, our screening process begins. Each successful application will receive an hour consultation with a psychotherapist to ensure our retreats are mutually suitable and to answer any of your questions. Our retreats are not suitable for people who have had a mental health diagnosis (such as psychosis, schizophrenia, bi-polar, clinical depression or personality disorders, suicidality), cannot cease any psychiatric medication (ie SSRIS), or are dealing with serious addiction or substance abuse issues.

Stage 2:

Pre-departure

Intention – The Quest

Our pre-departure process allows us to communicate with all our participants, to answer any questions. We set an individual and collective intention and prepare for our journey. What is it that you intend to heal, how do you want to grow?

Stage 3:

The Psychedelic Retreat weekend

The Vision

Our experience retreats take place over five days at one of our beautiful retreat centres in the Netherlands. Participants are asked to make their own way to Amsterdam by 17:00 on the first evening of the retreat. From there we arrange transport to our retreat centre.

On the first evening of grounding and preparation, we set an individual and collective intention. What is it you intend to let go of, what do you intend to heal, how do you want to grow?

Our psychedelic sessions take place the afternoons of the second and third day, and are followed by two powerful days of integration using different therapeutic modalities from Art therapy to yoga. Our programmes are based on the pioneering work of Dr Stan Grof.

The retreat ends on the evening of the fifth day.

Stage 4:

Post-Integration

The Return: Embodying the Vision

Immediately after your retreat, we provide a one-on-one integrative consultation session to help you embody and integrate your experience.

A few weeks after your retreat, we will organise an online video conference for sharing, support, integration, and grounding. What have you learnt? How do you embody what you have learnt into your everyday life?

Why Psilocybin?

Psilocybin mushrooms have a long history of medicinal use, and are being investigated as a modern treatment for a range of mental health issues, such as depression, anxiety, addiction and PTSD. Studies show that they can improve psychological health in the long term, can create lasting personality change, making people calmer, happier and more open-minded. Their use are associated with lower levels of mental illness. Research shows that just a single dose of psilocybin can lift anxiety and depression for six months or longer. They may be effective in quitting smoking and help with relationship therapy. Not only do they help people with mental health issues, they have also been shown to help people who are already well to improve their lives. Magic mushrooms can reignite a sense of awe in the world and can reliably trigger a mystical or spiritual experience. In Ireland, where most of the Inwardbound team are from, magic mushrooms have a long ancestral history of being used as a medicine and spiritual guide.

Why InwardBound?

At InwardBound, our interdisciplinary team of psychotherapists, PhD scientists and holistic therapists believes in weaving together the threads of science and spirituality, knowing that the two ways are one. We work in the broad tradition of Dr Stan Grof – creating a safe container for people to access the wisdom of their own inner healer. We come from a long tradition of psilocybin use in Ireland. Our Celtic ancestors used the wild mushrooms of Northern Europe (Psilocybe Semilanceata) and worked with the patterns of nature for healing and spiritual growth and we continue that land-based ancestral tradition to create a modern context for psilocybin ceremony and reconnection with nature. We hold small groups with four facilitators (a balance of male and female) to a maximum of 12 participants. This very low ratio allows us to provide the highest possible standard of care for our participants using humanistic psychology’s core conditions of: empathy, being real and unconditional positive regard. Private rooms are available on most retreats. We do not claim to heal or fix anyone. Nor do we work with people in very vulnerable emotional, psychological or mental states. We do, however,  strongly trust in the power of psilocybin, the psychological process that unfolds on our retreats, and have witnessed many clients have transformative and life changing experiences.

Is it legal?

We work in the Netherlands, where the sale and purchase of psilocybin-containing truffles is legal, allowing us to work within the law.

Is it safe?

When used correctly, psilocybin is one of the safest drugs to consume, having no detrimental effect on long-term mental health.However, our programmes are not suitable for people with a history of psychosis, bipolar, schizophrenia, suicidality or suicidal ideation, clinical depression or a personality disorders, or who are dealing with serious addiction or substance abuse issues.
