Mission & Vision

Psychedelic Retreat Programmes

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

Evidence-based scientific research shows that psilocybin may improve mental health. Our programmes combine best practice in psychedelic facilitation with the support of facilitation 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.

Enriching Experience
I had a truly transformative experience at the Outward Bounds retreat. The facilitators were exceptional — supportive, friendly, and deeply respectful, creating a safe and caring environment throughout. The journey itself heightened my senses and deepened my appreciation for the beauty and blessing of life, while helping me recognize the futility of anger and hatred.
It was a powerful reminder of connection — with nature, with others, and with the stillness within. I’m deeply grateful for the insight and peace I gained through this retreat. Highly recommend to anyone seeking clarity, renewal, or a fresh perspective on life.

A transformative experience
I can't recommend Inwardbound highly enough. The team have put a lot of thought and care into creating a safe and nourishing environment focussed on facilitating individual healing journeys within a supportive group context. There is an impressive attention to detail coming from a deep understanding of the processes involved and learning from long experience of running the retreats. Rob, Renée and Lauretta were perfect facilitators - professional, compassionate, accomodating, and simply great human beings committed to enabling transformative experiences for everyone who attends. Thank you 🙏
