Details of this retreat

An Odyssey retreat is an immersive, all-inclusive 4-day experience designed to maximize the benefits of psilocybin. Enjoy the comfort and serenity of a beautiful, natural setting and rest assured knowing our team of licensed facilitators is here to support you every step of the way. While your psilocybin journey will be inwardly focused, sharing the retreat experience with a group can be a unique opportunity to lean into the joyous and connective aspects of psilocybin. In September 2023, Odyssey made history by running the first-ever legal psilocybin retreat in the US.

Odyssey isn't just another retreat—it's an invitation for the intrepid spirit. For those who respect the power of science, yearn for profound personal growth, and seek to truly come alive, your journey begins here.

Life Altering and Meaningful Experience

It was a life-altering experience that exceeded my expectations. They prepared me extremely well for the journey and it is probably one of the best, if not the best, services to use in Oregon. The preparation and support stood out. I felt fully supported throughout the process. At first, I thought it was too expensive, but then I realized the amount of service and cost of legal compliance, and now I feel like it is a reasonable price.

An Experience That Radically Changed My Life

This was one of the most meaningful experiences of my life! The facilitators were excellent, empathetic, and sensitive to my needs. They helped me prepare for my psilocybin journey well. Each facilitator brought their own energy, experience, love, support, and insight—each one was unique and special. I felt fully supported throughout the process. My experience was an expansion into an awareness that has radically changed my life, and it was intentionally crafted by Odyssey. Every moment was designed to deeply support what I was going through, along with what the group needed. Nothing really to improve. It was top-notch.

An Outstanding Experience with Calm and Peace

I got a reserve of calm and peace, a reduction in anxiousness, and a sense of how to proceed forward on my chosen path. The facilitators were excellent, knowledgeable about mushrooms, and all 5 of them were superior. The integration care has been fantastic, and I felt fully supported throughout the process. I loved the group, the food, and the oneness. The offer of continuing contact and integration is just marvelous. Keep up what you are doing!

A New Perspective, Clarity, and Healing Beyond Expectations

I’m not sure I can put it into words, and much of it keeps unfolding. It has given me a new perspective, clarity, and healing that I didn’t even know I needed. It highly exceeded expectations. The facilitators were excellent, knowledgeable, and sensitive to my needs. I was truly blown away by the amount of space and intuitive support they provided. I feel the organization is professional, trustworthy, and the staff is highly trained. The facility and setting were warm and welcoming. The meals were delicious, nourishing, and adapted to my needs. I have celiac, and I didn't have to worry at all. I loved every aspect of my experience! And I've told many friends about Odyssey since returning home.
