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 impacting experience

Over two years I searched for information on a safe, psychedelic experience. It included looking at a handful of companies. Odyssey stood out in the early stages because of the authentic, simple information provided. I was not wrong. Once I chose them, they took me step by step toward my journey. They screened me, I screened them. They provided information to set the right intention. They held one on ones and group preparation meetings on Zoom. I felt safe and informed. Indeed, the trip to Bend, OR was everything I intended because of Odyssey's preparation and caring. I'll do another trip one day and won't hesitate to have them be my partner again. Oh, and did I say their facilitators are caring, authentic people who want the best experience for everyone.

A First-Class Retreat

Odyssey offers a 1st class retreat and healing journey. Location was beyond my expectations. Our lead facilitator was hands-on the whole time. He seemed genuinely empathetic and interested in us getting the best experience we could. The chef was amazing and made incredible food. The bond between clients was crucial and promoted by the facilitators. Worth the investment!

A Journey to My Inner Self in a Beautiful Setting

I’d describe my experience with Odyssey as a journey to my inner self, supported by skilled facilitators in a beautiful setting. I loved the people, the sharing, and our connection. I cannot think of anything Odyssey could improve.

A Life-Changing Week

The whole week changed my life in a profound way! All of the facilitators were phenomenal, caring, loving, and held space for us. The sessions outside the ceremony were thoughtful and meaningful. The house was fantastic. The food was WAY beyond expectations. Everything actually highly exceeded my expectations!
