Comcaac (Seri) Bufo Alvarius Retreat

With Luis Miguel Lopez, Alfonso Morales Romero, Eva Evers and Agder Sanchez Palacios

November 5 - 10, 2023

We are grateful for the opportunity to share the beautiful medicine work of the Comcaac (Seri) people from Sonora, Mexico.

The Bufo ceremony is one of incredible intimacy, great depth, and beauty. It is an environment conducive to the free and unrestricted expression of the deep and abiding Love that unfolds during a journey of higher consciousness.

This is one of the most powerful entheogenic experiences a person can have, and often provides opening and revealing deep states of “source consciousness” within the Self.


We take a holistic approach to optimal wellbeing and spiritual development designed to deepen your experience and offer extensive preparation and integration support before and after focused on lasting results. During the retreat, we use several modalities to enhance your experience, such as movement, breath work and meditation. To help you feel at your optimal best organic and locally sourced (where possible) meals are included during your stay with us.

Each participant will be assessed before entering the program through a compulsory application form and screening. Due to the powerful nature of psychedelic ceremonies and the impact that others sharing the space can have, we limit this retreat to 10 selected people.

In the 4 weeks leading up to the retreat, we will virtually support you with your preparation.
