Bufo Alvarius Retreat – Colorado Springs

With Ursula Sefic, Eva Evers and Sarah Howat

September 27 - 30, 2024

We will be staying in a beautiful, private property immersed in nature at the outskirts of Colorado Springs, CO. The center is an intimate place with lots of natural light and an open communal space. The ceremony will take place inside by the fire place surrounded by the majesty of the natural surroundings outside. Amenities include hot tub and lake access.


In the vast expanse of the Sonoran Desert, where ancient wisdom flows, resides the indigenous community of the Comcaac people, also known as the Seri tribe. Their spiritual practices are deeply rooted in their relationship with the natural world, and one aspect of their traditional spirituality involves the use of the enzyme of the Bufo Alvarius, a species of toad commonly referred to as the Colorado River toad or the Sonoran Desert toad.

The spiritual use of this enzyme among the Comcaac people is not taken lightly. It is considered a sacred practice that requires proper initiation, preparation, guidance, and respect for the toad, its life, and the spiritual realm it represents. The ceremonies are conducted with the utmost reverence, emphasizing the importance of intention, humility, and a deep understanding of the interconnectedness of all beings.

The experience induced by Bufo Alvarius is highly intense and transformative, often leading to profound spiritual insights, expanded consciousness, and a sense of unity with the universe. The Comcaac people believe that it allows them to connect with the spiritual realm and receive guidance, healing, and wisdom from their ancestors and the natural forces that govern their lives. We honor the tradition of the Comcaac people, their wisdom, and the ancient ways embedded in this practice.

During this retreat, Ursula, a representative of the tribe, will join us to share this sacred ceremony for the purpose of spiritual healing, answers, and guidance. Although it is a relatively short ceremony, approximately 45 minutes, the effects can be felt and experienced long after the ceremony has concluded. Therefore, we devote a significant amount of time to preparing you for the ceremony, as well as for grounding and integration afterward. This spiritual medicine has the power to reset your system and, consequently, to change lives.

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 participants.

By supporting indigenous cultures through our reciprocity efforts, we acknowledge and honor the relationship between them, the sacred medicine Bufo Alvarius and the outside world, striving to create a harmonious cycle that benefits all. We, also, support preservation projects for this sacred medicine for future generations.
