🔍 Critical Notes
Welcome to Oka Wasi!
A warm welcome
Welcome to Oka Wasi, nestled in the foothills of the Andes, just 10 km from the city of Tarapoto. Founded in 2013 by Yann Riviere, our healing center draws its inspiration from his nearly decade-long initiatory journey alongside traditional Shipibo healers in the Peruvian Amazon. It was this journey that inspired Yann to leave the suburbs of Paris to venture into the Amazon, giving birth to the idea of the center.

Open to the public for over a decade, Oka Wasi has already welcomed several hundred people for shamanic retreats, thereby making the benefits of these unique experiences accessible to individuals from around the world in search of healing, personal development and deeper spiritual understanding. By sharing the teachings derived from encounters with shamans, ayahuasca and master plants, our mission extends beyond mere individual care. We aspire to preserve and disseminate this ancestral knowledge to future generations.


By sharing the teachings derived from encounters with shamans, ayahuasca and master plants, our mission extends beyond mere individual care. We aspire to preserve and disseminate this ancestral knowledge to future generations.
We firmly believe that this wisdom represents a genuine treasure, essential for confronting the challenges of the world of tomorrow, while assisting numerous individuals in better understanding the relationship between humanity and the environment that surrounds it, and in finding their place in the history of this world.

Our Vision
The Amazonian medicine of ayahuasca, master plants and the related ancestral traditions have succeeded to endure to this day despite the threat of globalization that could relegate them to folklore. Simultaneously, our current society is facing a significant decline in spirituality, prompting many individuals to turn to ancestral traditions. In the Amazon, these traditions are considered a form of medicine, as they acknowledge that any lack, discomfort or illness fundamentally stems from a spiritual or energetic imbalance that is essential to restore. The realization of a endangered tradition and a modern society seeking to reconnect with nature, especially with the divine and the soul, has driven us to take on the challenge of creating a spiritual center to preserve and share this medicine and the surrounding tradition.

Over time, the awareness of the significant contributions these traditions can make to the modern world and the connections it maintains with the soul and the surrounding world has become evident. Ayahuasca is not a panacea in itself, despite its numerous benefits for self-understanding and understanding our world. On the contrary, this plant even presents certain risks. However, the consumption of ayahuasca is not the core of the Amazonian tradition; it is rather the diet of master plants and the accompanying teachings that define the richness of this medicine.
The vision to protect and share this medicine is no longer just a dream, and we are delighted to welcome you among us to experience this unique journey that has already allowed many individuals to overcome various types of mental, emotional, physical, or spiritual blockages, where modern medicine sometimes failed. Our approach to this medicine is deeply traditional, based on years of experience and learning from Shipibo shamans. Simultaneously, it is holistic, integrating various approaches such as psychology, meditation, yoga, and spirituality. This integration of different methods reflects our commitment to preserving a synergy of sacred tools that are both alive and contemporary, allowing them to evolve with us and the world around us.

Reviews
I went to Oka Wasi with high hopes, desperate for a breakthrough after years of feeling stuck and disconnected. The setting is undeniably raw and real—there’s no pretense here, just a gritty focus on deep healing. The Ibogaine ceremony did offer moments of profound clarity; I experienced a few flashes of insight that helped me see the roots of my pain.
But the overall experience left me feeling a bit let down. The organization was pretty disjointed at times—sessions started late, and I often wasn’t sure what was coming next. The accommodations were extremely basic, and while I appreciate that this isn’t meant to be a luxury retreat, the lack of proper upkeep made it hard to fully relax. Additionally, while the facilitators are knowledgeable, I felt that the group size was too large, which meant less individualized support when I needed it most.
In short, the medicine itself is undeniably powerful, but the logistical chaos and lack of personal attention meant I didn’t get as much out of it as I hoped. If you’re considering this retreat, be prepared for an intense experience that might require a lot of patience and self-reliance.
My experience at Oka Wasi was, overall, a powerful journey of self-discovery and healing. The center has a very no-frills vibe that emphasizes raw, unfiltered work. I appreciated how the facilitators were straightforward—no sugarcoating, just honest guidance. I had some amazing breakthroughs during the ceremony that helped me face years of buried pain.
However, I did run into a couple of hiccups along the way. The schedule was a bit chaotic at times; I found myself waiting longer than expected between sessions, which left me feeling a bit off my rhythm. Also, the accommodations, while clean, were very basic—nothing luxurious, just functional. Despite these minor issues, the overall impact was undeniable. I left feeling more centered and clear-headed, with new tools to handle my challenges. If you’re looking for deep healing and can roll with a few bumps, Oka Wasi is worth it.
Yo, I wasn’t expecting anything magical when I booked my session at Oka Wasi—honestly, I was pretty skeptical. But man, was I wrong. This place isn’t about Insta-perfect vibes; it’s about real, gritty healing. The moment I arrived, I felt a heavy, grounded energy that instantly told me, “This is where it’s at.”
The Ibogaine ceremony was wild. There were moments when I laughed uncontrollably and others when I just sat in silence, staring at my own reflection. Dr. Martin and the team guided me through every twist and turn with no-nonsense empathy. I’ve never felt so raw and real—like I was finally allowed to break apart and rebuild myself from the inside out. The integration sessions afterward were equally intense, full of deep group discussions that helped me piece together my revelations. I’m six months clean now and forever grateful. This isn’t for the faint-hearted, but if you’re ready to get real with yourself, give it a go.
I came to Oka Wasi at the very bottom of my life—years of addiction and heartache had left me numb and hopeless. I wasn’t sure if Iboga could truly help me, but from the moment I stepped into their space, I felt something shift. The center’s environment is raw yet nurturing; it’s not some fancy spa, but it’s real, and that’s what I needed.
The ceremony itself was intense. I remember lying there, feeling every emotion I’d suppressed for so long. The facilitators didn’t sugarcoat anything—they were brutally honest and kind at the same time. I can still recall Dr. Martin’s steady voice guiding me through a moment when I thought I couldn’t go on. By the end of it, I felt like I’d shed a lifetime of weight. I left Oka Wasi with a clear mind, a lighter heart, and a glimmer of hope that I could rebuild my life. For anyone on the edge, ready to face your darkest parts to find the light, this place is a lifeline.
I came to Oka Wasi after years of dealing with anxiety and unresolved trauma. The environment there is stripped down and genuine—it’s all about getting to the heart of your issues, no frills attached. The Ibogaine ceremony was a rollercoaster: moments of intense, almost overwhelming vulnerability interspersed with flashes of clarity that made me see my life in a new light. The staff, especially Dr. Martin, were both compassionate and firm, which was exactly what I needed.
That said, the experience wasn’t without its minor drawbacks. The integration process, while helpful overall, sometimes felt rushed; I would have appreciated more one-on-one time to fully digest my emotions. Also, some logistical details, like the timing of sessions, could use a bit more structure. Still, if you’re ready for a raw, honest dive into healing, this retreat offers a transformative experience that I’ll always remember.
