Onikano is one of the very few ayahuasca retreat centres still owned, led, and inhabited by the same Shipibo family whose lineage it was built to honour.
Located in the Allpahuayo Mishana National Reserve, 22 km from Iquitos, Onikano operates within a living Shipibo healing tradition under the direct guidance of Maestro Heberto García — known by his Shipibo name, Niwen Koshi. His grandfather, Yosi Ocha, was regarded as one of the last Merayas: healers who reached the highest level of traditional Shipibo curanderismo. That lineage is alive at Onikano today.
What makes Onikano different is the deeply personalised nature of the work. Each guest is received as an individual, not as part of a standardised retreat formula. After an initial personal evaluation, Maestro Niwen Koshi designs a healing process that takes into account each person’s history, needs, intentions, and energetic condition. Guests may come for one week or remain for several weeks or months, depending on the depth of the work they feel called to undertake.
Retreats at Onikano are rooted in a broad range of traditional Shipibo practices: ayahuasca ceremonies guided by ícaros, plant dietas, purification baths with plants and flowers, ancient rituals and work with the palos maestros, or teacher trees. Alongside this Shipibo foundation, Onikano offers San Pedro (huachuma) ceremonies — a tradition that Maestro Niwen Koshi learned from Andean maestros and integrates as a complementary path within the healing process.
Onikano sits deep within the reserve, one of the most biodiverse ecosystems in the Peruvian Amazon, characterised by majestic trees, red-water streams, and distinctive white-sand forests. The centre includes private bungalows, a traditional ceremonial house, a lake for swimming, and a cosy dining room where guests share meals prepared with fresh, local ingredients.
People come to Onikano for many reasons. Some arrive for their first encounter with ayahuasca. Others return year after year. Some stay for a week; others enter a longer path of healing, dieta, or shamanic apprenticeship with Maestro Niwen Koshi. What they all share is a sincere willingness to work deeply and respectfully, with trust in a tradition passed down through generations.
Onikano is not the right place for everyone. It is the right place for those who are ready to do real work. If that resonates, the journey begins with a personal application.

August 1, 2025 at 7:45 pmFirst off, let me say, I have tremendous gratitude for everyone working at the retreat: Maestro Heberto, Ercilia, Eunice, Doro, and Herminia, among others, for the level of care they provided throughout this experience. I was freaking out before arriving, as I had no previous experience with aya, but the minute I set foot in Onikano, I felt immediately safe and comfortable, its like life made sense while I was there. The center has a really good energy and you feel it the moment you arrive. The nature is sublime, premises have exactly what you need and the food was amazing, I was expecting it to be much more bland due to the dieta, but every meal felt like a treat.
About my experience:
I spent a week in Onikano in February, mostly wanting to heal on OCD issues and Self-Love. I’m not a very spiritual person, and certainly not good at giving up on control, but I convinced myself to do ayahuasca after seeing great results with close friends. I was freaking out before my first ceremony, but after the first one, fear was gone and I enjoyed every minute of my week at Onikano (except San Pedro Day, which I believe its not for me lol).
My experiences were profound, not necessarily easy, but certainly necessary. I felt Maestro Heberto really knew what he was doing and was treating everyone like a doctor, connected to each and every one of us and our needs. We were all connected in ceremony, we were all one. I don’t really know how to describe the experiences or whether it’s relevant, but what happened there was definitely the most profound experience I’ve ever had on my life. I connected with my deceased grandma, died and then resurrected, and then die again, it was definitely a ride and not an easy one.
The 4 ceremonies were all very different, first one I felt I did not connect with the medicine, as I didn’t see much, however, after a few months might have been the most relevant one. A lot of its makes sense after a few months I guess.
One caveat for me and that not many people talk, is about what happens after a retreat, the famous ‘integration process’. If you decide to go this healing route with abuelita, you need to be prepared for everything that unloads after the retreat, as it hasn’t been easy for me at all. In my experience, I was really vibing high after all my ceremonies in the retreat, even after some difficult ones, like I overcame some specific fear or discovered some sort of higher truth, but after I left the retreat, the 1st two weeks were amazing, and then I felt sort of going down, energy drained and my OCD suddenly increased. I’m currently accompanying the process with my psychotherapist, who’s been amazing at making sense of all these emotions and sensations, and yes, despite how painful its been, this follow-up process feels like growth, but hasn’t been easy and you need to be prepared for that, as I wasn’t. I felt after the retreat like I didn’t need therapy anymore, as everything made sense now, and no. The fall was hard. the past few months feel like I’m unloading a lot of past emotional baggage, while it feels healthy and some necessary work, at the same time its been very energy consuming and not the easiest of processes, and its been like this for at least a few months now. Maybe next time, I really need to do the recommended two weeks? Maybe it’d be a good idea to incorporate integration sessions? I don’t know…
As you can see, I’m still trying to make sense of this spectacular experience, so removed from anything I’ve known or done. Either way, all emotions and energies are mine, and you just gotta be accountable for them. Right now, I haven’t been able to get rid of fear, but some good has come from this experience, e.g. I stopped drinking alcohol all of the sudden after the retreat ( and I used to drink quite a lot), alcohol doesn’t make much sense for me after what I saw on the ceremonies and breaking this habit has been very helpful for my integration process.
In conclusion, If you got the call, I can only recommend Onikano and Maestro Heberto for your healing journey.

June 2, 2025 at 12:21 pmI had the perfect experience during a one week stay. I understand why it is recommended to stay longer now and I only wish my current lifestyle and situation allowed me to stay longer. Everyone is so selfless and caring, so dedicated to sharing their wisdom and ensuring every guest is comfortable and safe. The translator Ones was very sweet and accommodating. The Maestro was very wise and powerful. The Maestras were also very wise, powerful and caring. I felt very safe and loved. Ceremonies were very special. The food was delicious and very nourishing. The property was very clean and well maintained. I very much recommend this place. I am sure to return one day.

May 28, 2025 at 6:11 pmI visited Onikano for 2 weeks. This was my 2nd visit, last year I spent in Onikano 1 week. Both times the experience was powerful, meaningful and healing. I allowed the medicine to do its work and was open, excited and present with the medicine, teacher trees, the healers and self.
This year I experienced the medicine in a very powerful and meaningful way. It was transformative!
The retreat felt intimate, safe, loving, caring, healing and even fun.
We had an amazing fire ritual, opening of the back portal and even a boat cruise. The Maestro and Curanderas were attentive and always there to guide us. Ines, translator, was absolutely amazing.
For me, Onikano is a sacred place for healing that can help you to lead to many transformations. I believe that the key is to being open and judgment free.

May 25, 2025 at 2:00 pmAfter my third miscarriage, I chose to travel to Onikano to replenish my physical, mental and spiritual state. The Onikano team was incredibly warm and welcoming. They were attentive and deeply caring. You can feel it in their words and their actions. The experience wasn’t just the ayahuasca, it was a wholistic approach to my general well being in a very customized way. They provided a few other herbal remedies for my specific conditions. I stayed one week and left feeling rejuvenated, lighter and brighter in spirit. Fast forward a few months, I am now 18 weeks pregnant with a healthy baby.
This place isn’t for everyone, but if you’re feeling stuck, completely depleted, in need of a reboot/cleansing of energy, I highly recommend considering Onikano.

May 9, 2025 at 10:17 amI recently had the privilege of attending the Onikano ( former Yoshi Ocho) Ayahuasca retreat, and I must say, it was an absolutely amazing experience that I wholeheartedly recommend to anyone seeking a transformative journey. From the moment I arrived, I was enveloped in a warm and welcoming atmosphere that set the tone for the entire retreat.
The people I met at Yoshi Ocho were truly incredible. Each person brought their own unique energy and stories, creating a vibrant and supportive community. It was a joy to connect with such diverse and inspiring individuals, all of whom contributed to the enriching experience.
One of the most remarkable aspects of the retreat was the presence of the Shipibo tribe. Their wisdom, traditions, and deep connection to the land added an invaluable dimension to the experience. The Shipibo people are truly amazing, sharing their culture and insights with such generosity and warmth. Their ceremonies and teachings were profound, leaving a lasting impact on my journey.
The food at the retreat was thoughtfully prepared to be dieta-friendly, featuring meals with little to no salt, an abundance of fresh vegetables, and the most delicious fruits I’ve ever tasted. Each meal was a testament to the retreat’s commitment to nourishing both the body and soul, allowing us to fully embrace the experience while maintaining a healthy and balanced diet.
Overall, my time at Yoshi Ocho was filled with moments of profound connection, personal growth, and pure joy. The retreat offered a perfect blend of relaxation, introspection, and community, leaving me with cherished memories and a renewed sense of self. If you’re considering a retreat that offers an amazing atmosphere, wonderful people, delicious, health-conscious food, and the incredible presence of the Shipibo tribe, Yoshi Ocho is the place to be. I can’t wait to return and experience it all over again!
