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.

March 7, 2023 at 11:51 amWe went together as a couple, this was our first experience with Ayhauasca and the world of alternative medicine using psychedelics so we were pretty nervous. Needless to say as you may have understood from other reviews that Yosi Ocha is a little slice of paradise on Earth. We were treated like family by the whole team since the beginning with Barbara managing our early communication till after the end of our retreat cheking on us. The team really went the extra mile to see that all our needs were met. The cerimonies were all very beautiful, meaningful and Maestro Heberto masterfully guides them with his beautiful icaros. We will come back 100% and bring relatives and friends since this is something everyone really should have the luck of experiencing. We really want to thank you all for your work in keeping the Shibipo traditions alive, taking care of the forest and spreading the love to newcomers. You guys are the best, gracias!

January 24, 2023 at 3:46 pmFor me Yosi Ocha was the perfect place for a first-time experience with Ayahuasca! I highly recommend the center and are already planning for my next visit.
Everything worked perfect, from the first contact and payment to pick up at the hotel in Iquitos, Barbara who manages most of the communication before you arrive at the center is very accommodating, helpful, and lovely in every way!
The center is located far away from Iquitos in the jungle, about 45 minutes to an hour by car and the last part of the road is a newly constructed sand road. The surrounding area of the center is dense Amazonian jungle, there is a route into the jungle leading you to the teacher trees. On the property you can visit cows and sheep and there is a variety of wild animals to be spotted. The feeling at the center is that of profound calm and peacefulness, no stress, or bad energies, just a wonderful place to be and disconnect from the regular world for a while. There is a natural pool of water on the property where you will take your daily aura cleansing flower baths, this is also a very relaxing place to sit and meditate or read.
The Maloca is big and roomy, it has adjoined toilets and a simple shower. Here you can spend your free time during the day, it is a nice place to meditate or just sit on your assigned mattress or in the sofas, you can even take a nap here or spend the night. The bungalows are exactly what you need, no more, no less, a bed with mosquito nets, toilet, shower, a cabinet for your belongings, a table with a water tank and a porch with a chair, table, and hammock. The dining area and other buildings are nice and a good place to chat with other passengers and the staff.
Maestro Heberto is a man of great energy, spirituality, and knowledge. Ines, Hebertos apprentice and helper, was wonderful, skilled, and really made me feel taken care of at the center. Hebertos family runs the center and are very helpful and hardworking. Ruben, the chef, made us food every day and it was delicious, simple but sufficient, mostly root vegetables, rice, veggies and fish or chicken.
The medicine is potent and healing, no one experienced any violent sessions or had “bad trips” during my stay. Maestro Heberto let us know what brew we were given and if it was a different one, he told us what to expect from that specific brew, since they can be different depending on how it is brewed. The center offers a variety of plant medicines apart from Ayahuasca, such as San Perdo, Rapé, liquid tobacco and toé.
All together Yosi Ocha is a wonderful place, and it is under development and will just become better in the future. Looking forward to my next visit to see how far along they have come.

January 11, 2023 at 1:02 pmMaestro Heberto is a master healer. Make an intention to heal self, and trust the Maestro to let the process unfold!
Other reviews posted here for Yosi Ocha capture very well the details around structure, facilities, organization, co-ordination of the booking & program. All I would add is if you encounter any hiccups, they safely hold your hands to clear them up for you. And everything on the website is very well captured representing the authenticity of this Centre and Maestro’s background, personality, practice, dedication to this art & science powered by sincerity and integrity.
Just as reaching any place of goodness such as a pilgrimage, it’s not an easiest of the journey to reach Yosi Ocha, but once you are there soak in the natural beauty & energy in this space and lose the sense of time. I believe Maestro & his team at Yosi Ocha, the nature in all its forms here have a loving energy with the potential to heal one and all. My best experience in life, till date… and I am grateful for it.

December 18, 2022 at 11:10 pmI wholeheartedly recommend this center. I couldn’t have asked for a better first experience with Ayahuasca and the other plant medicines.
Maestro Heberto is nothing short of a holy man. Full of heavy vibrations and deeply connected to Mother Nature, the spirits and the teacher trees. But he is still a fun, loving man and he gladly shares from his wisdom and his own experiences. He runs his center the way he sees fit and is very hands on with the whole organization.
Ines is a great helper and translator. Compassionate, knowledgeable and always willing to help. I am really grateful for her and the part she played in my stay.
Barbara was extremely helpful before the retreat. Answering all the questions I had and assisted me through the payment methods (as my bank was being a little difficult).
The location is perfect. It’s out in the jungle but not too far out. It’s very nicely kept by the workers and they continue working and building on the property. A path has been made to be able to see and connect to the teacher trees and you will also go there to give thanks and praises to them, the jungle and Mother nature.
It’s possible to get some internet but the connection is very spotty and only fitting to maybe send an email or two. I think this is great though, since I believe being connected with the outside world will only impair your healing. There is no reception on your phone, even if you have a Peruvian SIM-card. You can however go into Iquitos during the day if you need to fix something (book a plane ticket, make a call or whatever). The staff will help you.
One great thing is the food. Reuben cooks delicious meals everyday! Another great thing is that you can do laundry in a river on the property. This made it possible for me to only bring a backpack and skip the checked bagage.
There are animals running around (dogs, cats, chickens, ducks etc.) and many beautiful birds, interesting amphibians and insects. There are of course mosquitoes but I didn’t find them too annoying.
The bungalows are just what you need. A bed, a cabinet to put your stuff in, a table, a jug of water, a toilet and a shower. On the porch you have a hammock and a table with a chair.
The group sizes are small (which I really liked). When the center was full we were nine visitors. The medicine is potent and it worked very well all the ceremonies I was a part of. I won’t go into details on my personal experiences in this review and only focus on the center itself. But in short I learned alot about gratitude, detachment, patience and I had the opourtunity to work on my anger and anxiety.
I really enjoyed the San Pedro as a compliment to the Ayahuasca ceremonies. It helped me to contemplate and vocalize all the visions and insights Ayahuasca had given me. And also all the other medicines; rapé, liquid tobacco, toé, plant baths etc.
I (as a scandinavian ginger with sensitive skin) had some problems with the showering and bathing, as it itched alot afterwards. But that has nothing to do with the center, I just want to inform people that are in the same boat. I managed with some lotion though, so it wasn’t a major issue.
The schedule found on the website is only a reference. Heberto very much goes with the flow and does what feels right, not what has been previously determined. During my two week stay I had seven ayahuasca ceremonies (could’ve had eight but chose another medicine on the last ceremony) and two San Pedro-days, rapé and liquid tobacco a handful times, one 12 hour-long silent diet and I’m propably forgetting something.
So you will have your hands full your whole stay and always someone to help you, guide you and give you tips along the way.
If you visit with your significant other and both of you feel ready for it, I highly recommend the spiritual union ceremony. Heberto made a beautiful wedding for me and my wife and it touched both of our hearts deeply.
Me, my wife and a friend who joined us at the retreat are already planning to go back.

December 3, 2022 at 10:36 amWords cannot do justice to this place and my experience there. Maestro Heberto is so genuine, caring and skilled, I trusted him immediately. The treatment is about so much more than Ayahuasca, it’s a holistic approach, involving personalised medicines, depending on the patient’s specific needs.
I stayed for 11 days, and by the time I left it was hard to say goodbye, such was the strength of the bonds I formed there in a short time. The entire team contributed to making the stay special, and my fellow travelers were a beautiful group of people. A special mention goes to Ines, translator and Heberto’s assistant, for all her help. I was lucky enough to be there when there was both a kitten and a puppy to cuddle and play with 🙂
It will take months to process my experience, but some of what happened during my retreat goes beyond my understanding. I have been given instructions to continue my healing in the weeks and months following the retreat. If you are looking for a genuine shamanic healing with an unbelievably talented and dedicated curandero, Yosi Ocha is the place to go. I cannot recommend it highly enough.
