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.

    Onikano, deep in the Allpahuayo-Mishana Reserve outside Iquitos, is unlike any other place I’ve sat with the medicine. From the moment I arrived in the jungle—picked up and brought into the family’s care—I felt held by something ancient and real.

    Maestro Niwen Koshi (Heberto García) and his Shipibo family create a container that is both fiercely traditional and deeply personal. The ceremonies, guided by his ícaros and the living lineage of the Merayas, cracked me open in ways I didn’t know I needed. Ayahuasca and San Pedro, the purification baths, the work with the palos maestros, and the quiet presence of the jungle itself worked together as one living process. There was no performance—only the medicine, the land, and people who have carried this work for generations.

    One of the most sacred moments was the beautiful marriage ceremony that Maestro Heberto held for us. Under his guidance, in the heart of the jungle, we consecrated our union with the medicine and the spirits. It was intimate, powerful, and deeply emotional—an experience that will stay with us forever.

    I left lighter, clearer, and more connected to myself, to my partner, and to the sacred than I have ever been. The experience was exceptional and truly transformational. Onikano is not luxury tourism; it is a place of healing and consecration with the medicine.
    I will keep returning.

    Thank you Maestro, his family and team.
    Amor y Luz,
    Nancy

    Having already experienced ayahuasca retreats in the jungle, I found Onikano special in its own way. The land is vast, deeply alive, and immersed in nature, with several master trees, a beautiful pond where you can swim, and a dedicated area for plant baths. The white sand throughout the property makes walking barefoot a real pleasure and deepens that feeling of connection with the land. Despite its size and wild surroundings, the place is very well maintained, and everything feels cared for with love and attention.

    For me, Onikano is a special place to connect with medicine but also reconnect with yourself and nature. There is so much space to walk, swim, meditate, and simply be. You can find your own rhythm, spend time in silence, and allow yourself to go inward without feeling that you need to fill every moment with something. The energy of the place is difficult to put into words, but it is something I felt from the beginning.

    I also appreciated the approach to the retreat itself. You will have all the support you need whenever you feel you need it, but this is not a place with a packed schedule of sharing circles and group activities. There are additional experiences, such as plant baths, mud baths, gatherings around the fire, tobacco ceremonies, and other opportunities to connect, but the emphasis is very much on your own process and integration rather than constantly sharing or collectively processing the experience.

    The place is very comfortable, you get your own bungalow with your private bathroom and shower. Food is delicious, nourishing, and cooked with love, adding to the overall feeling of being cared for. There is wife and plenty of areas to rest, relax, meditate and integrate.

    One other thing that makes Onikano particularly meaningful to me is that it is owned and run by Maestro Herberto, a local curandero who descends from the Meraia lineage. I deeply value being able to learn from and support someone rooted in the local tradition. After receiving so much knowledge, guidance, and teaching from these traditions, choosing a locally owned centre feels like a small but meaningful way to give something back. It matters to support the people who carry and preserve this knowledge, rather than choosing a centre run by foreigners.

    And then, of course, there are the people. From Maestro and Maestra to the translators, Barbara, and everyone working there, I felt welcomed and at home. There is so much care and love in the way things are done, and that makes a real difference when you are going through such a personal journey.

    Magic is still the word that comes to mind. I remain deeply grateful for the experience, the teachings, the people, and the land. ❤️

    Such a beautiful time at Onikano, I loved the Ayahuasca and San Pedro ceremonies, this is my second stay here. I love to swim in the hot lake, and there is also lots of natural wildlife, the food was also lovely to fresh fish or chicken most evenings. The facilitators were brilliant as was the maestro and his family. I was fully supported .
    It really is a paradise and I look forward to returning next year Thank you

    Mi experiencia en Onikano fue muchísimo más de lo que imaginaba. Llegué buscando respuestas y me fui profundamente agradecida, con una sensación de transformación, amor y conexión que es difícil poner completamente en palabras.

    Desde el primer momento me sentí acompañada y cuidada. Hay algo muy especial en las personas que forman parte del centro: el Maestro y cada una de las personas que están detrás, haciendo posible que uno pueda simplemente entregarse a la experiencia. Se siente la calidad humana, el respeto y, sobre todo, el amor con el que hacen su trabajo.

    Tuve además la enorme suerte de compartir este retiro con Gonzalo, mi pareja. Vivir juntos una experiencia tan profunda fue increíblemente enriquecedor para nuestra relación, pero también para cada uno de nosotros de manera individual. Siento que ambos volvimos diferentes, con otra mirada, más conectados con nosotros mismos y también el uno con el otro.

    Personalmente, regresé sintiendo un gran cambio interno. El Amazonas, la naturaleza, las ceremonias y todo lo vivido allí me llevaron a conectar con lugares muy profundos de mí misma. Volví con muchísimo amor, gratitud y una sensación de paz que todavía sigo descubriendo e integrando.

    Onikano, para mí, fue una experiencia que marcó un antes y un después, y que sé que voy a llevar conmigo siempre.

    Lo recomendaría 100% a quien sienta verdaderamente el llamado de vivir una experiencia de mejoría en su vida y esté dispuesto a hacerlo desde el respeto, la apertura y la entrega.

    Gracias Onikano. Ojalá muy pronto esté por ahí nuevamente ❤️
