ONIKANO

AUTHENTIC AYAHUASCA RETREAT – IQUITOS, PERU

Onikano is a traditional Shipibo Ayahuasca retreat set deep within the Allpahuayo-Mishana National Reserve, in the Peruvian Amazon — one of the very few centres still owned and led by the family whose lineage it continues. At its heart is Maestro Heberto García — known within the Shipibo tradition as Niwen Koshi.

That continuity shapes everything about the way we work:

• A safe, closely guided environment
A warm, family-run atmosphere, where every guest feels grounded and fully supported — with Maestro Niwen Koshi’s decades of experience present throughout the entire process.

• Truly personalised treatments
No two journeys are the same. Each healing process is individually tailored — honouring your unique history, needs, and intentions from the first day to the last.

• A living spiritual tradition
At Onikano, healing is not a spiritual spectacle. It is a living lineage — passed down through generations of Shipibo healers, and practised here with the same integrity it has always carried.

Many people arrive here after years of searching. What they find is a place where the work is real, the tradition is intact, and the healing is personal.

Each process has its own rhythm.

“This is my third time at Onikano.
Every time I return, I fall in love with the place even more.
My group loved it so much that two have already booked to return in the summer and another extended her stay for an extra 3 weeks.
I'm so grateful to have found OniKano and can't wait to come back.”

“I had been to other Peruvian ayahuasca retreats, but once I discovered Onikano and Maestro Heberto, there was no question of going elsewhere.
This humble, softly-spoken man is an extraordinary shaman. He is a man of great integrity and I trust him implicitly.
Sometimes ceremonies can be challenging affairs, but I know that with Heberto in control I am safe and need never be afraid.”

“I chose to return for a longer stay because my first stay was the most transformative experience of my life…
lo and behold, this second stay at beautiful Onikano has now become the most transformative experience of my life!
I was shocked and amazed by how much the additional week added to the experience.”
Eric STripAdvisor · July 2025

“I 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.
I felt very safe and loved.”
Kim FTripAdvisor · June 2025

“I have been there 4 times for multiple months. In 2023 my back pain had become chronic — the neurologist told me 'nothing to do but take pregabalin for the rest of your life.'
Instead, on a recommendation, I went to Onikano.
I love that this retreat is run by the local shaman. It's really about healing and not just about having visions.”
Christopher MTripAdvisor · March 2026

“I originally went for a one-week retreat and ended up staying for a full month.
During my time there, I felt like I truly found myself, a path, and a tribe to help guide me along it.
Magic is the word.”
AmaliaTripAdvisor · April 2026

“I had the blessing of spending 45 days at Onikano — it was a transformative experience.
The maestros are exceptional, deeply committed to their work and with an immense heart.
Every ceremony, every teaching, and every detail is handled with respect and love.”
ValentinaAyaAdvisors · February 2026

“I was looking for a traditional setting with a true experienced Shipibo curandero.
Onikano was the best choice ever.”

MAESTRO NIWEN KOSHI

(HEBERTO GARCÍA)

After guiding thousands of ceremonies over more than three decades, Maestro Niwen Koshi is respected for the depth of his knowledge, his integrity and the sense of safety he brings to the ceremonial space.

He was born into one of the oldest surviving shamanic lineages in the Peruvian Amazon, carrying the living legacy of generations of legendary Maestros. Within the tradition, his grandfather Yosi Ocha is remembered as one of the last Merayas — healers associated with the highest level of traditional Shipibo curanderismo.

His work is rooted not only in ceremony itself but also in a deeply personalised approach to healing — one that honours the unique emotional, physical, and spiritual processes of each person who arrives at Onikano.

Under his guidance, healing is approached with patience, integrity, and profound respect for both the plants and the traditions from which this knowledge emerges.
