Onyx Retreats: An In-Depth Review for Ayahuasca Retreats in Vilcabamba, Ecuador

Onyx Retreats is a retreat center in Vilcabamba, Loja, in southern Ecuador, whose former website, onyxretreats.org, was titled “Ayahuasca Retreats in Vilcabamba, Ecuador” and advertised sponsored places, and whose Retreat Guru page describes plant medicine ceremonies guided by experienced shamans, with yoga, meditation and private rooms with en-suite bathrooms. It mentions an intake process and offers a $60 private pickup from Loja. Against that, no owner, shaman or company is named anywhere, it has no reviews on any platform, no prices, refund terms, contraindication rules, medical staff or emergency plan were found, the latest dated material is from 2024, and its website domain no longer resolves. We list it as an unverified operator.

🔍 Critical Notes

Who runs it. No one is named. Its eight-day program on Tripaneer sits under an organizer account named Nilaya Yoga, and the relationship is not explained. It is a different center from Ayahuasca Onixobo in Peru and from Casa del Sol in Vilcabamba.

Screening and medical support. Guests must complete intake before booking flights, but the intake content is not published, and no contraindication list, medical staff or emergency plan was found. Hospitals are in Loja, about 45 to 60 minutes by road (unverified).

Status. Probably dormant or closed; its website domain no longer resolved when checked in November 2026, its Retreat Guru page lists no events, and the latest dated material is a 2024 retreat page.

Legal context. Ayahuasca is not formally legalized in Ecuador but ceremonies are generally tolerated, per TripBase, and there is no permit regime for retreats. DMT is controlled under the 1971 UN Convention, while natural materials containing it, such as ayahuasca, are not, per Wikipedia.

🆘 Screening & Mental Health Risks

Confirm who leads the ceremonies and ask for written screening rules before booking flights. ICEERS notes that ayahuasca’s MAOI component makes it dangerous with SSRIs and other serotonergic drugs and that it is contraindicated for people prone to psychosis. Never stop a psychiatric medication to qualify for a ceremony without your prescriber’s guidance.

🧪 Brew Substance

Ayahuasca served by unnamed shamans; its source is not published. Ayahuasca combines the Banisteriopsis caapi vine with a DMT-containing leaf, as Erowid explains.

📍 Location, Setting & Style

• Setting: The Andean valley around Vilcabamba in southern Ecuador.
• Rooms: Private rooms with en-suite bathrooms for one or two people.
• Style: A blend of ceremony with yoga and meditation, in its words ancient practices with modern approaches.

Practical guidance: Fly to Quito, then to Loja; a private pickup with a bilingual driver costs $60.

Should You Book?

Not until the operator identifies itself and current dates are confirmed. Ask in writing who leads the ceremonies and their training, the price and refund terms, the contraindication rules, who on site is trained in first aid, and the emergency plan and hospital route. Read our guide to verifying retreat facilitators.

The Team & Story

Onyx presents itself as a place of holistic transformation through plant medicine. We did not independently verify anyone’s training.

Prep & Integration Tips
