Willkamayu Spirit: An In-Depth Review for Ayahuasca and Wachuma Retreats in Urubamba, Peru

Willkamayu Spirit (Willkamayuspirit) is a small family-run retreat in Urubamba in Peru’s Sacred Valley, founded by Andean maestro Jhon Sikuri and Dutch inner-child facilitator Janneke Killanka, offering two to 12-day ayahuasca and Wachuma (San Pedro) programs for up to five guests from $345, per its Retreat Guru page. Guests rate it 5.0 on Retreat Guru and Google. Against that, it claims “professional screening by Doctor” but names no doctor or medical staff, publishes only a short medication note and no emergency plan, uses unnamed partner venues, and publishes no deposit or refund terms or company.

🎯 At a Glance

• Locations: Ahuanmarca, about 2 km from Urubamba town, Cusco region, Peru, with one Wachuma program in Yanahuara; the listings say they work with “carefully chosen” partner retreat houses, per its seven-day program page.
• Approach: One to three ayahuasca ceremonies and up to two Wachuma ceremonies led by Andean and Shipibo-trained maestros, with coca-leaf ceremonies, inner-child work, breathwork, family constellations, massage and online integration.
• Suitable For: Travelers in the Sacred Valley wanting a very small, personal group with integration support. Not suitable for people taking antidepressants or with heart or psychiatric conditions.
• Costs: $345 to $360 for two days, $567 to $597 for three, $964 to $1,024 for five and $1,377 to $1,467 for seven on Retreat Guru; $1,590 for seven and $2,650 for 12 on BookRetreats. No deposit amount or refund terms are published; the listings say “We will follow up about the deposit.” Transfers are not included.
• Overall Assessment: Very small groups, warm reviews and integration work, offset by an unsupported doctor claim, no published medical safeguards or emergency plan, unnamed venues and no published terms or company. Directory evaluation: C.

🔍 Critical Notes

Who runs it. BookRetreats presents Jhon Sikuri, from the Cusco highland community of San Pedro de Kacha, and Janneke Killanka, a former social worker from the Netherlands with more than a decade in Peru, as a married founding couple; their own profiles disagree on which of them founded the center, per Jhon’s profile and Janneke’s profile. Maestro Inonbari says he was born in the Shipibo nation and recognized as a maestro at 15, per his profile (unverified). Maestro Wayra also works with another Urubamba operator, Willka Pacha Experience. No website, social account or Peruvian company was found.

Screening and medical support. Event pages promise “Professional screening by Doctor and trained Therapists”, per its Wachuma program page, but no doctor is named and Janneke lists no formal therapy license. The only published guidance asks guests on mood-related or prescription medication in the past two months to get in touch before booking, per its five-day program page. No medical staff or emergency protocol is described. Urubamba’s public hospital is in town, a few minutes away (our estimate).

Listings. Seven-day prices differ between platforms, meals are described as vegetarian while tags include meat, and Retreat Guru lists a pool, spa and sauna that do not match the family-home and hostel settings guests describe.

Status. Operating, with retreats listed for November and December 2026 and a review from October 2026.

Legal context. Ayahuasca is legal in Peru, where its traditional use was declared national cultural heritage in 2008, and Peru’s reservation under the 1971 UN convention covers traditional San Pedro use; there is no licensing regime for retreat centers, per ICEERS.

🆘 Screening & Mental Health Risks

Ayahuasca and Wachuma in one program, with no published contraindication list, leave guests to judge their own risk. 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 Andean and Shipibo-trained maestros; the source is not published. Ayahuasca combines the Banisteriopsis caapi vine with a DMT-containing leaf such as chacruna, as Erowid explains.

📍 Location, Setting & Style

• Setting: The Sacred Valley near Urubamba, with gardens and a river, per its listings.
• Rooms: Private rooms for one or two with private or shared bathrooms in a family-home setting.
• Style: Andean ceremony blended with inner-child work, breathwork and family constellations.

Practical guidance: Fly to Cusco (CUZ) and take a bus or taxi to Urubamba, allowing time to acclimatize to the altitude; pickup is from the Urubamba bus terminal or a local hotel.

Should You Book?

Possibly, if you want a very small group in the Sacred Valley. Ask in writing for the screening doctor’s name and registration, the contraindication list, the venue’s name and address, who on site is trained in first aid, the deposit and refund terms, and the legal entity you are paying. Read our guide to verifying retreat facilitators.

The Team & Story

The founders describe Willkamayu as born from their own healing journeys and “a family bridging ancestral medicine and modern integration practices”; its gallery dates from 2024 and its earliest dated review from January 2026. We did not independently verify anyone’s training.

Prep & Integration Tips

Before you go: Disclose every medication and condition in writing and plan any change with your own doctor. After you return: Use the online integration community and arrange support from a qualified therapist at home. Our guide on how to research ayahuasca incidents can help you check any center.
