YOSI OCHA reserves the right to determine if you are suitable to receive treatment and attend ceremonies or other activities at our facilities. To do this, you must complete the Retreat Application Form on our website where you will have to answer a series of sensitive information regarding your physical and mental health. YOSI OCHA will not share this information except with the people at the centre trained to evaluate your request. YOSI OCHA will trust the veracity of your answers in the Application Form and will not be responsible for any falsehood or omission in them.


Once you book your retreat and make your travel arrangements, you must provide the YOSI OCHA team with the details of your arrival flight to Iquitos, your departure flight from Iquitos, or the hotel in Iquitos where you will be staying, so that we can coordinate your pick-up on the day of the beginning of your retreat. It is the client’s responsibility to verify their reservations and necessary documentation for the trip to Peru and make sure that the details provided to the Yosi Ocha staff are correct.


It is possible to make secure payments through our online platform with PayPal. In order to pay through PayPal, it is not mandatory to have a PayPal account, you can also pay with your credit card through the same platform. Outside our web platform, you can pay by PayPal, Wire Bank Transfer or Western Union.

To reserve a retreat, you must pay 30% of the total amount, the remaining 70% should be paid the latest 30 days before your admission to the centre. Regardless of the payment mode, 30% paid upfront for the reservation is non-refundable in case of cancellation by the client. See the section “Cancellation” to find out the percentages applied according to the cancellation date.


The total number of retreat days is counted including the day of arrival and the day of departure, regardless of the time at which you access the center and the time you leave. Officially, the retreat is terminated after breakfast, at 10 am on the last day.


Any additional day outside of your scheduled retreat has an additional cost, depending on the length of your stay. The extension of your retreat will be subject to our availability. The additional days should be paid at the moment of the booking, preferably in cash. If, however, you need to use the Internet to make the payment, we can arrange a short trip to Iquitos so that you can settle the payment and then continue with your retreat.

In case you decide to reduce your stay and depart from Yosi Ocha earlier than scheduled, please note that you will NOT be entitled to reimbursement for the remaining days of the retreat.
