Registrations and Payments

To book your activity:

We cannot guarantee the feasibility of activities without prior reservation within a reasonable timeframe.

Send an email via the "Reservation" page no later than 5:00 PM the day before your activity.

The person making the activity reservation and registering other participants under their signature is responsible for ensuring their compliance with obligations. If the date is available, we will record your activity request and send you your ticket by email. Payment of a deposit, including the reference from your ticket, confirms your reservation and activity.

Based on the date of receiving your activity request:

Your price offer is valid for a maximum of 30 calendar days or Up to 7 calendar days before your chosen activity date or Until the payment of your deposit (which must reach us before the expiration of your price offer), considered as confirmation of your activity. Your offer can be modified up to 2 times without administrative fees. Your price offer is based on the number of participants provided. If the total number of participants is modified (unless explicitly agreed otherwise) by adding or removing participants, we must be notified no later than 10 days before the activity. Any unreported increase in the group size will be automatically charged on the day of your activity at the listed rate. The remaining balance must be paid no later than the day of your activity and BEFORE it starts, except for associations, companies, or school groups: the full payment for your activity must be made 72 hours before the activity.

Accounting documents justifying your payment will be provided upon payment.

For reservations made less than 30 days before the activity, the deposit must be paid within one week of receiving the offer and at least be present in the bank account of the company 13ZENLF, 72 hours before the activity, unless otherwise agreed in writing. Please have proof of payment in either paper or screenshot format as we are in an area without 3G/4G, and downloads are not possible.


The prices mentioned on our website and brochures are valid from January 1st, 2023. They replace prices published in previous publications. In case of significant price changes beyond our control (transportation costs, taxes, imposed fees, etc.), if the price increase exceeds 10%, the participant has the right to cancel their registration without any charges and will be refunded the amount already paid. Partner offers/group benefits, etc., cannot be combined.


Cancellation by Participants:

As a participant, you have the right to cancel a registration. However, please take note of the following cancellation fees: Beyond 7 calendar days: 50% of the price. Less than 7 calendar days or no-show: 100% of the price.

Any cancellation must be notified in writing.

To avoid cancellation fees, you may find a replacement yourself. In this case, both you and the person taking over your reservation are jointly responsible for fulfilling all obligations, pre-agreements, and any associated costs arising from the transfer of the reservation.

Any transfer of reservation must be done in writing to the following address:


In the event that you or the participants have decided not to proceed with or were physically/mentally unable to complete the reserved activity, no refund can be claimed.

An activity fully paid for online does not give rise to a refund, even in the event of non-presentation of all participants stated on the ticket.
