Book online without payment (only in french)
Payment is made on-site on the day of your visit, not online!
No booking confirmation by email or phone; simply show up at the reception and give your name.
If you have a pre-paid ticket, a discount, or a gift voucher, etc., please make your booking as usual at the full rate. On the day of your visit, remember to bring your promo coupon, ticket, etc., so we can apply the discount.
It’s free for supervisors on the ground, no need to book a ticket for them.
Bring water, as there is no drinking water on-site. Remember to check our “prepare your visit” page
