From Saturday 22 May, the booking system will be in place until the end of the bathing season. Online reservations can be made free of charge from 20 May via www.visit-eislek.lu or the Éislek app. While in 2020 visitors only had to make reservations on weekends and public holidays, reservations are now mandatory on weekdays as well. Those who have already booked their tickets and then are unable to visit the booked beach area, should cancel their reservations by sending an email to firstname.lastname@example.org. Activities during which visitors do not stay on the beaches are excluded from booking. Accordingly, visitors do not need to make a reservation if they want to hike along the reservoir or go kayaking or fishing on the lake, for example. The current hygienic measures also apply when visiting the Upper-Sûre lake. Thus, a distance of at least 2 metres from other visitors must be maintained and when more than 4 people are gathered, the wearing of a mask is obligatory. The wearing of a mask and the physical distance of at least 2 metres do not apply to people who belong to the same household or who live together. Children under 6 years of age and persons with a disability or pathology who are in possession of an appropriate medical certificate are excluded from the mask obligation and the distance rule as well.
