Practical advice for safe swimming in the Jura

Summer and swimming are synonymous with relaxation, but safety must always remain a priority. Never swim alone, even if you are a good swimmer, and always keep an eye on children, even in shallow areas. Choose supervised beaches and follow the lifeguards' instructions.

To preserve the ecosystem of the Jura lakes, avoid using polluting sun creams, do not trample on areas of aquatic vegetation and do not leave any rubbish on the banks.

Finally, if you choose to swim in a river, find out in advance about authorised areas and the risks of currents or flash floods, and remain particularly vigilant, as these sites are not usually supervised.
