Frequently Asked Questions - ►Information about staying at CERN

CERN is located on both sides of the border between Switzerland and France. The most commonly used currency is Swiss Franc (CHF) but payments may also be made in Euros (EUR). There is a UBS bank located on site and ATM’s are available. The CERN hotel accepts cash and credit cards.
PLEASE NOTE: In CERN’s restaurant, only cash payments in CHF (bills and coins) or Euro (bills only!) are accepted and all change will be given in CHF.

We will reserve double rooms (with toilet and shower; bed linen and towels are provided) in our CERN hotel for the duration of the programme. Please note that it is not possible to further extend your stay at the CERN hotel.

During the programme, you will have breakfast, lunch, and dinner at CERN’s Restaurant 1 (building 501) (opening hours: 7am until midnight; 7am-11pm during weekends).

In case of an emergency (fire, accident, etc.) at CERN you should call our Fire Brigade. The telephone number is 74444 (from any phone inside CERN) or +41 22 767 4444 (from your mobile). Our fire brigade is on call 24 hours a day, 7 days per week.

If you feel sick, which we sincerely do not hope, you can go to CERN’s ambulant medical service. Tel: 73186 or 78435 (from inside CERN), +41 22 767 3186 or +41 22 767 8435 respectively. The opening hours of the medical service are 08:30-12:00 and 14:00-17:30 on working days. If you have serious health problems outside these hours, please call the Fire Brigade (+41 22 767 4444).

At CERN, you can only smoke in specially-marked areas. All buildings (including the CERN hotel) are non-smoking.

If you bring a device with Wi-Fi card, you can access the CERN network by following a simple authorisation procedure (find more information on this website). You can apply for this in advance by following the procedure, with the laptop (or any other mobile device) that you intend to bring with you, using this link (Please add your CERN contact as guaranteeing contact person).

YES! You may take photographs of everything at CERN - but you will need a camera. So please do not forget to bring one with you!

Swiss power sockets look different from standard European ones - not to speak about those from Central America or other parts of the world. Please bring an adaptor to connect your devices to either Swiss or European power sockets.

During the programme you will visit many CERN facilities and also do a walking tour of the city as part of the programme. Please make sure to bring along both comfortable and suitable shoes. For safety reasons, high-heeled shoes, open-toed shoes, flip-flops or sandals are not permitted for the visits of the CERN facilities.
