On 31st May and 1st June, road traffic will be severely disrupted due to security measures for the Franco-African summit taking place in Nice.
In order to make traveling in the region easier, rail service SNCF is increasing the number of seats available by 3500 a day. It's also introducing an all day ticket for the regional TER trains tomorrow and Tuesday. Each day pass costs 5 euros and allows unlimited use of the TER network between Cannes, Drap and Monaco. Tickets are available from the automatic machines in Monaco.
