Envibus, who run bus services in Antibes and as far north as Tourettes sur Loup and remote Gourdon area have an ‘Icilá’ service (Trans: ‘Here-There’!) offering an ad-hoc service in remote areas or where demand would be low at certain times. Other regions perhaps offer a similar service.
You call a free number - 0800 202 244- at least two hours before you want to travel, indicate the day and hour of your departure and where you want to be picked up and set down. The bus will collect you.
This service costs 1 euro – I will repeat that – ONE EURO.
I realise that the Icilá service is probably not intended to facilitate wily budget-minded tourists who want to get to, say, Gourdon, without paying to hire a car, but I would be interested to know if anyone has used it in an imaginative touristic fashion.
