The Val d'Allos has, until very recently remained within Barcelonette’s sphere of influence and the exchanges between these valleys were plentiful. It was only in 1890 that a road replaced the poor mule track linking the two communities.In 1903, Alpine coaches pulled by horses connected Barcelonnette to Allos over a 6-hour journey, with a 1-hour break at the refuge on the col to allow the horse to recover.Finally, just before the war, in summer only, an Ubaye transport company provided travellers with a daily return service between Barcelonnette and Allos, along a road which was now tarmacked, at last using coaches which had tyres.
