Although this was announced last month at the beginning of this year's race, the news has been under the radar.
The Vuelta 2019 will start at a place that could be a perfect background for its Italian counterpart: the pink salt lake of Torrevieja, South of Alicante. The first stage is still to be decided if it will be ITT or TTT. The province of Alicante will also host stages 2 and 3, with Guillén remarking the abundance of mountains in the area.

Very little is known from the rest of the route. Guillén said that they had about 80% of it, but only two host towns have been aired:
Toledo will host a state finish as a tribute to Bahamontes in the 60th anniversary of his TDF win. IIRC he must be the oldest surviving TDF winner.

And Pau will host a mid race TT, with an additional stage finish on French soil.
