I am trying to see what public transportation options are open for Sardinia. Renting a car is the last option.
I am familiar with how things work in Sicily - which is to say that trains are infrequent, and there are multiple bus companies.
I am planning to be Sardinia in October, and I am finding that some of the train sites like trainline and omio, are showing trains for September but almost none for October. I don't know about bus companies.
I want to hit Porto Torres, Castelsardo, Alghero, Olbia, Cagliari, etc
