The main train station in Antibes, it's located about 15 minutes walking to old town, and about…read more7-10 minutes from Port Vauban. (There are also a few bus lines though it's more convenient to walk since most of the narrow streets are pedestrian only.) The station is pretty clean and decent sized for supporting only two rail tracks--one headed East and the other West--along the coast.
Train arrival and departure information is posted on screens outside and inside the station. Ticket machines may take a little bit of time (maybe 5-10 minutes) to figure out a) if you haven't used them before, as there are two different types of machines, and b) especially if you don't read French or aren't familiar with any Romance languages, since the preliminary navigation screens are in French. So plan your time accordingly if this is your first time taking a train in the south of France. I'd recommend purchasing a ticket directly at the station since the one I bought online on their app couldn't actually be used. When I tried to scanning the ticket QR code (from my phone) on the digital scanner for entry to the platform, it wouldn't work.
During normal business hours, there are a few spots inside to purchase convenience items, snacks and drinks. There is an inside waiting area with benches, and if you're waiting outside the platform is covered overhead. Bathrooms are available in the form of public toilets which are I believe €0.50 per use.
Taxis are readily available outside the station in the mid-morning and early evening times when I arrived and departed Antibes.
