Arriving at the airport (VLC) it is easy to get straight on the Metro into Valencia.
Although, from passport control it is the furthest exit on the left but simply signposted
Then just a short escalator to the Metro ticket area where you can find ticket machines or a friendly ticket office. They speak basic English but it’s helpful to know your stop e.g. Estacion Nord, “ estación del norte” main station adjacent the city centre square “plaza del ayuntamiento“ (Town hall)
This Metro stop is only marked as ‘Xativa’ (Line 3 (red) and Line 5 (green)) so remember the station before, is ‘El Cid’ There is the usual route map above the exit, an LED sign for the next stop and a softly spoke verbal message.
Simple get-by Spanish is “Para Estacion Nord” with added “billete de vuelta” (literally ticket to return) as that just needs placing on the barrier reader, next time…
Even if you don’t use the train this is definitely a must to visit when in Valencia.
