Come to the Circuit is very easy with Renfe Cercanías (suburban trains). During the whole year you only have to take line C3 of Cercanías Valencia. The Circuit's halt is the first stop after Loriguilla-Reva (if you come from Valencia) and the first stop after Cheste (if you come from Buñol).
About Line C3
Line C3 going from the València Nord Station to the Circuit finishes in San Isidro area because of the new arriving of the AVE. For this reason Renfe and Metro Valencia have reached an agreement that allows people using Line C3 use also Metro Valencia vehicles with the same ticket. This agreement only includes the four stations of Metro Valencia nearest to València Nord Station and the center of the City: Valencia San Isidro, Plaza de España, Bailén and Colón.
Users going from the Circuit to Valencia have to transfer themselves to Metro Valencia vehicles when reaching Sant Isidre Station, and from there they can use Line 1 of Metro Valencia to reach Plaza de España Station or Line 5 of Metro Valencia to reach Bailen or Colón Stations.
Users going to the Circuit from Valencia have to reach Sant Isidre Station from one of these Metro Valencia Lines and there they can transfer to Line C3 and follow their trip to the Circuit.
IMPORTANT ADVICE: The train stops at the Circuit's halt in the weekends but not from Monday to Friday, except during the MotoGP Grand Prix when an special service is provided.
