From Stansted you can’t fly directly into Valencia (airport closest to Benicassim), however you can fly to Alicante (only 2 and a bit hours by car/train to Beni) for rock bottom prices, and we mean rock bottom! At time of writing EasyJet were offering return flights (incl. taxes etc.) from Stansted to Alicante for just £69, now that’s ludicrously cheap if you ask us! Although just remember you might have to pay a bit extra on top of that for any hold baggage that you’re taking – trust us you WILL need hold baggage, especially if you’re camping. You might actually find better flights prices from Heathrow or Gatwick, but it depends on how close you live to each airport as to whether it’s worth it.
