My definition of a day trip is somewhere you could conceivably visit in one day - even if that means getting up very early and returning very late at night. However, some of the trips recommended here are a little impractical if you want to return to Valencia the same day.
Situated just to the north of the Costa Blanca, Valencia is perfect for taking day trips to the beach. Beach holidays don't have to be lazy, decadent holidays - explore the coast and see a different beach every day!
