Terra Mitica is truly a classic theme park, and not just because it offers some serious screamers such as the Infierno, Titánide, and shaky Magnus Colossus coaster. The theme is Ancient Greece, with period costumes, Herculean shows (some closed during low season), and plenty of other Olympian action.
Though the "Mythic Land" is an older theme park, its awesome collection of rides (many, like the Furía de Triton, offering a cool splash on a hot day) is guaranteed to keep kids happy, with options for everyone from young children to thrill-seeking teens.
Terra Mitica is located northwest of Benidorn, clearly marked off the Autopista, and easily accessible by car from town. However, parking prices are exorbitant, and it's easy to arrive by public transport. If you are coming from Alicante or elsewhere by rail, you can simply get off at the Terra Mitica stop and walk to the park. From Benidorn proper, it's cheaper and more convenient to take Bus 21 from either the downtown train station or Rincón de Loix (Rincón McDonalds).
