There is a taxi service at the airport serving all areas. There is also a direct bus service from the airport to Benidorm which leaves from the airport at set times throughout the day, costing only 6euros this would help to keep taxi prices down.

Hiring a car, for collection at the airport is an inexpensive option (at approximately £100/week in low season) and will give you the freedom to explore the area and all it has to offer more fully.
