Great castle, nice beach, shopping, museums, nightlife; Alicante is the centre of the Costa Blanca. Here's my pick of the top things to do.
Museum visits are generally for rainy days. Problem is, there aren’t that many rainy days on the Costa Blanca. So visiting the archaeology museum in Alicante (MARQ) generally means sacrificing some sunshine. But it is worth it.
Santa Pola lighthouse has some of the finest clifftop views on the entire Costa Blanca. And if you're lucky, you could get a free air display thrown in.
