Diving
The Costa Blanca can be an ideal place to base your scuba diving holiday or even obtain your first qualifications.
The visibility in this part of the Mediterranean Sea is very good, especially at the locations further away from the coast like at La Llosa and the island of Benidorm. There, visibility of 20 to 40 meters approx. 65 to 130ft is quite normal. There are, of course, days with heavy seas but these are rare and there are plenty of dive sites to choose from so you should find at lease one with calm seas.
The great atmosphere and watersports attracts individuals and families alike. You can enjoy fishing, windsurfing, scuba diving, snorkelling and great seafood, or just relax on the beautiful stretches of beach. All cliffs and islands as well as the reef with the drop off at Benidorm offer attractive diving opportunities. Depending on your resort along this coast you can find underwater caves and caverns, explore recent but surprising wrecks or participate in one of the many diving courses offered by the excellent local dive centres. Underwater visibility varies with the weather conditions, usually averaging 7 to 30 metres / 26 to 98 feet but sometimes exceeding 39 metres / 130 feet. Water temperatures are quite comfortable ranging from 13° to 26° Celsius / 56° to 80° Fahrenheit. The weather on Costa Blanca in Spain permits year-round dive activities.
