Explore Costa Blanca

The Costa Blanca (which means “White Coast” in Spanish) stretches 200km along the coastline of the Valencian Community Province of Alicante, on the southeast coast of Spain. It is a popular holiday destination for Europeans and in the summer, millions of tourists flock to the white beaches. Some of the most popular towns are Benidorm, Torrevieja and Santa Pola.

With one of the most developed diving communities in Spain, it has many dive centres, scattered within tourist hotspots. Almost all offer diving courses from introductory all the way up to professional qualifications. Dive resorts are found in some locations and liveaboards can be found in the nearby Balearics, though not directly off the Costa Blanca coast. 

With dive sites scattered along the rugged shoreline, there will be something to please everyone. There are caves, fascinating rock formations, WWI and WWII wrecks as well as exhilarating drift dives near Calpe.

    SSI Open Water Diver Course

    Diving is your thing... You know it. You've done a try dive before, or you may be snorkeling and feel like a fish in the water... You need to see this spectacle in first person and without anyone holding your hand... The SSI Open Water Diver course will prepare you to dive to a maximum depth of -18 meters, anywhere in the world, in the company of a diver with the same or higher certification. The course consists of a theoretical part, a part of learning skills in confined water (conditions similar to a swimming pool) and a part of open water dives. The theory part can be done online, including exams, so that when you come to shore, we focus only on diving. Of course, if you have any doubts about the theory, you will clarify them in Nisos Benidorm with any of the instructors. The confined water skills part we usually do in the sea, in a protected area and in shallow water, similar in conditions to a swimming pool; there you will learn to know and handle your equipment, to control your buoyancy and to solve any problems that may arise in your dives. In this part of the course we try to repeat the skills a lot, so that any problem that would arise in a real dive you will be able to solve it, since you will be familiar with it. If the sea conditions were bad we would go to the pool but we prefer to do it in the sea, since where you are going to dive in your real life will not be a pool. Finally we will do the open water dives: 4 dives in which, with your instructor, you will put into practice several of the skills learned in the previous part of the course and you will begin to enjoy this exciting activity. After completing the three parts of the course you will receive a digital certification that will enable you to dive anywhere in the world. The price of the course includes everything necessary for the development of the course: - theory kit, - additional theory classes, - diving equipment rental, - five confined water sessions - one additional confined water session at the discretion of the instructor - 4 open water dives (shore and/or boat, depending on the modality contracted), - 1 additional dive at the discretion of the instructor - insurance during the course, - certification fees WHAT IS NOT INCLUDED: Everything not included in the previous section.

    Diving in Costa Blanca

    The countless dive sites along the vast Costa Blanca offer huge diversity. Around the port of Murcia, there are many shipwrecks to explore, mostly from WWI and WWII, such as the famous El Sirio. Closer to Alicante, there are caves carved into the limestone cliff faces, which create beautiful dives, with golden sunlight filtering through the rocks.

    Near Moraira and Calpe, you can experience some thrilling drift dives. The Islas Hormigas Marine Reserve is a great place to see all of the marine life that this region has to offer, as it is protected from fishing. Most places have access to shore dives, which are perfect for beginners.

    The best Months to Dive in Costa Blanca

    Diving in the Costa Blanca is possible year round due to the warm Mediterranean climate. The high season, and the best time to dive, is from May to August. The water temperatures peak at 27°C in July and August and the days are long, hot and dry. This is the busiest time of the year though, so be aware that it will be busy!

    The winter stays relatively warm, with temperatures rarely dropping below 10°C. The water temperatures dip to 14°C in February though diving is still possible in thick wetsuits, if you’re not afraid of the cold! Some dive centres close during the winter so check before you book. 

    Top Wildlife Sightings in Costa Blanca

    Mediterranean marine life may not be as colourful as more tropical locales, but it is still beautiful and very varied. Within the reefs, you can see octopuses, cuttlefish, stingrays, moray and conger eels along with many more. Fish like scorpionfish, blennies and gobies blend into the rocky seabed, whilst wrasse, bream, damselfish flit around the rocks and enormous grouper serenely glide across the reef or hide in crevasses. The eagle eyed might spot some great macro including nudibranch, shrimp and other crustaceans.

    The rarer, but not unheard of, species include eagle rays, turtles, dolphins and whales - though the latter two are usually only seen from the surface. Summer visitors are the giant, bizarre-looking mola mola, or “sunfish”. Beware of small stinging pink jellyfish in the summer months. Hunting fish like tuna can be seen in the blue, along with huge schools of barracuda, jacks and dentex.
