Designed for beginning, intermediate and advanced snorkelers, this exclusive three-hour excursion begins with a visit to the Diving and Snorkeling School Center in La Manga del Mar Menor, a 13-mile long spit that separates the Mediterranean Sea from the Mar Menor lagoon. Once you arrive, an experienced PADI guide will offer safety instructions in the use of your equipment and share his knowledge of the seagrass species called poseidonia alga, which plays an important part in the area's ecosystem. Then, you'll don your gear, follow your instructor to the perfect spot and dive right in. Along with the sea grass you'll swim among the colorful critters such as startfishes, Symphodus Tinca, among others. When your exciting venture comes to an end, you'll travel back to the pier.
