The Complejo Turístico Municipal Costa Martiánez, also known as Lago Martiánez, stands as one of Puerto de la Cruz's most iconic architectural gems. Designed by renowned Lanzarote artist César Manrique, this impressive 46,000-square-meter complex features a stunning 15,000-square-meter artificial seawater lake surrounded by various pools, offering a unique Atlantic Ocean experience.

Beyond its spectacular aquatic facilities, the complex boasts restaurants, bars, and even a casino below sea level, making it the perfect spot to spend a full day soaking up the Canarian sun. The seamless blend of nature and architecture is remarkable, showcasing Manrique's unmistakable style that incorporates volcanic elements and open spaces. While some areas could use refreshing, the sensory experience and relaxed atmosphere make Costa Martiánez a beloved destination for both locals and visitors seeking something beyond the typical beach day.
