The municipality of El Rosario is located in the east of Tenerife, on the south face of the mountain range that crosses the Island. With a surface area of 39.42 km2 (24.5 miles), El Rosario spans from the wetlands and forests of La Esperanza to the sunny coastal areas of Tabaiba and Radazul, which are sheltered from the wind. Its stretch of coast is 4.52 km (2.8 miles) long. El Rosario is surrounded by the municipalities of Santa Cruz de Tenerife, La Laguna, Tacoronte, La Matanza, El Sauzal and Candelaria. This is a great municipality for a quiet family holiday in a relaxed atmosphere, with the chance to enjoy the countryside and greenery on a variety of mountain trails, with several recreational areas. The area of La Esperanza, for instance, has a considerable expanse of pine trees, firetrees and tree heath. The recreational and camping area of Las Raíces can be found inside this forest and is a meeting point for tourists and locals wishing to spend some quality time in the countryside. Legend has it that it was named "La Esperanza" (meaning Hope) when the conquistadors reached its peaks and saw their camp by the coast in the distance on their return from the tough battle of La Matanza de Acentejo.
The coast of El Rosario includes the beaches of Varadero, a small pebbly beach with volcanic sand; Radazul, with its vast sunbathing area; and La Nea, with its lovely promenade with gardens and a refreshment stand-come-bar. Other popular bathing areas include Playa del Moro and Playa de Tabaiba. El Rosario also has a marina in Radazul where there are plenty of ocean sports going on, such as diving and water skiing.
El Rosario's historic heritage is dotted all around the municipality. Elements of traditional architecture can be found near to significant archaeological settlements. The threshing fields, canals and public fountains are what remains of the agricultural lifestyle that reigned in this area when the Spanish troops settled there.
