Guardamar, Urban sand beach in Guardamar del Segura, Spain

Guardamar is the town beach of Guardamar del Segura, in the province of Alicante, on the Costa Blanca. It lies at the mouth of the Segura river, beside the Mediterranean, and is made of golden sand. The beach runs along the built-up waterfront, with the town's seafront promenade and low-rise buildings close behind the sand.

Guardamar is the beach of Guardamar del Segura, at the mouth of the Segura river on the Costa Blanca. The town's seafront was reshaped in the late 20th century by the pine-lined avenues and apartment blocks of the urban centre, while the dunes north of the river mouth were protected as part of the Guardamar Dunes park, fixing the boundary between built frontage and moving sand.

The beach takes its name from the town of Guardamar del Segura, at the mouth of the Segura river in the Vega Baja del Segura district of Alicante province. Its dunes were planted with pines and palms in the early 20th century by engineer Francisco Mira Botella to stop the sand from burying the town, and the beach sits beside that wooded dune belt.

Guardamar beach runs north from the mouth of the Segura river towards the town centre, with the Paseo Marítimo and its palm-lined promenade behind the sand. Access is level from the seafront avenue, and the central stretches are the busiest in July and August. The northern end near the dunes is the quieter approach on foot.

Native dune plants and wild vegetation grow along sections of the beach, creating an unexpected natural element within the urban setting. These green spaces have survived relatively intact despite the dense residential development surrounding them.
