Located next to the Castillo de San Gabriel on the main promenade of Arrecife, Playa del Castillo is a small sandy beach in the heart of Lanzarote's capital. Its central and accessible position makes it a practical spot for those strolling through the town centre who want a quiet place to reach the sea.

The surroundings are shaped by the nearby bridge connecting to the castle, which creates an area of calmer, more sheltered water, especially in the small section beside the structure. Here the sea tends to be quieter than on the open shore. This urban beach doesn't usually attract large crowds, and its small scale gives it a more intimate, less busy character than other beaches on the island.
