The Promenade in Castell de Ferro is a really fantastic place to take either a leisurely stroll or a brisk walk. It stretches some 2 miles in length, which can either be extended to 3 miles if you move off the promenade onto the beach. The beach here is mainly pebbles, however in some stretches on the west side of the beach, sand can be found.
 
This is still a very traditional village on the coast and remains largely Spanish speaking and untouched by tourism. Nightlife is low profile and mainly centers around the bars and restaurants, however in the summer there are a number of disco's (but these are within walking distance and away from the maddening crowds).
Should you decide to visit Castell de Ferro, there are only 2 main places to stay (other than by accommodation in apartments). Excellent accommodation can be found at the Costa Sol Hostal in the main square or out of the village on the main N340 road there is a hotel with a swimming pool.
This is both a good relaxing place to visit and an excellent base for moving around the Costa Tropical, or further up the Coast to the Costa Almeria.
