Platja de les Marines (Dénia)

Les Marines begins where Dénia's port ends and runs several kilometres north toward Xàbia. It's fine, golden sand, wide, with a very gradual entry into the water that makes it especially easy with small children; the seabed is sandy along its whole length, without the rocks that mark the coves south of the town centre.

It holds a Blue Flag, has a lifeguard and sunbed rental in high season, and a wide promenade that rarely feels crowded despite the volume of people in summer. Because it runs so long, there's almost always a quieter stretch further from the main access points, even in August — it's worth simply walking a bit past the first entrance.
