I'm not sure if this is a recognized beach or just something the Dorado beach hotel created, it's not on the map but if it looks like a beach, smells like a beach....

This is a small, soft golden sand beach just in front of the Dorado Beach hotel. They may have created it but remember all beaches are for public use so feel free to try it out. The great thing about this beach is there's an ocean swimming pool in front of it. They have walled off an area a couple of times the size of an olympic pool for safe swimming, protected from the waves. 

Whilst the sunbeds are for the hotel guests there's still half the beach for towels on the sand. The promenade goes from here to Arguineguin in one direction and all the way to Anfi beach in the other. There's supermarkets, cafés and restaurants withing short walking distance so all-in all, a nice beach with good facilities on hand.
