Plage de Legzira IV, Morocco, 20150923
So this is Plage de Legzira. You can get there via the R104 between Sidi Ifni and Mirleft and take the Route de Legzira. After a few hundred meters the road stops and you have to take a very steep gravel road down towards the beach. Free parking. A couple of restaurants and hotels can be found here. Walk down to the beach and on the beach, take a left and walk for another 20 min and you'll reach the 1st arc. The 2nd arc is an additional 10 min walk.
I was there mid September and it was very hot, a little windy and the sea was rough with pretty high waves.
