Feel the sunshine on your skin at Punta Mogotes Beach. Once you've worked on your tan, hang around and watch the sky turn kaleidoscopic as the sun begins to set.
When you've finished at this Mar del Plata stretch of coastline, why not check out Colon Square, Bristol Beach, and Torreon del Monje? They're not very far from Punta Mogotes Beach and also a hit with many tourists.
