Punta Galera is about four kilometres north of San Antonio, just short of Cala Salada, and it is not a beach. It was a seaside stone quarry, and what the quarrying left is a set of flat rock terraces stepping down to the water at different heights.
People lie on the slabs and get into the sea by climbing down or jumping off them. The seabed is rock with heavy weed and a few patches of sand, and the snorkelling is good.
What is there
Nothing. No bar, no sunbeds, no showers, no toilets and no lifeguard. Water and shade have to come in with you, and everything goes out again.
Getting there

This is the difficult part. The turn is unsignposted, off the San Antonio to Santa Agnes road through a residential area, and it ends in rough parking by a white wall. From there it is a path and then a scramble over rock.
Wear something with grip. It is not suitable for small children, for anyone unsteady on their feet, or for a pushchair.
Several sources report car break-ins at the parking area. Leave nothing visible.
What it is known for

The sunset, which faces due west with nothing in the way. It is also a long-standing naturist spot, the main one in the San Antonio area, and visitors have a habit of building stacked stone cairns on the terraces.
