Not quite a beach but a rare geological formation located next to the sea. The waters of the lake are fed with saltwater via underground currents, through the mountain (although there is still some mystery about how this occurs). Near the sun-beds the water is quite shallow although at the opposite end they sink to unknown depths. In the lake the waters are often slightly warmer than in the sea, so it is particularly popular earlier in the season. Generally peaceful and quiet, it is a good option if you want easy access to plenty of amenities without the thump of a nearby beach-bar.
The facilities of the lake include the all-day bar, restaurant, changing rooms, showers and full wheelchair access. It is also worth staying for a drink in the evening when the rock walls are lit up and soft music floats out over the still waters.
