The surfs flows endlessly onto the beach Reynisfjara. The volcanic sand is quite loose, and you do sink in a bit at times.
Therefore it can be a risk to go too close to the surfs, as you may not be able to return in time.
The swells here are quite unpredictable, and out of the blue some monsters suddenly arise, flowing far longer onto the shore
than the average swell does. Don't stand too far out when that happens! People has drowned here,
being sucked into the cold northern Atlantic for ever...
