These are the famous Farallones de Cosiguina or Cosiguina Rocks. I'm not sure that they can be visited because they are a wildlife sanctuary and the Nicaraguan government is pretty keen about keeping them unspoiled which would be impossible with the mass tourism that is becoming a reality in Nicaragua. Anyway, it would be nice if you are able to visit them. Good luck!
Impresionante toma, felicidades y cordiales saludos.
