Rising dramatically from the central plains, Sigiriya, the enigmatic rocky outcrop of Sigiriya is perhaps Sri Lanka’s single most dramatic sight. Near-vertical walls soar to a flat-topped summit that contains the ruins of an ancient civilization, thought to be once the epicenter of the short-lived kingdom of Kassapa, and there are spellbinding vistas across mist-wrapped forests in the early morning. Pidurangala Rock is a massive rock formation almost directly opposite Sigiriya. Pidurangala has an equally majestic view as the former of rolling lake-and-land vistas. Kings ruled the central plains of Sri Lanka from Polonnaruwa 800 years ago, when it was a thriving commercial and religious center. The glories of that age can be found in the archaeological treasures that still give a pretty good idea of how the city looked in its heyday.
