If you are staying at a local resort the likes of the famous Heritance Kandalama, visiting both Dambulla and Sigiriya will be a cinch. Another UNESCO World Heritage Site and possibly Sri Lanka's most iconic, Sigiriya is only 17km from Dambulla. The reserve is open from 7 am to 7 pm and makes for a dizzying climb that is thankfully well paved. You will see much on your way up to the palace in the sky including spectacular water gardens and boulder gardens, caves with inscriptions and paintings, the famous Sigiriya frescos, the Mirror Wall and finally the grand lion-like entrance to the fortress. Spend a whole day exploring the fortress and its epic views and head down to Pidurangala next.
