Sigiriya or Ella — which should I visit first?
Most routes visit Sigiriya first as part of the Cultural Triangle, then continue to Ella in the hill country — see SKY's real 3-day tour for this exact sequence.

The Cultural Triangle's best-known landmark compared with hill country's hiking town — most itineraries actually include both.

Cultural Triangle site centered on the Sigiriya Rock Fortress, with Dambulla Cave Temple and Pidurangala nearby.
Hill country town known for Nine Arch Bridge, Little Adam's Peak, tea views, and waterfalls.

Sigiriya — the Rock Fortress and Dambulla Cave Temple are genuine ancient sites.
Ella — Little Adam's Peak and nearby viewpoints are the main draw.
Sigiriya usually comes earlier in a Cultural-Triangle-first route; Ella usually follows as the hill country stop.
