Ridi Vihara, literally the 'Silver Temple', is so named because it was here that silver ore was discovered in the 2nd century BC. Although not on the usual beaten track, it's well worth a visit to see its wonderful frescoes and the unusual Dutch tiles in the main cave.
Uda Walawe National ParkOf all Sri Lanka's national parks, this best rivals the savanna reserves of Africa, with its elephants, buffalo, sambar deer and leopards. There are 30 varieties of snake and a wealth of birdlife. You can choose a 4WD from one of the many gathered outside the gate; you'll have to pay extra for a tracker.
DimbulagalaDimbulagala, or Gunners Quoin, stands out 545m (1787ft) above the surrounding scrub. There are hundreds of caves cut out of the rock in a Buddhist hermitage that has been occupied almost continuously since the 3rd century BC. The temple at the base is the first of 15 cave temples in the complex that can be explored on the way to the dagoba at the top.
PanduwasnuwaraThe 12th century remains of the temporary capital of Parakramabahu I are nothing on the scale of Anuradhapura or Polonnaruwa, but it's worth stopping in if you're heading past, even though the sprawling site, covering 20ha (50ac) hasn't been fully excavated.
AukanaAccording to tradition the magnificent 12m (30ft) standing Aukana Buddha was sculpted during the reign of Dhatusena in the 5th century - though some sources date it to the 12th or 13th century. Aukana means 'sun-eating', and dawn, when the first rays light up the huge statue's finely-carved features, is the best time to see it.
