Ban Ta Klang
The Suai village of Ban Ta Klang is a bit of a mixed bag: it's the best place to see Surin's elephants outside festival time, but if you are sensitive to animal welfare you may find some of it unpleasant. You can see elephants throughout the village, where people and pachyderms live side by side, but the main attraction is the Elephant Study Centre.
Khao Phra Wihan National Park
The main attraction of the 130-sq-km Khao Phra Wihan National Park is one of the region's great Angkor-period monuments. Unfortunately Khao Phra Wihan ('Preah Vihear' in Khmer), which used to sit on the Thai side of the border, now comes under Cambodian rule, due largely to a campaign by the Cambodian government to make it a World Heritage site.
