Sholayar dam is around one hour from Valparai. There is nothing much to see around. It's good enough for a couple of photos. It is windy all the time, so overall a good place to spend an evening.
The Sholayar dam is a vital reservoir under the Parambikulam Aliyar Project and has a water storage capacity of 160 ft (49 m). The reservoir's overflowing waters are let into the Parambikulam Reservoir through the saddle dam. It is constructed by a team who was working under K Palanisamy, the most popular engineer in that area.
Lovely place for a picnic surrounded by hills. The roads are winding and great drive up in the hills.
