One of our side trips in Kerala was to Athirapilly Falls. It is a 30m (100ft) high waterfall in the foothills of the Western Ghats. It if fabulously gorgeous there; with the waterfall tucked in between hills covered with lush rain forest.
This place is not on the usual list of must see places for western tourists, but it is popular with domestic tourists. Despite the backdrop, it is not so much a nature experience as a social experience. Welcome to Indian mass domestic tourism.
