DEVKU
devkund-waterfall-a-monsoon-trek-to
The weather was astonishing amazing! we started early morning from pune and took the tamhini ghat route to reach devkund and it took around 3 hours! This was one of the crazy adventure! Hope you enjoy. If you are planning go in the end of September and Starting of October.
DevkundWaterfall is situated near the Bhira dam in the Raigad district of Maharashtra. It is undoubtedly one of the most stunning waterfalls in India. This waterfall is counted among the very few Perennial waterfalls in Maharashtra and runs throughout the year. Its natural beauty is absolutely mesmerizing !!!
The Devkund waterfall is hidden amidst a forest near Kolad. The view of white water cascading down into a clear bluish-green water pool is truly unmatched! There is hardly any waterfall where you would see such crystal clear bluish-green water. It’s hard to believe that a few years back, it was completely unexplored & unknown to the rest of the world!
The Devkund waterfall trek route leads along Bhira dam backwaters and dense Forest. It is medium in grade and also needs to cross a water stream.
