There number of waterfalls and 3-4 shops in the way, so there is no need to worry about the water, you will get plentiful.
When I reached the destination- Kareri lake and watched it from my own eyes, it felt magical. No words or picture can describe that feeling, it felt almost like it wasn't real. You have to be in that place to witness the magical bliss the lake gives. Sublime Beauty.
I went all around the lake and clicked pictures from every angle I could, before my phone's battery died.
So, just witness the beauty as much as you can
