Rathnapura-Wewalwaththa-Balangoda road is 43km in distance and you can enjoy 13+ waterfalls in one day. This is my experience of waterfall hunting along this road. Enjoy it.
You can view following waterfalls along this road (order from Rathnapura to Balangoda)

After our Hunt on 01 May, I was yearning to do more of them as the season is ideal for it. However, there was this nagging feeling in the back of my mind about visiting Batadomba Lena as well for the past year or so. My visits to Beli Lena, Pahiyangala and Alawala Pre-Historic caves stimulated this idea more and more so decided to get two birds with one stone.

Tony managed to get permission from his Royal Highness and joined me for the 2nd leg of Tour de Waterfalls with his ever so trusted bike which is as old as him. We met around 4.30am and hit the High Level Road and were on our way merrily. However come Godagama and Tony suddenly braked hard to avoid a ghost Tuk-tuk which drove across with no lights whatsoever. The result was the headlamp of our bike came off and was hanging from the wires as a result of the brake. Just imagine how old is the bike and Tony himself. I was worried right throughout that Tony might fall apart just like the bike.
