Sera Ella is located from 18km's down from the riverstone moutain. Its better if you use a jeep or a van with increased weel hight to watch this place. The name "SERA ELLA" explains that the beauty of this waterfall is just like the leaves of a sera tree hanging down. Its HIGHLY not recommended to bathe in this waterfall because after a curtain point it directly goes deep without a measurable point.
Another beauty of this waterfall is that there is a small cave behind the waterfall, now a days its well prepared to protection of the viewers so that everybody can come and watch it easily.
Sera ella is an amazing wonder if you want to explore the natural nature of the srilanka, The time we visited, This beauty was little less with her load of water but right after the rainy season shes ready to shine as a newly born girl. please conserve this beauty for the future generation, and be very very carefull when you're visiting this place.
