You can rent bikes or cycles on Hippie island and get to the Sanapur village. There are local buses that pass through this village as well. Once in the village, ask for directions to the waterfall(water flow is very low during summers). It is close to the bus stop, you could walk as well. The waterfall and the diving spot are in the opposite direction to Sanapur lake on the Reservoir road. Check the map below for reference.
