I went by motorbike.
The road has improved much, that travelling by car is not the only method.
Very scenic drive to get there and another interesting ride up the mountain.
The reclining buddha, temples and monks make for a interesting visit. The 1000 lingas and if you walk a little further the "quick sand" pit is quite impressive.
The walk down to the base of the waterfall is a little dodgy and not for everyone, but well worth a swim underneath the falls.
