The road up to the springs is paved some of the way but other parts are rock and loose stone then there is the 250 steps down to the spring which are even harder on the way up but a lovely scenic walk through the shade of the trees. 
We have been there many times and have seen great wildlife including butterflies and tropical birds. If you follow the river up into the Forrest after around 50 m you will come to a nice waterfall.
