If you are doing a day tour of Siquijor, it will be part of a day tour. If you have a map and your own transport, it will not be particularly hard to find. It is not far out of Lazi. There is no actual carpark. You jut pull off to the side of the road. It costs something P25 to park. There is a sign saying you are at the falls. It also says the parking fee. There are no fees to access the falls. From where you park, there are about 140 steps down to the falls. Where the stairs come out is not one end of the falls or the other. The falls are on multiple levels. At the bottom of the stairs, there are several levels to the left going up and several levels to the right going down. I didn't know about a cave until I read a review today. So for little gems like that, it will be worthwhile having a local guide, otherwise, no guide needed.
