You go to the Gaisano Grand Mall in Talamban and take a motorbike up to Budlaan and from there it's a 45 minute hike to the start of the river (Just tell the drivers you are going to the waterfall and they know where to go).
The trail there is marked but can be a bit hard to follow.. so good luck with it :)

And thanks, we are very delightful indeed hehe
