so banaue is in ifugao? or ifugao is in banaue? i am not sure.
you can trek to this falls between an hour to three hours, depending on how fast you go, but just a friendly warning, it is a long way, you will hike up and down and in the middle of rice terraces (with a magnificent view of the area) and when you get there you would wish you won't have to take the same route again going back :P bring as much drinking water as you can carry :D
on our way to the falls many locals walk past us like they are just walking five meters instead of five kilometers, some were bringing cases of beer, or sacks of grain, and surely they are laughing at us secretly after looking at our faces covered with sweat and red from the heat.
usually when i do some grueling physical activity, i get the body ache a day after, but trekking to the tappia falls was a different experience, my body could not wait for the next day to start aching.
all effort is graciously rewarded of course when you get to the falls and the sites. you get to see a part of the philippines that most of us filipinos only get to see in pictures in school.
you do not really need a guide to get to the falls, just follow many tourists on the trail, you will not get lost, the local government does not require tourists to register or have a guide unlike in sagada.
