I believe that the minimum fare is 10 pesos per person. It all depends how far around town that you need to go! If you are going to be around the downtown section of Tuguegarao, then, I believe, 10p – 20p is a fair price. I lived for a while in Carig Sur, which is about 3km from downtown Tuguegarao. The tricycle price for 2 people was always about 50p (25p per person). When in doubt about the fare as the tricycle driver beforehand!
