There is a Burgos town in each, Ilocos Sur and Ilocos Norte. The more popular one (with Cape Bojeador, Tanap-Avis Falls, Kaangrian Falls) is in the north along the main highway. It is right after Pasuquin and before Bangui if you come from Laoag. In Ilocos Sur, you turn right from the main highway in Sta. Maria to get to this inner town. Another Burgos town is in La Union (also in Region 1). If you go up to Baguio via Naguilian road from Bauang, it is the town after Naguilian, Ilocos Sur and before the town of Sablan in Benguet. There could be other Burgos towns in other provinces. Hope this helps. Cheers!
