I just visited Miag-ao Church and it is indeed very beautiful. We went to Iloilo for the Dinagyang Festival which is held on the last weekend of January. We went to Miag-ao and loved the rod trip going there. You should not miss having lunch at Allan's (Oton) or in Doming's (Miag-ao) for their oysters and other seafood (and they're very cheap too). The Miag-ao Church was extraordinarily beautiful - with the buttresses and the intricate design of the front facade of the Church. Too bad we weren't able to enter the Church because it was closed (I don't know if it was closed because it was a Monday or if it was because we were there during lunch time).
