if you happen to be in Manila this is one of the things you should include on your visit. I used the Grab app ( Uber in the Philippines) it was about 300PHP and you will need to pay the toll fee of 160PHP to get to the north of Metro Manila. Once you get there go and visit the Manila house and rent this amazing bamboo bikes and a tourist guide who will take you to amazing corners of Intramuros while describing the history behind this Spanish arquitecture.
