From Sagada we took a car overnight back to Manila, the capital of Philippines. Despite the drive being 10 hours through the mountain range, the car's brakes broke right half way through around 2AM. Driver literally took half of the car apart to fix it, in the middle of the night, somewhere up in the mountains under the stars. It took 4 hours to get the car up and running, so the journey ended up being 14 hours back.
Not sure about swimming policies right in the historical center of Manila. But according to this photo above it's quite OK. You even have time to put on goggles.
Apparently Manila's Chinatown, in the area of Binondo, is the oldest Chinatown in the world, established in 1594.
About 2 hours South of Manila there's a Taal lake which is technically a massive volcano crater filled with water. Inside the crater's lake there are smaller volcanoes that form an island called Taal Volcano island. It is the second most active volcano in the Philippines with 33 historical eruptions. The thing is that Taal volcano has also lake in it's crater with boiling water. So it's lake within a lake, like a volcano inception.
