In the Philippines, the cheapest way to get around is by jeepney. These are super colorful minibuses that started popping up everywhere after the Americans left and left behind a bunch of military jeeps that got converted to carry passengers (plus there was something similar but way less common before World War II here too).

13 pesos (~0.2€‎) and you're good to go. Exit's in the back, no doors, usually no windows either (but there's a curtain for when it rains). The weather's usually decent for it. Locals say there are basically 2 types of weather here: either sunshine or rain.

The only tricky part is figuring out if it's actually going where you need it to go. There are no route numbers, usually just the starting and ending stations written on it. And those aren't exactly huge either.
