I was born here, in the south—Zamboanga del Sur, Mindanao. It’s a Muslim province, not recommended for tourists due to frequent kidnappings.
I’ve been back only once, in 1984, and stayed in the north where my father’s family is from, Baguio City. Cooler temperatures, in the mountainous region. Famous for the rice terraces, one of the wonders of the world.
My mother’s family is from the Visayas, the lowlands, with extremely hot and humid temperatures.
The Philippines has the largest Christian population in Southeast Asia. Because of its 400-year history of colonisation by Spain, I liken the culture more to that of a country like Mexico rather than an Asian country.
Many people speak English fluently, but it is not a popular tourist destination due to its political instability and the notoriety of Muslim insurgencies in the south. Not to mention the abject poverty and crime in the largest cities, particularly Manila, which is unfortunately where tourists will form their first impressions. The country does not have a tourist-friendly infrastructure when compared to Thailand, for instance.
That should not discourage people to visit; rather, in some respects it’s more reason to see the country for yourself—just stay away from the south and get out of the cities for a safer and fuller experience. You’ll need to do a fair amount of research, but that also holds true for places like India. If you’re an informed traveller, you will be fine.
