Quite safe to travel to Manila.
Makati, Bonifacio Global City, Ortigas, Alabang, are generally safe and provide a forward operating base from which to spring to Manila, Pasay, Quezon City, etc.
Like many large cities the world over, there are dangerous areas you should avoid, unless your tastes lie in that direction.
When traveling around the city, here are some tips you could look into.
1. Travel with a native of the city, or someone who is familiar with it.
When I traveled to Singapore two years ago, I explored the city all by myself and did not hesitate to do so because of the city’s reputation of being safe. It is a different scenario in the Manila, though. It would be ideal to go around with someone who knows the area or knows the whereabouts as so to avoid being tricked or lost.
2. Avoid overcrowded places.
If you stay long enough in the city, you will probably realize that it is almost impossible to avoid this second tip since the city itself is overpopulated. But there are places where it is less crowded than others.
Thieves thrive in areas where it is difficult to maneuver and doing robbery could be imperceptible. There are times when you have no choice but to take public transport like the MRT/LRT and public buses, so I advise that you be keen on your surroundings.
3. Displaying valuables in public is a “must not.”
If you like taking pictures using your iPhone or SLR camera, you must be careful in doing so especially in crowded places. If you want to take pictures in crowded places, make sure that you are with somebody else who can watch over you or you might end up weaving through an unorganized crowd chasing a juvenile who took your items.
Costly jewelry such as earrings and necklaces as well as money are eye-catchers for thieves as well, especially if you’re on board a public jeepney without windows.
4. Keep your bag intact.
Even if you’re valuables are hidden from public view, it does not mean that it is already safe. Keep your cautious behavior in crowded places because some crooks have modus operandi where they slash your bags open from the sides with a knife or blade, then taking your stuff inside. A secret pocket inside your bags would be a good place to hide your IDs, money and passport.
Manila is an awesome place. I would suggest you visit Intramuros, our famous walled city and Fort Bonifacio which are an iconic places in our country’s history.
