The Philippines like many other developing countries in the world is still far from comprehensively embracing accessibility and into becoming barrier free environment. Although there are already Accessibility Laws in place, implementation is sadly still lagging behind. But do not get deterred by these. Many interesting places abound and await your visit.
Manila and nearby surrounds particularly Makati, the premier financial center, as well as Taguig, Pasig and Mandaluyong, all nearby cities have sprawling new buildings and commercial complexes (which are among the best in the planet) which are highly accessible. There will surely be lots to places to wander around.
The BGC (Bonifacio Global City) which has been the subject of many blogs and videos at YouTube, is certainly a place to visit and enjoy.
