Tagaytay secures its place on most Philippines itineraries with its location above Taal Volcano's active crater. Views of the crater lake and a refreshingly cool climate make the town an enticing destination—not to mention the famously unfinished People's Park in the Sky.

The Singapore cityscape looks like it was ripped from the pages of a science fiction comic book. If you’re hungry for a true Singapore experience, sample the myriad street foods or take a cultural cooking class. The Botanic Gardens and the Gardens By the Bay offer a slice of horticultural heaven, and the observation deck of the Sands SkyPark makes you feel like you’re high above the clouds. The banks and walkways along the Singapore River bustle with local activity.
