This is the best for me, I have never had it enough to walk along the Punggol Waterway in Singapore. Why the best because it’s man made but they designed it as natural as possible, from the line instead of making it straight they make it twisted just like natural river, then the river bank they don’t cement it but they plant grass and many kinds of plants, so adorable. This river pass through flats, Food courts, markets, schools, polyclinic, rest area, club house and even Malls by going through all of them allow you to feel the localness, wow right so next time you go to Singapore spend some times to enjoy this experience. Very easy you take MRT North east Line and you go all the way to one end of this line Punggol station from there you just go to Waterway Point, behind the mall you can start you journey to go around Punggol Waterway. 

Bon voyage
