Yesterday was sunday and construction works at Punggol Waterway had stopped for the day. Good for the workers.
There was quite a crowd in the evening either walking, jogging or cycling along the tracks. Small cranes laid at several corners and some sections were wet and muddy with a thin platform for people to cross over. I only cycled along the west side heading to Punggol Reservoir as I wanted to catch the sunset instead of sunrise. Sunset was around 6.50pm. When I left, it was dark and there was no lights.
So bring a torchlight along if you are coming here in the evening. Have fun exploring!
