For this 3-in-1 ride, you can start anywhere along the loop but one potential way to ride this route is to break it up into two loops. You can park in the carpark at Bukit Batok Nature Park and go north or south. I have the instructions beginning at Buona Vista MRT/StarVista because I like the cadence of the ride this way — the warm-up of the Green Corridor and neighborhood before hitting the hills.
Check out a beautiful garden, trek to Nanyang Technical University and all its cool building and return along sidewalks and PCNs.
A wonderful ride for children with postcard views and play areas and manageable distances.
