The Seletar Expressway (SLE) connects the central districts to the northern woodlands. It offers a scenic drive past the Upper Seletar Reservoir and is the gateway to Singapore Zoo, Night Safari, and River Wonders.
This expressway is ANDY's top pick for family zoo trips. The drive through the greenery is calming, and you'll often see the forest canopy stretching across both sides of the road.
The SLE also connects to the Woodlands Checkpoint for those driving into Malaysia - though ANDY recommends going during off-peak hours to avoid the jam!
