Banqiao Xindian is the only course in Taipei with permanent baskets. You'll likely need a guide to find the tees as they are unmarked. The locals are there every weekend, are exceptionally friendly, and will gladly guide you around. Course is mostly wide open and very long, with several extremely low ceiling shots with dangling banyan air roots.

The closest MRT station is Xinpu on the Blue line. Walk north towards the river on Minsheng Rd (approx 1.5km) until you reach the embankment and walk up and over the scooter ramp. From there you should see a large circular wooden platform along with a number of baskets. I've provided coordinates for the first tee.
