Depending on how fast you ride it shouldn’t take more than about 50 minutes tops from the Kuandu side of the bridge. It’s a little funky at the bridge turnoff and you’ll need to look carefully, as the motorcycle lane goes through a little tunnel first. Once you go through the tunnel, stay to your right (but not all the way) and the onramp for the bridge goes off to your right on a nice 270 degree sweeper. Once over the bridge, get off on the right hand side.
There are two spots in Baling where you’ll need to turn. The first is pretty obvious, the road will split, and you’ll take the left fork (It’s the larger turnoff of the two/4 lane highway). The second is not so obvious. You’ll go through a newer, more built up section of Bali, and after about 8 lights you’ll need to take a right, go down about 100yards only and hang a left. I believe there are signs, and if not the majority of traffic will make that turn. If you get lost in there, just ask for directions to the water park. If you miss this turn, you’ll be heading up the back side of Guanyin mountain.
Once you are on the 15, you’ll be on the coast within five minutes. It’s a nice 4 lane highway and will take you all the way into Taoyuan County. Look to spend about 20 minutes on this section…This will take you all the way into Chuwei. Highway 15 bypasses Chuwei and this is where you’ll need to turn. You’ll see the 15 go off to the right…Don’t follow it! About 150 yards past where it takes off to the right, you’ll come to a sizable intersection. If you go straight, the road narrows down to two lanes…Turn left here.
Now you’ll be heading for the airport… I believe it’s about 2-3km down the road to the turnoff into the cargo area. The right hand turn you’ll need to make is about a 140 degree one with a separate turn lane…Can’t miss it. From there, you are on your own as I’ve never done the scooter airport drop. But if you continue on this access road, it will go off to the left, and the cargo areas (potential parking) will be on your right.
Important…Do not go past the underpass on your scooter! You’ll end up in the main departure area, and they take a very dim view of scooters there.
I can do Teinmou-Yangmei by motorcycle using the coastal highway in about 1hour and twenty minutes…Averaging 80-100kph. I would think on a scooter from the Kuandu bridge to CKS should take 50 minutes to 1 hour.
Interesting you should compare this road to the baja…When I first got here, it was a super narrow, windy, sand dune blown section of road. One night coming back from Chuwei, a sand dune had entirely covered the road (daily occurance back then…The military spent more time fighting sand there then looking for commie boats) and I hit the damn thing at about 80kph. Be careful in the motorcycle lane near the power plant, on windy days the sand will still come up onto the highway.
