I don’t recall seeing any Pertamina, so fill up in the Malaysian side with premium fuel.
This route is effectively signposted and is pretty easy. Turn left at Sosok, and right before Tayam.
Road from the Tayam turn is mostly OK and has some fun curves towards Pontianak. However the first half has some nasty patches of mud.
I saw three trucks bogged up to the axles.
I was bordering on panic at the first bog hole because all the oncoming trucks had left only enough space for a scooter to pass. This is common. An Adv bike with luggage is a lot wider than a scooter! And this on mud – centimetres of clearance.
Lucky this mud is not the slippery greasy kind, but there’s no way to know until you are on it.
Traffic crossing the bridge at Pontianak is very heavy. And don’t think you can weasel through it – every centimeter has already been occupied by a scooter.
If possible travel into the city in the afternoon and out in the morning, it will make a big difference. But watch out for impatient 4WDs and trucks trying to drive in the wrong side.
