I crossed it about 5 times when I was travelling around East Kalimantan (Indonesian Borneo), mostly flying though, because most of the jungle there you can’t get through by road, so it’s either planes or boats.

I’ve crossed it to get to North America, Europe, and Bangkok a few times. I don’t know if I’ve ever been on it on the actual land though.

I would have been withing about 100km of it in Borneo anyway.
