I've cycled there up the road, several times. It's not nearly as far as you might think. Psychologically it seemed a hell of a long way when I went for the first time, and in fact Jan gave me and bike a ride back on his boat. But the second time seemed to take no time, and cycling back (at dusk) took just over 30 minutes.

I agree, I've no desire to be on that road after dark, even with a powerful headlamp. I've twice come across a crocodile stretched across the road apparently asleep, and I've no desire to ride into one!
