I've been through the Bungles on a push bike - so that's a thing, but yeah, Cape Peron would be a hard slog without a boat or vehicle that can push across deep sand - water would be a tough carry.

> without the right vehicle

A loong time ago (late 1970s) I got to traverse the horizontal falls a couple of time in a home made sea kayak after being dropped off "nearby" (and later picked up again) by an old pearling lugger .. pretty low carbon effort that one, just a lot of paddling (and fishing, and digging for fresh water, and dodging the odd shark and salty croc).

Nice, I have great respect but also a level of “WTF” when encountering cyclists in the deep wilds, especially in the heat!

Passed an old guy on a pushbike with a trailer on the nullabor in 2010 and just thought “wow, that’s commitment”
