Road is driveable in a very high clearance vehicle until a washout in the creek at 0.6km. Some REALLY aggressive driving MIGHT get you past this but I would be impressed, there’s sort of a workaround but it has very large rocks.
Beyond this, it’s mostly good condition driving save a few more small washouts until approx 3.5km where the road is completely gone. We took bikes until this point, but after that it’s walking only.
