Gravel update.
Volcán Osorno is now paved all the way to the top, that surprised me.
The road from Puerto Varas to Volcán Osorno is mostly paved but they are undertaking some improvements so a few stretches of gravel with managed one way traffic systems.
The road from Volvá Osorno to Petrohué is completely paved
The road from Volcán Osorno to Pueto Octay is nearly completely paved, likewise where it is not paved they are doing some pretty major civil engineering and my guess is it will all be paved within 6 months. Really it is just one small corner of it remains unpaved.
Thanks for the Petrohué tip
