PUJ-->Boca Chica->Bayaguana->Monte Plata->Cotui->Piedra Blanca->Villa Alta Gracia.
Will take longer, but a really interesting route.
I've ridden it on motorcycle as well as SUV. It's fine, paved except for maybe a kilometer toward Cotui, and then it top hardpacked gravel for that short stretch. It's actually a nice, pleasant ride.Yes. I've seen that route in maps. Not sure how up to date that is. Do you know how the condition of the roads are there? And how long it would take me more or less?
