Goulburn to Nowra towing caravan via Nerriga v/s Kangaroo Valley.

Kangaroo valley is more picturesque but involves 3 steep (5km) inclines 2 down, 1 up to traverse. There is a van park at Kangaroo valley or camping at bendeela.
Nerriga rd via windellima is less picturesque, but only has 1 short (1km) up and 1 short down, so is alot easier a drive. There is some free river camping at charleyong if you chose to drive via Braidwood.
Road conditions goulb to Nowra via nerriga are alot better these days, there is a new bridge over the shoalhaven at oallens crossing, and a new bridge over the mongarlow river too, so the nerriga road is a blacktop highway now.

I don't have any preference when it comes to choosing which to use. You will get a much straighter run via Kangaroo Valley. However, I don't mind the hills through the valley. I would suggest you use the Nerriga road as it is new country to you.

As an aside, I started using the Nerriga road 50 years ago as it was the fastest trip when running solo from Jervis Bay to Canberra. It was a good gravel road back then but I did not tow over that route because the road was narrow and because of the gravel surface. However, since then the road has been widened and sealed right through. That route is now my favoured route with a caravan.

I have done this many times towing a 19ft zone and it is an easy and pretty drive much easier than kangaroo valley as you don’t have to wind down off the off the mountain you just have to be aware of a low bridge just out of Goulburn there are a lot a/c units on the side of the road under the bridge, go the alternative route have a great trip you will enjoy way

Cambrewarra Mtn road is single lane with stop/go lights at 10 min intervals for the foreseeable future.Nerriga to Goulburn has some bad sections since the heavy rains in the last year, Ok if driving to conditions, we use this route regularly towing a 2.8t caravan.
