The dam is a great place for the kids and adults, BUT, if you want a relaxing weekend, probably not the place to go, it can get pretty busy with trail bikes, not so much 4WDs as they tend to go down to Wattle flat over at Mintbush trail.
Charlyong crossing is a bit further down the Braidwood Rd, ABOUT 9K past Nerriga, you turn right at Corang Post Office Rd about a K down the road as you cross the creek you turn into the area where you camp, not a bad spot, no facilities though, but nice and clean and not too crowded.
