The Lakeside Rest Area off Alexandrina Drive in Yarralumla has lovely views of the lake. The area is not large so it is more suited to campervans and small motohomes rather than tow vehicles. There is a paved area just a few metres west of here which is also worth exploring. I could not find any signs prohibiting camping. There are no amenities nearby. If you decide to stay overnight then it is entirely at your own risk.
