Inland about 35 kms from Tumby Bay SA is the lovely little town of Cummins. This town has a wide range of facilities, ranging from an IGA supermarket, a butchers, takeaway, a hardware store, a mechanical workshop, hairdresser, bakery (oh what a bakery!) and a great caravan park.
It is fairly small (I think only about 10 or so powered sites) but heaps of room for unpowered sites. Some of the sites are on lovely fresh green grass, even at this time of year at end of Summer. And I think the washing machine is free, but don’t quote me on that.
Pay for six nights and stay seven, at $25 a night for a powered site. A tip...#8 is the best spot. Which we are on!
