Spelga Dam is located about a 10 mile drive from Newcastle. It is a man made dam built in 1960. It is noted for it's ability to make cars roll up the hill. Just in front of the dam is a small in road only about 30m long that when people park their cars, turn off the engine, take it out of gear and release the handbrake the car appears to very slowly roll up the hill. ( having heard of it and being sceptical, i was very impresses when shown. )
