The Gap is basically the mouth of Sydney Harbour with its sandstone cliffs on both sides and spectacular views of Tasman Sea, the city and surrounding bays. The area was used in Mission Impossible II. Remember that scene when Tom Cruise was climbing a cliff? That’s what I’m talking about. Every time we have visitors staying with us, we take them to The Gap. Hoping to spot a southern right whale or a humpback whale one day as the coastal waters around The Gap are a migration route for these majestic animals.
