If you want an unplug from the outside world, returning to the sounds of nature and long days where the light shifts naturally across the hours leaving you tired and ready for sleep by early evening, this is the place for you. Located right on the water, and accessible only by boat, the handful of neighbours will be likeminded.
For a bit of adventure, I loaded up my kayak paddled to the cottage from Berowra Waters (~11 km). My car was safe and sound when I returned. The cottage has a small beach which is visible (or only shallow water) for the lower half of the tides, although at full low it is probably still best to use the pontoon as there is a fair bit of silt (deep mud) at the extreme low. This also points to the sheltered nature of the creek - silt only builds up where the water is still enough.
If you have time, take a paddle down the Marramarra Creek. I must have seen 10 or more kingfishers in the middle of the day!
