When going on an adventure with kids always triple check the weather forecast and therefore take enough water and never underestimate the whinging power and stubborn nature of the middle child.
On a peninsular overlooking Calabash Bay stands the tall imposing stone ruins of what appears to be a castle. It is referred to as "the ruins" or "the haunted house". In the 1890s, 40 acres of land was purchased by John Fretus, the owner of the Sans Souci Hotel. When the license was removed they decided to demolish the hotel and move the stone to Calabash Bay by a coastal steamer. They carried the stone blocks up to the ridge top and built the castle, which was completed around 1900. The plan was to operate it as a hotel/guest house because a road was partly surveyed from Berowra Railway Station to the creek. A ferry service would link it to Berrilee and beyond. However, the surveyor at the time made a terrible blunder with his survey as he did not cover the whole route personally through the rough terrain but relied on local's information for the survey. It turned out that there was a deep gully behind the last hairpin bend and the magnificent Fretus Hotel was left with no road access. It was used as drying-out place for alcoholics but in other years it was used for "booze-up" weekends. The Fretus family established an orchard, hence all the terracing still to be seen. Fretus made the mistake of introducing Angora goats which went wild and ringbarked all the orchard trees during a drought. The castle was burnt out in a bushfire some time later.

The weather forecast predicted showers and we'd planned to ride bikes with the boys, out along the fire trail to the castle. We didn't have the 45 degree heat of the previous weekend, however, there was no sign of rain and by mid morning it was heating up. I'd decided to run rather than ride, however, the run turned into walk when middle child decided it was too bumpy to ride, and when he decides he's not going to do something...
So apart from the non stop verbal encouragement to middle child to keep going the first couple of kilometres along the fire trail were quite easy and flat, taking us through the typical woodland and scrub vegetation associated with Hawkesbury Sandstone. Scott and his friend had gone off ahead and we found them at the top of a very steep hill. Too steep to ride or even drive down, however someone had tried (in a small car) and failed, some time ago. The steep hill marks about halfway along the trail and we left the bikes here and walked the next two kilometres.
As the water came into view through the trees we had almost reached the castle ruins and we were all excited to find more than just stone foundations. The partially rendered sandstone walls still resembled rooms and we could work out which rooms could have once been the kitchen, dining room, store rooms and the many bedrooms which would have once had spectacular views of Calabash Bay and beyond. Almost one hundred years of engraved graffiti adorned the walls, enriching the history of the place. In it's day it would have been a grand hotel in the bush, but really, it was a bit out of the way and with no road access, how was it ever going to survive?
We identified a few flat bits of ground to pitch tents if we planned on returning, however, all water would need to be carried the 4km in, and the name 'the haunted house' may have us thinking twice.
