This is a large estate with a hunting lodge and long views over to Ben Lomond. There are many paths and trails, around the lodge the paths are fairly flat and asphalt as are the paths around the car park. There are scattered objects of interest within the grounds and extensive woodland. There is a rough hard core, steepish, track down to the River that should afford a good view of the arches of the bridge, although a different view is possible from near the lodge. There is a similar track down to the top of the bridge and a ruined castle (folly) behind this. There are other varied routes within the area that I didn’t have time or energy to check. There is a large car park within the grounds next to the playpark that is not locked. Main entry gates are not locked either. Just beyond the car park within the estate, there is a barrier that comes down at 5pm, for the road that leads from the main estate road up to the lodge, I was told that the barrier is erratic, so may not be down. This does not prevent access to the grounds around the lodge as it is accessible on foot from the main car park. This is a short steep hill, but it might be possible if necessary for anyone to slightly break the rules of the one-way system to get you to the lodge. There is parking around the lodge area. I guess a Monday night may not be that busy with vehicles.
