An interesting glen from the point of view that you can have a walk of whatever distance you want.   If you drive up the glen you will eventually arrive at a lodge where the tarred road ends.   There is an old cottage on the left and, if you turn in front of it you will see another, derelict, cottage on your right.   I was told, many years ago, by the head gamekeeper,  to park at the gable end of this cottage, but it might be wise to contact him personally if you wish to walk on this estate.   Again this is not a particularly interesting glen apart from the Glenogil reservoir which is full of wildlife and a beautiful spot on a nice day.
