Our family, kdkk17, Marmalang (bigger family, bigger name. Everybody gets billing here), and myself, have each planted a cache in the Louth Conservation Area. One is on the Bruce Trail and the others can be accessed from the Louth Side Trail.
Find parking at N 43' 07.308, W 79' 21.067.
My cache is located about 25 metres from a trail that bisects the Louth Side trail, so light bushwhacking is required.
You will also find "Bruce Trail or Land of the Lost?" by devilpanda (GCGW1V) nearby in the Louth Conservation Area if you have not logged it yet.
