This will take you part way to the east end of Little Lake Manitou, south side.
You are looking for a tubular micro. All weather roads although the final leg will probably not be maintained during winter months. There is currently only one road to this cache and that is from the south. The provincial highway west of this cache, and east of this cache is under water. The causeway that you might see on a google map is long gone due to high lake levels. You can't even see it anymore.
July 25, 2016. I had no issue in driving around the northern most barricade, by going through the ditch. Or one could park there and do a 5 minute walk to the cache site.
