This cache is so close to the hwy 403 but it is not accessible from there. First of all stopping on such a highway can put you life and others lives in jeopardy. Secondly there are wetlands and a fence between the highway and the cache. If you are on the 403 and wish to get this cache or the rest in the area please exit on Garden ave. on Brantford or Hwy 52 near Ancaster.
