Anyone know the land use classification for Ranche Rd, Cochrane Ranche to Big Hill Springs

A couple summers ago I attempted to hike from the Cochrane Ranche to big hill springs following the Big Hill creek as it is all connected by one valley and from what I had heared it didn't cross any private land and used to be a wonderful hike. When I was about 1/3 of the way there my path was blocked by what looked like a very poorly made fence and someones trailer parked down in the valley. From what I've found in county records and maps this isn't private land and is an official road on Rocky View county maps. I've had similar issues before where I've tried to use a public through way and it has been blocked by a nearby private land owner (On a similar occasion I called the county office and they also said that it was a public through way that shouldn't be blocked off, different location though). I was wondering if anyone else had any info on what the legalities with hopping this fence might be? Obviously I don't want to trespass which is why I'm asking if anyone else knows anything about it but if it really is public land I should just be able to walk through without any issues? Also who puts up a fence on land they don't even own?
