To tell you the truth. I thought all of the mountain trails in Emigration Canyon were closed to the public. I was happy to discover that a branch of Killyon Canyon was open.
A group named Utah Open Lands is currently in a campaign to buy the private land in Killyon Canyon with the aim of making it open public lands.
I am not sure why land has to be owned by the state to be "open." There are plently of places owned by the government which are closed to the public and places that are privately owned that allow public access.
The rolling hills of Killyon made me think the location would be ideal for a cross country skiing lodge.
There is only about 4 parking spaces at the trail head. There is some additional parking a few hundred yards down the canyon. There is a private property sign on the road above Killyon. I am not sure if it applies to the road or the land alongside the road.
I am not sure about the status of dogs in the canyon. There is a box containing dog bags and a stinky garbage can at the base of the trail. The county has been systematically closing all public lands in the County to dogs.
