This is the last of a mini-series hidden along Kiko Trail, also listed as Old Railroad Trail according to Google Maps.
While this trail is wide enough for a vehicle, I would politely suggest against it as this former railroad is now a walking trail enjoyed by the residents of Clifton and Morenci. There is ample parking along side of Copper Verde Lane and before the start of Kiko Trail where the first cache, Kiko Trail 1/3, is located.
Please bring your own pen. After finding, please cover cache better than you discovered it. Happy hunting!
