Miller Fork/Signal Mt/Donner Pass is about 17.8 miles long and located near Glen Haven, Colorado. The trail is great for hiking and normally takes a full day.
So I didn't do a whole lot of planning on this trip, but turned out overly enjoyable! I just bought a pack for my dog and wanted to break him into it before my backpacking trip next week. I started at a trailhead that I had located off of the map. There is no signage for the trailhead and is only room for maybe 3 or 4 vehicles. The Miller Fork trail is absolutely awesome! Almost like enchanted forest. The trail stays near a natural mountain stream and feeds a variety of wild mushrooms and some wild raspberries. The trail did end shortly after I had come across an old lumber mill. I made my own way up to Lookout Mt. trail and continued over to Signal Mt. which provided a nice panoramic view of the surrounding area! I decided to take Donner Pass Trail on the descent rather than cutting trail. It was a fairly long hike with plenty of wonderful views!
I would recommend just hiking Miller Fork Trail on it's own as it becomes easy to lose the trail around mile 4 and trail is nonexistent around mile 4.5. A different Trailhead may be an option for the Signal Mt. summit. Although I have nothing but great vibes about the trail I chose
Miller Fork Trail is NOT accessible to the general public via Miller Ford Rd. That road is private and there is no trailhead where the trail crosses the road. Cars parked there are an access hazard for local residents and emergency vehicles.
Access to the Miller Fork Trail is from the Dunraven Glade Rd trailhead. Visited on Feb 17, 2013
