Getting there: From the intersection of Hwy 72 and Hwy 93 in Arvada. Drive west on Hwy 72 and turn right on the first road to the right called Plainview Rd. Drive for about 2.4 miles up Plainview Road and you'll see a burn area, the trail starts on a sharp 'S' curve in the middle of the burn area, 2.4 miles from Hwy 72. It's a social trail that I only happened to see when driving past and it panned out to be a great trail on a beautiful sunny day.
Specs: This is on the side of the road, no parking lot or toilet. The trail to the tracks is fairly short, it only took me about 20-30 minutes to reach the tracks and it could be hiked much faster without a baby. After reaching the tracks, we continued along the dirt road that probably is a service road for the train. We walked until the road crossed over the railroad and Magnolia was tired and fussy, so we turned around after eating some snacks.
The hike: I really didn't know if this trail would pan out when I started on it with Magnolia in the Ergo Carrier and my camelback on my back. I always feel like a pack mule these days. Initially, I had planned on hiking a trail near the intersection of 72 and Plainview Road; I always see cars in a parking lot there and there are small open space signs nearby. But when I stopped, the gate to the trail was locked with about 5 padlocks and I wasn't sure if hopping the gate with a baby was the best idea, so I got back in the car to continue down the road. There were a few other cars in the lot, I am not sure if they were hiking/biking or if they were there for another reason. If anyone has any information on the Open Space trails in that area, please post!
Anyway, the dirt road looked promising so I drove up the road and kept hoping I'd see a trail; I drove for nearly 3 miles until the road crossed the train tracks, here the road turned private and I turned around to head back down. Then I happened to see this trail as I was driving back. Since I had no-where else to go, I figured I'd hike there and even if the trail didn't pan out, I would just walk up and down the dirt road, which boasted eastern views of Hwy 93, the vast plains and windmills beyond. The trail was better than a social trail, but definitely not popular and I thought it was ending a few times, but I kept walking and would see it again.
We continued walking down the service road, stopped for a snack and then hiked back to the car. No more trains came through, thankfully, and we could see the long train in the tunnels on the side of the mountain in the distance.
