cross country skiing
This is one of my favorite places to go cross country skiing in the winter, and I decided to take my kids on the trail in the summer. It's absolutely beautiful in any season but it is a very different experience in the summer. In the winter it's isolated -maybe you'll run into one or two other skiers/snowshoers. In the summer there are cars and motorbikes on the road, which is a little annoying but understandable since it is, in fact, a road. I would definitely recommend this as a fun hike to do with kids -the abandoned mine/ cabin are really cool and the road makes it easy to walk. But if you are looking to really be in the woods, away from it all, I'd pick a different option (at least in the summer).
Went a few weeks ago, the snow was about 3 ft deep, but the snow in the trail was so compacted you can easily do this hike without ice cleats or snow shoes. Beautiful beautiful scenery, looked like a winter wonderland!
