The Rockland Tunnel is a part of the bike trail, so you can bring a bike and travel through the tunnel if you wish. Otherwise, you may walk through the tunnel. If you are afraid of walking in darkness, you should bring a flashlight with you. There is a point in the tunnel where you will be unable to see any light. If you don't mind walking in the darkness or if you prefer the excitement of walking in the darkness, then you should try it! I think it is more fun to go through the tunnel without a flashlight!
Freedom Falls is one of Rockland's waterfalls. If the water is not flowing too strongly, you can actually walk on the rocks just atop the waterfall! You can also walk on the stones below the falls. There are some large rocks nearby where many people like to eat or just sit and enjoy the waterfall!
This particular iron furnace was built in 1832 and stopped producing iron in 1854. The furnace was powered by a waterwheel. The mill race (a manmade channel for the water to travel to the furnace) is still intact, and is considered to be one of the best left standing. Actually, many consider the entire furnace to be one of the best preserved iron furnaces left in the world!
You can actually climb inside the furnace to look up out of the top. It's really an interesting perspective!
Sadly, there is a bit of graffiti on the furnace, but it is still a great site!
From 322, travel to Pittsville, which is 8 miles from 322. Travel on Rockland Road until you come to Rockland Station Road. Travel on Rockland Station Road until you see a very large rock on the left side of the road. Stop here (the pull-off space is larger here, which may serve as a better marker). This rock is just above Freedom Falls, so you can walk down the slope to the falls. There are steep slopes and gradual slopes, so choose whichever you prefer. Then, travel down the slope (on the left of the road) until you come to the river. You can follow the river downstream to get to the waterfall. This may take time, and it's best to wear shoes that grip if you want to get down close to the falls, because the rocks are slippery.
Once you are at Freedom Falls, the Iron Furnace is located just below the falls. Simply walk down the path to get there.
To get to the tunnel, travel to the end of Rockland Station Road (this is also an indicator that you've driven too far if you are trying to get to Freedom Falls. The pull-off for Freedom Falls is just above the end of the road).
It is best to wear old clothes or clothing that you do not mind getting dirty. Your shoes should be something that you can hike in.
Miscellaneous: If you come in the summer, you may want to wear bug spray. There are quite a few mosquitos around the water.
If you plan on biking in the tunnel, then you'll need to bring your own bike.
If you are going to walk in the tunnel, but do not want to walk in the dark, you will need to bring a flashlight.
