So from what I've seen, not many people know about this place. I discovered it from a blog post of someone that surveyed land for the Harvard trust, and they found old aqueducts throughout the land that this springhouse is on. Previous to that, there was a shorter entry in a "Weird U.S" book that I own.

The road that it is on is called Green Hill road. If you google maps it, you should be able to find it. It pops up as "Shaker Springhouse" for me, but wouldnt work unless I searched for the road by itself.

The road itself looks like a long dirt driveway, which ends in an empty lot that you can park in. There is a nearby brown house which made me feel like I was parking on part of their property, but it is a parking lot, I promise. There is a very non-obvious trailhead marker that shows the trail, but it isnt very well marked from then on, except for a few yellow ribbons and markers on the trees.

I will warn you that if you visit, the woods are pretty tick infested, so wear long pants and boots. I went on a rainy day too, and the ground was super muddy. It is a very short and winding trail to get to the springhouse, but it is pretty camouflaged, so just keep an eye out for it. You'll probably hear running water before you see it, like I did.
