Greenfield, Massachusetts: Gravity Hill

If you are heading west, stop your car before you get to the bridge. There should be a yellow mark in the center of the road (the bridge will be about 150 ft. in front of you). Put your car in neutral and it will roll uphill backwards, all the way up the hill! So cool. Watch for traffic and don't get discouraged it took us a few times to find the exact location to stop the car!

I did not see any markers. I came on my motorcycle and sat in neutral but did not go up hill.

At first we passed it, then I found the white metal rod and parked next to it. We put the car in neutral and went forwards maybe about 50 feet. It went very slowly, though. Then we turned around and went backwards up the hill.

My grandson had heard of this so we went to try it out. It was really amazing. Your head is telling you it shouldn't be, but your car is rolling up the hill! Next time I plan on bringing a compass, to see if it has any effect, and plug in the GPS to see if it affects coordinates. It was fun. Worth the trip.

Holy cow, this is amazing! I had read about this place here, but then I saw there is also a Geocache hidden nearby, so we had to visit. We first approached from the East (heading West), put the car in neutral, and then started coasting backwards, up the hill. We then drove forward, under the bridge, turned around, stopped, and put it in neutral again just after the passed back under the bridge (heading East, this time).

The car started rolling, slowly, at first, and then it was going faster as we coasted up the hill. I think we reached a top speed of maybe 12 MPH. We continued to coast after cresting the hill and just kept rolling down the road. We stopped, went back, and tried it again, this time about 50 feet East of the bridge. We rolled, but much slower this time, but the car still went up the hill. We have no idea how it works, but it does.
