Gravity Hill,

5365 Sonoma Mountain Road, Petaluma, California 94954, United States

"Bogus. Lovely country. No anomalies. Do NOT attempt to go over the hill to the next valley"

"Quite a cool little optical illusion. My first gravity hill and definitely fun if you stop your car and put it in neutral and feel it roll in the direction opposite to what your mind tells you it should. Had to take a little detour as I was traveling on Hwy 101 but worth it for this and the nice valley views. In the photos I posted, see how that section of road woth the car on it that looks like it's going uphill? It's actually downhill."

"It’s amazing - the car rolled uphill just like the guides said it would! Looks like by all the no parking signs that the locals are sick of all of the visitors, so probably don’t get out and walk around. Beautiful views and drive, though, but if you are expecting more than a country road, you’ll be disappointed."

"Read about it online and decided to check it out with the kids. They had a blast! I had to drive around a bit and keep checking by putting my car in neutral, but I was amazed when I found the place. There is nothing else out here, and not a lot of cars. Definitely don't raise your expectations too high."

"its a beautiful drive, there's no where to pull over on the side of the road which made it annoying, surprisingly there were what seemed like a lot of cars driving out there in the middle of nowhere. Would have liked to pull over and assessed the situation. Thank God for a reviewers photos or we wouldn't have known where to start or finish. We spent 10 minutes then left. Wasn't too exciting. It didn't seem very impressive like some of the other gravity manipulated places in the western United States. But it was worth going since I'd never been. I recommend going at least to check it out, if not to just inspire your minds. Its trippy."
