La Jolla, California - La Jolla Gravity Hill

Tried this one with my boyfriend. You have to go with someone because only the passenger can see the [rolling uphill] effect. It does seem like you are going uphill when you are indeed going downhill. I could feel the truck driving downhill but it looked like I was going up. You may have to do this a few times to feel the effect fully. Or trade with the driver, etc. [Nichole G., 01/03/2009]

This really works! It's easy to find the pole with the three stripes. The fence for the fairway is covered with ivy or something similar. The hill is just steep enough that when you are rolling up it and look back, it seems really steep! [Alicia C., 07/18/2008]

The first thing that makes this hill interesting is that you roll forwards up the hill, not backwards like all the other hills I've tested. It looks like a dud at first glance compared to some other hills, but your vehicle will crest the hill you are rolling "up" then proceed on a long downhill stretch where you will eventually have to stop your vehicle yourself -run out of road. This roll uphill to a downhill thing really trashes my current ranking system, but that's how 'scientific research' goes, I suppose. The uphill to a downhill section also provides the highest speed of any hill tested to date, 33.1 mph, and the longest roll, .28 mile. Worth the trip if you are in the area. [Greg Brown, 05/25/2001]
