This is just a side road, so there are no entrance fees or, really, any indication other than a small sign. This was very fascinating for me because you seem to be breaking the law of gravity. The road is fairly well maintained and can pull you pretty quickly up the hill if you're in drive or pull you in reverse up the hill as well. A truly fascinating place and it's worth the drive.
It was so cool, cars do really get pulled uphill by the magnet
Interesting place
Love it
My mind was blown
An believe it
Wtf???
There is nothing there. No sign, no marker on the road, nothing. All I can assume is that this place is more of a myth or an urban legend. Your car nor anything else rolls uphill. If you are drunk, or have a good imagination, you may come to a different conclusion. Its an optical illusion and not a good one at that. However, if you are bored in Barahona and have nothing else to do, spend a few hours of your day and drive up here. Make sure you get some GPS coordinates, otherwise you'll never find it.
