This is the only big hill in the city. On the top, you have a great view of the city and if you turn 180° you have a nice view on the Las Americas Bridge.
Reviews on Trip Advisor tell that early in the morning there is a chance to see little monkeys and other small mammals.
How To Get There
You can walk from the parking lot (See my Map) about 20-30min to the top.
Or you can drive to the top if you feel lazy, but the road is so narrow that the security man has to wait for the road to clear before you can go up.
So in our case the security lady just told us that we couldn't drive up :S. So maybe you call a taxi, because security won't just tell a local taxi driver that he can't get up there.
