Calle Monroy is one of the steepest streets in the world

Calle Monroy is one of the steepest streets in the world. The average gradient over the entire street is 28.1%.

The street is located in Santa Úrsula, a town and a municipality on the north coast of Tenerife, in Spain. It descends from 638 to 430 metres and has a length of only 740 metres. The average gradient over the entire street is of 28.1% , with a slope of 1 in 3.56.
This asphalted street is probably the steepest continuous grade sealed street with public access, with a maximum gradient of 40%. The top portion of the street is so steep that concrete is used to seal this road instead of bitumen or tarmac. There are also grooves casted into the concrete in a chevron pattern to aid in the traction of vehicles that are going up or down this incredible slope.

The road still remains an adrenaline-pumping journey and is definitely not for the faint of lungs, heart, or legs. The last part of the street is very narrow, impassable for 2 vehicles at the same time. Many people are sometimes not even attempted to climb the fantastic street, because this is beyond their capability. This is not the only reason, but it can be dangerous, especialy in case you fail an attempt, you will definitely fall of and slide backwards down the surprising steep slope. It is quite hard to stop with good brakes as it is. On the opposite side of the road, a small shrine stands and reminds of someone who died here. That is why many tourists decide to approach it from the top and descend the whole length of Monroy Street instead.
