It´s the most well know spot for going to chill put with your friends. Locals love to go there to drink mate (a whole thing on its own) while watching each other. From the top of the hill you can see an amazing sunrise and sunset.
You will see the best view of the coast of Montevideo. Also, it is over the seashore, so you can walk there, have a rest watching the sunset and keep walking. There is a very good restaurant on the hill to have a beer or a coffee.
Don´t forget the monument at the top.
