Avenida Santa María 2201
Parque de las Esculturas makes a perfect end to a long day of being up on Cerro San Cristobal, as it's on the way down Pedro de Valdivia back to the metro. However, it merits a visit of it's own. It's an attractive gated garden with a number of both representational and abstract sculptures varying in size from quite small to a series of metal bars you can walk through. It's along the Mapocho river, and enjoys a cool breeze at most times of day, though there is little shade to protect you from the sun.
There are scuptures made of wood, stone and metal, and it's a popular place with the teenage crowd, most of whom either sit and enjoy the sun, or work on building their own summer (or winter) romance.
In the summer, there is a series of Jazz concerts hosted here, which you may pay for a ticket to enter, or sit outside on a blanket and enjoy the music for free. During the rest of the year, entrance to the sculpture park is free, and it is open during daylight hours.
