Templo Baha'i Santiago

This striking shell-shaped temple in the Andean foothills is a tranquil spot to relax – even for those who don't ascribe to the Baha'í faith – with an extensive area of native gardens and picnic tables overlooking the city (that is, on smog-free days!). To get here, take metro Línea 4 to the Grecia station, catch bus 506 to Diagonal Las Torres and then walk north along Alvaro Casanova to the temple access road. It's a tough uphill walk, so you may prefer a taxi.
