Continuing my cautious recovery from back surgery, I went for a walk up Cerro Calán with Amy. The top is 867m above sea level but only about 50m above street level. We thought we'd walk up to the buildings of the Universidad de Chile who have their observatory there, but it was a weekend and the gate was locked. So we wandered around the hill looking for another way up to the top, and eventually found a fence we could duck under to take a path to the back of the university buildings. And from there we saw the sun setting behind the city.
