El Plomo is the biggest mountain you can see from Santiago, 5,400m tall. I set out to climb it with Neil, who'd tried once before and not made it due to bad weather.
We drove to Valle Nevado and across the back country to Tres Puntas. We'd set off quite late from Santiago but our first day was very short - an easy two hour walk to Piedra Numerada, a broad green plain 3,400m above sea level in the valley of the Río Cepo. It was 8pm when we arrived.
