While we were out to dinner, a waiter who sensed that Spanish was not our first language* and sucessfully guessed that we were tourists. He kindly offered his services as during peak season, he works as a guide. His English was impeccable and he was very knowledgeable so was able to tell us a lot about Punta Arenas and surrounds.
He suggested going to Fuerte Bulnes as it was an interesting historical site, so we did. Once we got to the entrance, the man suggested that we should leave our car behind as it was very snowy. It was only two kilometres to the fort, so we decided to continue on foot.
Four kilometres later, we reached the fort. It was very cold but beautiful and it would be the furthest south we would venture on the South American mainland as it ran out of land just around the corner.
Luckily some lovely ladies gave us a lift back to our car on the way back.
If you want to know more about Patagonia or Punta Arenas, I would highly recommend Claudio Silva, the guide at the restaurant. He can be contacted at firstname.lastname@example.org.
*I suspect our atrocious butchery of his mother tongue may have been a giveaway.
