To cross to Tierra del Fuego you have to cross the Straight of Magellan or Estrecho de Magallanes at Bahia Azul (blue bay). The ordeal was pretty nifty and cold, we waited for the ferry to arrive while looking into the clear waters seeing straight (heh, heh, heh) down to the bottom, someone said they saw a small whale, but I missed it.
We looked across a couple kilometers to the other side that looked a lot like the side we were on. We took a picture and then crossed. On the ferry I ate a hot dog with mayo, mustard, and ketchup. First hot dog on the trip, because it was the only thing they had to offer.
