We did this cruise from Feb 28 to Mar 13 2016. It took us to Puerto Montt, Puntas Arenas, the Chilean Fjords, Ushuaia (the end of the world port, southern most city in the world), then up to Montevideo and Buenos Aires. About 5,000 miles in total.
Going down in that area you can't be sure of the weather. We started out with very good weather and had cool days and blue skies going down the Chilean coast. Saw volcano Orsono (looks like Mt Fuji). The cruising through the Chilean Fjords was awesome, easily as pretty as Alaska. Saw glaciers and the narrow fjords surrounded by mountains were awesome. Puntas Arenas is a small town we walked on our own - saw a few small museums, had a beer. Ushuaia is at the foot of big mountains. The air is crystal clear. Toured apart of the huge Tierra del Fuego National Park for some gorgeous sights.
We did not get to go to Cape Horn - high winds and high seas, and heavy rain made the captain's decision easy. We also did not get to Puerto Madryn due to high winds. Clear skies, but 60 knot wins on the stern. Ship was remarkably stable. Then we got to the big cities, Montevideo (which was nice and manageable) and Buenos Aries (which was big and pretty in places and poor in places).
Typical room. Very clean, comfortable, big enough for the two of us. Not a place to hang out all day of course.
Beautiful. Saw volcano that erupted 10 months ago, walked in volcano ash. Mt. Osorno beautiful from a distance. Great place for alpaca scarfs. $5 each.
4 hours, beautiful locations great weather ,guide gave us an interesting history of the area
Nice walkable city. The old market close to port where lots of vendors cook over open fires is cool (I forget the name). Shop prices are reasonable, especially those that have individual artists selling. Easy to walk into several museums. The Naval Museum - a 20 minute taxi drive, is interesting if you want to learn about the Graf Spee. Tiny mueseum but great video.
Colorful - 1 hour max
Pretty - to walk in and around
Saw the highlights
Good for half a day. Wander the town, see a couple of small museums
Just got on board
