Port Stanley. Took the NCL tour of Port Stanley and environs. It was nicely done in a 40+ passenger city type bus. Spent the rest of time in port exploring Port Stanley on foot. The Victory bar had good fish and chips and an interesting cast of characters. Some sort of tour is worth taking. Port Stanley is small and very walkable but you don't get the history without a guide.
Took a non-NCL tour by van with about 7 people through the National Park outside Ushuaia. It had beautiful Alaska like scenery and we had a good guide. Then spent time walking around Ushuaia. The town is interesting and fun to walk around. Just knowing you are in the southernmost city in the world is a kick.
Took a non-NCL tour with 3 people in a van and an excellent guide. Went out to Ft Bulnes and our guide and us were the only people there. It's an interesting old log Fort with several nicely restored buildings. Then we got a tour of the Punta Arenas Museum, a tour of the cometary which is a smaller version of the famous Ricoletta Cemetary in Buenos Aires then and a driving tour of the town. Then we walked around town.
NCL tour with 40+ people on a bus. Drove through spectacular scenery, took a 1 hour trip on a beautiful lake in a 300 passenger cameraman.
We were supposed to see Puerto Montt on the return but there was big event io town that had several streets blocked so our tour guide gave us extra time in Puerto Vars where the was pleasant to see and a nice public square with a beer festival going on. We ended up with a very good lunch in a restaurant overlooking a beautiful lake.
