On my last day in Patagonia (4th February), as my flight was re-scheduled, I had time to do one more hike. I went to Estancia Tunel, it's a private property but you can hike to it and the trail was really nice. It's also possible to see Ushuaia and the famous lighthouse (which is quite small: 11-meter tall brick tower, with the light itself located at 22.5 meters). 

On the way back I took the local bus A, it was possible to use the same SUBE pass that is used in Buenos Aires. Then I walked to Ushuaia airport, it took me about 50 minutes. I arrived in Marcela's apartment in Buenos Aires at 3 am, because the plane was one hour delayed and I had problems with transport from EZEIZA airport. I took the local bus 8 and then a taxi from Plaza de Mayo ($13).
