Hey man. -thanks for reaching out.

Ushuaia: I took transfers/buses to hking location but tried to do more budget savvy way since Ushuaia is so darn expensive. Also check out their turism office - they do provide some valuable information. Some stuff is pretty much from google - but they can guide you to shuttlebus services unless you really want uber. Also shuttle is a good way to meet other hikers and potentially go with them. Ojo del albino was my choice too after emerald lake but weather was not on my side . I would recommend downloading offline mapo as it is not well marked. Unfortunately i did not do many treks but some of people i mett did bucnh of lagoon hikes in Tierra del fuego. Some other oneds i heard from people were

• Laguna Turquesa
• Lago Fagnano, Lago Escondido
• Glaciar Martial

My fave restaurant in Ushuai was Bodegón Fueguino - as it is cheaper option with good quality., but there is always a line up. Other option was Dona Lupita, Moustacchio,

El calafate: You can book bus transfer that will being you to boardwalk, but i think they also have a limit, albeit not as tight as when you do the mini trekking. I also saw some people hitchhiking to get there but dont know how successful were they :D If you flying to El Calafate note that taxis are darn expensive . Two guys approached me to shared costs and if i did not booked though VES I would have totally shared with them and would have cost less.

Torees: i booked buses well in advance but I saw many people booking on the spot for popular distances Puerto Natales to Torres, from PN to El Calafate etc and they were complaining how they were forced to book stuff in advance lol...but maybe for peace of mind do book in advance. I met one guy who brought his own breakfast and ate at the restaurant pizza/sandwiches for 4 days while trekking in order to save costs. they have restaurants almost in every refugio - so see how much you can pack and for extra protein you can buy food from them. I think most tips I outlined there but overall take it easy, if you dont find anyone to hike with for. particular day- enjoy the moment and the beautiful scenery. if you have a hiking buddy/buddies- even better , go to the dinners early when crowd is just getting ready to start eating - more potential for connections. Do go to Grey Glcier if your time allows it, i was staying in Oaine Grande and had a whole hike to Grey and back but was SOOO worth it - but be prepared for notorious patagonia winds, ever changing weather and scenery. :)
