We have backpacked the circuit two different years. The W route is a subset of the circuit. I did do an extensive blog entry when researching the trips, and updated it afterwards: My Blog entry on Torres del Paine preparation - I've incorporated some of the post's more useful information here.
Since that time Susan has incorporated all that information plus her journal experiences and more into a book: Patagonia Chronicle: On Foot in Torres del Paine. That book is described more fully on its own web page Patagonia_Chronicle.
At the moment our most recent information is in the book, but as we get updated information I will add it here.
One question that has come up from a reader is "Where can we charge our devices while on the circuit?". The short answer is don't depend on it. Take enough spare batteries to last you for eight days. We took two camera batteries apiece. In the outlying refugios (Dickson, Chileno, Grey) they have generator power, and if you are staying in the refugio or can convince someone on the staff, you might be able to get a couple of hours of charging. I think that in the Torres Central Refugio there was an outlet in the dorm room. We got the bartender there to charge our batteries while we were at the bar.
One important link has changed since we put the book out. CONAF is redoing their web site, so the official map is no longer at parquetorresdelpaine.cl/maps.html. There is a copy of it at www.torresdelpaine.com/img/portada/mapaPAINE.jpg
When we did this trip there were only two guides available that were at all useful, The Lonely Planet guidebook for the area and the Moon Guide for the area. Since then Cicerone has put out a guide for Torres del Paine, and Susan's book is available.
Torres del Paine: Trekking in Chile's Premier National Park (A Cicerone Guide), Rudolf Abraham. This wasn't available when we hiked, but it is the usual excellent very detailed Cicerone guide on hiking the trails of Torres del Paine.
Patagonia Chronicle: On Foot in Torres del Paine, Susan Alcorn. This provides a hiking guide that falls somewhere between the Lonely Planet guide and the Cicerone guide. Her journal narrative provides a sense of what is actually like to hike the Circuit. The planning section provides an excellent guide to making the trek, and the human history and Patagonia Today chapters complete the picture.
Moon Patagonia Including the Falkland Islands, Wayne Bernhardson. We relied on this for information on the Lake District and broad Patagonia information.
My blog post was mainly about useful links. Maps were a major concern. A useful map link:
One of the best trail maps: http://www.interhabit.com/torres_del_paine/map_615.htm click on the Torres del Paine map at the bottom of the page.
Cariedaway has one of the best blog posts I have seen on the nitty gritty of hiking Torres del Paine, including a hand marked up trail map that I particularly like: cariedaway.blogspot.com/2013/12/planning-your-trip-to-torres-del-paine.html
Besthike.com has a good writeup on tdp, including some maps that highlight the W and Circuit: www.besthike.com/southamerica/chile/paine.html
I found some sites with gps maps, and others with gps tracks, but didn't find them accurate during our trip - offset about a mile, so I must have had wrong base. Gps was unneeded anyway, as the routes were fairly obvious, even when trail markers were confusing.
The hardware stores in Puerto Natales sell white gas - it's called bensina blanco.
You can buy isobutane canisters in town the brand is Doite - from Korea. We got canister in Punta Arenas, numerous stores sell in Puerto Natales. Also, Torres alburge Central - the big refugio that you first get to if entering from Laguna Armarga, had canisters but I would try to get it earlier, eliminating worry about shortages.
Transportation is a little tricky. Argentina and Chile don't get along all that well. There are three towns you need to remember. Punta Arenas on the Strait of Magellan, the largest city in the area and a transportation hub for Chile, is where you would fly into from Santiago, then bus north to Puerto Natales, the gateway town to Torres del Paine. North of Torres del Paine and Puerto Natales is El Calafate - the Argentina transportation hub. From Argentina you can also fly in and out of Ushuaia or Rio Gallegos and fly from there to Punta Arenas. There are daily buses from Puerto Natales to El Calafate. Currently buses leave Puerto Natales for Laguna Amarga, Pudeto and Administration at 7am and 14:30.
According to the fslodges.com , there are buses leaving Punta Arenas every one to two hours for Puerto Natales, starting around 7 am. Catch Buses Fernández at Armando Sanhueza 745, or Bus Pacheco at Avenida Colón 900 or Bus Sur at José Menéndez 565.
From Puerto Natales, buses leave for the park at 7:00 am and 2:30 pm - Buses Gomez at Arturo Prat 234, Buses JB at Arturo Prat 244 or Buses Turismo Maria Jose at Bulnes 386.
Buses Gomez site is: http://www.busesgomez.com/ When I last checked, they left Laguna Armarga for Puerto Natales at 15:00 and 19:45. You would catch a shuttle at Las Torres Refugio to connect at Laguna Armarga.
You can bus from Puerto Natales to El Calafate, and from there get a flight to Buenos Aires for about $290. It can vary by day of week. Our plane was full leaving, so book in advance. You can get a ticket from Punta Arenas to Buenos Aires, but it routes you thru Santiago and costs more. For Brazil flights: http://plane.lan.com/index-en-us.html
There is also a little Argentine town south of Punta Arenas - Ushuaia and people can fly in and out of there, to Buenos Aires, but costs more than El Calafate.
Our 2010 route was to fly from Santiago into Puerto Montt, stay at Puerto Salas a couple of days and then take the Navimag ferry to Puerto Natales. After that, same as last year. Note that there is only one ferry a week from Puerto Montt to Puerto Natales.
For 1 person economy - for a 12/15/13 depart, 1/6/14 return, sfo to Santiago, Buenos Aires to sfo = about $1600. Double that for immediate departure so book flight well in advance. We booked the flights from Santiago south and return to Buenos Aires separately thru LAN.
For Santiago to Punta Arenas $514
For El Calafate to Buenos Aires $284
For Santiago to Puerto Montt $214
Navimag ferry, bunk in dorm $420.
In Torres del Paine, we always camped, but bought breakfast and dinner when available. On a per person basis, breakfast and dinner was about $42 US dollars, and campsite $16, so about $120 per day at the fee sites for the two of us for 7 or 8 days (two days were at free camping sites). As we were camping, we had to pay in Chilean pesos, which include a 20% tax not in the published dollar rates, so the $120 above is adjusted for that 20%. i.e. we paid in pesos and I'm giving you the dollar equivalent. We brought about $800 Chilean pesos from home, and also used ATMs in Santiago and Punta Arenas. For Argentina we just used ATMs and credit cards.
We had a 10 day plan for the Circuit.. We planned on eating breakfast and supper in refugios and carrying 3 days of food for the cases where there was no refugio with food. We carried lunches for every hiking day. Los Perros is staffed, but doesn't prepare any meals, so we needed dinner and breakfast for there. From Los Perros is is 22km over Garner Pass to Grey Refugio, the next one with food. We stopped instead at unstaffed (and free) Campamento Paso, only 12km from Los Perros. Our next unstaffed stop was at Campamento Italiano. The remote refugios only have radio communications so don't take credit cards. Las Torres refugio does take credit cards.
240 volts. You need the round 2 prong adaptor for Chile (3 if ground required), Argentina 2 round or two diagonal. Remember that you need a voltage converter, not just a plug adaptor if your appliance requires 110 volts. My camera battery charger will convert 240, but my cell phone charger will not.
The refugios all had water from a faucet, and we drank it unfiltered with no problems. One day a storm knocked out the water at Seron, so I filtered muddy water from a stream using our ULA gravity filter. At Italiano and Camp. Paso got stream water. Carry water purification tablets for backup.
We both had Packas - rain parkas with sleeves, zippers, and a big hump for the backpack. Worked fine, but only protects to about the crotch. We also had rainpants. Also, I carried Seal Skinz waterproof socks.
We used essentially the same gear list as our state of Washington Pacific Crest Trail list included below. Any changes for Torres del Paine are noted:

John Garner Pass. This was answered by John Garner himself in an interview with Anne Crawford of the Sydney Morning Herald, Travel, November 13, 2008. Ms. Crawford encountered Mr. Garner at Refugio Grey, along with his two ranger friends, Pepe Alarcon and Oscar Guineo, They had pioneered the Circuit trail in 1976, and were having a reunion. See her full story for more details. www.smh.com.au/travel/ice-bold-20081113-645i.html
