Planning hikes in Torres del Paine

Hi there,

I’m thinking of doing the O Circuit or the full W in Torres del Paine—I already did the W about ten years ago.

I’ve got a few questions:

- Do I really need to book everything well in advance? - What’s the budget for overnight stays if I’ll have a tent and be on my own? - What temperature rating should my sleeping bag have for comfort? - Do I need any special gear for the hike? I’ve got low-cut shoes.

And finally, is there a place where I can leave my bike during the hike?

Thanks in advance!
