Actually, I take a little meths stove even on a day walk. Even if I have cold food, making and drinking a hot brew when I stop is a real pleasure, and the whole outfit only adds a few hundred grams to my pack. Yes, I could go without the stove, but that moment when the stove's lit, the water's warming and you're forced to sit for a few minutes enjoying the view and anticipating a hot drink is definitely part of the enjoyment for me.
