When you feel like a walk in the middle of Winter, you'd have a hard time going unless you put on a pair of walking skis. There are two ways to enjoy this pastime: one, when you take yourself on the many kilometres of prepared cross-country, or 'langlauf' walkways, kept by the municipality and well signed.
You can buy maps that clearly mark these paths, and as moving on skis is faster than walking on foot, you can cover further distances in the Winter than you would in the Summer, and see much of the countryside, stop off in villages for a mulled wine or beer, go alone or in groups, and take it easy, or exercise your athletic prowess :-)
Two - and this is what I prefer - is to go into uncharted territory and make your own marks. There is nothing like the feel of the snow squashing under the narrow ski. Of course you don't cover as much ground as you would on a made-up langlauf highway, but, especially when going quite alone and being quiet you meet animals: hares, rabbits, deer.... I even saw a fox as I was coming back the other afternoon close to dusk.
I love this country with all it has to offer. And being here in Krumlov means you needn't go far to get these pleasures: five minutes outside the town, and you are in a forest. So you have the best of both worlds.
