Trip to the NZ South Island

Im spending my holiday in New Zealand South. I have no idea how to organize it. What can I see there? I always have a sort of prejudice that the countries of the Third World are vast and lonely and that people there must be terribly bored. Am I wrong? To be honest, I saw some pictures of New Zealand South Island and I must admit that I liked them very much.

New Zealand is a beautiful country. If you like horse-riding, you may choose from a horse with the unknown bred to a Welsh pony and ride it at one of many horse treks. Your ride is guided all the time by an instructor. You may drink wine at one of the cellars because the southern part of New Zealand is famous for wine production. People from New Zealand are especially fond of Pinot Noir. You can visit the Southern Alps; a range of mountain cutting The Island alongside. You can also rent a motorcycle or go fishing or hunting. I practiced none of the mentioned activities. I spent my time walking through wilderness and thinking. It was really a healing experience.
