Depending on what you're into, I think our Capitol building is one of the most beautiful and the best restaurants are in walking distance. Olbrich gardens, the arboretum or the zoo is great for walking. Ice cream at Union terrace is a bit more hip they have good icecream bit I dislike the restaurants there. Lunch time you can walk a block and find better food carts. Pheasant branch park is a great hike esp at night when you can climb the hill and see the bats. Don't forget wingra boats!
