The bike around Lake Monona is a beautiful, mostly flat, 11 mile ride. There are even a couple ice cream shops along the way if you are so inclined. Rent an e-bike for a power-assisted excursion.
The farmers market is on Saturdays from 6 am - 1 pm, get there by 8:00 am to avoid the crowd. Explore culinary delights ranging from fresh-grown carrots, tomatoes, mushrooms to jams, cheeses, breads, to meats and beverages. A time well spent.
The terrace at the Memorial Union on campus is a beautiful way to spend a morning, afternoon, or evening. Right on the water you can enjoy a variety of beverages and food while you are watching the wildlife (aka: college students) in their natural habitat.
