It's true: winters can get a little rough in Wisconsin. That's why places like Olbrich Botanical Gardens are heaven-sent. Filled with heat and humidity, the gardens are a little retreat in the frozen tundra. If you can pair up the timing with the Gardens' Butterfly Exhibit--even better. Nothing like a wonderland of warmth sprinkled with the color of butterflies flying overhead.
In any season, this place is a must see!
