I love sitting outside in a hot tub and watching the snow fall from the sky. I thought nothing could top that. But then I heard about the sauna boat on Lake Zurich and ever since then I can't stop thinking about chugging across the lake with my best friend, inside and enjoying the sauna at the same time. And if you dare, you might even jump into the fresh lake water. Best of all, you don't even need a boat licence. And, with a little luck, you can win a voucher for a trip on the sauna boat worth CHF 450 today. Hit the buttons to win.
