Lake Silvaplana has breathtaking views year-round, but in the winter there's another delightful experience to be had: walking on transparent ice that allows visitors to see all the way to the lakebed.
Kevin Walker (talk about nominative determinism) takes us out for a walk, and he gets some really nice drone footage while he's at it.
Bonus video: will this person drop through this way-too-thin ice?
