Penguin highways are an important part of penguin transportation. When they first get ashore, they seek out rocky spots but snow can sometimes get in the way. Snow can be a couple feet high if not more in certain areas. The penguins will march across certain areas until they compress down, creating distinct penguin highways, areas that are carved out by the weight and movement over the area. These allow easy access between their nesting places and the water.
Penguins will also toboggan across the snow because, as I mentioned in another penguin post, they don’t do so well on land… They do have claws to provide extra traction over the snow and rocks though.
As a visitor, it is important to not step in these as the penguins have worked hard to create these highways.
