The Kettle Moraine State Forest consists of northern and southern units that frame Milwaukee. The Northern Unit is less than an hour's drive away from the city and features several biking and hiking trails (including part of the famous Ice Age Trail), campgrounds and fishing and hunting sites.
A not-for-profit organization, the Pettit National Ice Center offers public skating as well as lessons in figure skating, hockey and speed skating, as well as the only indoor run/walk track with a Zamboni Crossing sign. This center is an official US Olympic Training Site, and the only indoor sea-level oval in the US available to our country's athletes.
