Kettle moraine trail access here
Mauthe lake is in the Kettle Moraine Northern Unit. It feels remote but we drove through a bunch of rural houses on the way in. The rustic roads made for good cycling. We passed quite a few pedaling up and down the hills.
The campground itself sprawls along one side of the lake. With the loops for each group peeling off, it is easy to lose your way. The signs mark the direction well so go slow. It helps to know your site number.
There was nobody at the entrance office. I’m not sure if it’s just today but make online reservations. It seems to be the 2022 way.
There is a shower house but we made use of the more convenient vault toilets. Water is available in different ways - even a drinking fountain. There seems to be only one garbage collection site on the way out. This was less convenient since we have dog droppings to deal with.
There is a nature trail that goes around the lake. By the beach and picnic area it’s paved. The rest is gravel or dirt. With recent rains we found a few puddles to walk through and mud to avoid. Our dog loved having the trail so close. Most of the trail is in the sun so bring water on hot days.
Swimming isn’t allowed due to a blue algae bloom. This left plenty of empty space for us to sit with our dog under the trees. Folks did make good use of the fishing pier and playground. We also saw kayaks and stand up paddle boards on the lake.
