Millbrook Reservoir

If you’re looking for a solid summer day trip out of New Berlin, this is the spot locals keep coming back to. The small beach is perfect for a swim, and the trail looping around the reservoir gives you just enough of a walk to feel like you actually did something. Bring your kayak or fishing gear — there’s room for both without the crowds you’d get at a bigger destination. The BBQ area makes it easy to turn the whole thing into a cookout, and restrooms mean you’re not cutting the day short. It’s a well-kept town park that punches above its weight.
