Hidden treasure
First off, do NOT try to get map directions to Huber Campground. That might be the actual name of the campsite, but if you want to find the place, what you're looking for is the "Menno Lake Recreation Area."
Once you do, however, you'll be blown away by the beautiful lake that stretches, well, not to the horizon, but well past your field of view. There's drive-in camping for cars and RVs, electric hook-ups, tables and fire pits, along with a pavilion for a picnic meal, and a small playground for the kids.
Potable water is available near what I assume is a maintenance shed, not far from the fishing docks and public boat ramp.
One of the two toilets (both pits) is ADA accessible. The other one features side-by-side toilets for those who are very comfortable with others.
Located a fair piece from the nearest grocery, I recommend you stock up before heading out there.
