You can't beat the Porcupine Mountains if you're looking for wilderness experiences in Michigan. Union Bay is a nice campground to use as a base camp for lots of day hikes in the area.

It can be busy and weekends are louder with kids, dogs, loud neighbors, etc , just like most state parks. Weekdays tend to be quieter even when busy.

Many sites are quite close together and there isn't much privacy in those. Some sites have odd sizes and shapes so be prepared to adjust your rig on the site to get best placement and be level (back in vs. sideways, etc ). Also consider having leveling blocks with you.

Sites in bottom loop offer great views and access to Lake Superior. But even the upper loops are a short walk to awesome shoreline and amazing sunrises.

Bathrooms are clean and showers have good design, although shower heads could use some maintenance.

Staff working the office seem to really know their stuff about hiking the area, so check with them for ideas in addition to the Visitors Center.

If you want the wilderness feel of the Porkies but modern amenities at the end of the day, this is the place.

Note that cellular service can be extremely weak if you don't have a booster.
