About Union Bay - Porcupine Mountains State Park

Union Bay-Porcupine Mountains State Park is home to a seasonal campground that is available to visit from mid May to mid October. With a limited window of time, it’s well worth planning your trip in advance, as peak season can bring a gaggle of campers and tourists, making priority campsites difficult to find. The initial weeks of August are almost always packed, thanks to kids and college-students trying to camp before school starts again.

Subsequently, if you want smaller crowds but still want to enjoy the sun, try to reserve a spot during the latter end of August. This is also when the Porcupine Mountains Music Festival happens, giving you a great event to check out. Regardless of your needs, during camping season you can call the campground where staff will provide details on sites that you might not see at the Reservations Center or online. If you can’t find what you’re looking for online, give them a call!

If you happen to forget a thing or two, there’s the Porcupine Mountain Outpost store right outside the entrance to the campground. It's open from May through mid October. There you can find souvenirs, camping supplies, and even clothing. You might find the occasional pre-made sandwich, but besides soft drinks and milk, there are no real groceries here. You’ll have to travel all the way out to Ontonagon (25 miles away) for groceries. That said, you can make the trip worth if you if you grab a bite to eat at Syl’s, a legendary diner famous for its repertoire of comfort food classics.

The campground itself is moderately sized, with 99 sites available for RVs and tents. One of the draws to the campground is that all sites have at least 30 amp electric hookups available. One of the most common complaints here is due to the limited amount of pull-through sites, with many options too small to accommodate larger vehicles.

Porcupine Mountains State Park is uniquely known for its hybrid existence between contemporary and antiquated beauty. The park is extremely modern, thanks to the updated facilities and well maintained grounds. However, it skirts the line with a true wilderness feel, owing to the rustic touches, and charming yurt cabins, available for overnight accommodations as well. Whatever your intent to visit, there’s no mistaking the quant appeal of this Michigan state park.

Beautiful family campground

Beautiful family campground on the North ashore of Lake Superior. It has RV, tent and back country sites as well as cabins and yurts for rent. Many amazing hiking trails and beautiful waterfalls to explore near by. Campground has large clean bathrooms and showers and a nice camp store. It is also pet friendly and has WiFi,  but no playground.  We stayed at site 82 which had a partial view of the lake and backed the tree line. It was a nice site. I gave this campground 4 out of 5 stars because some of the sites were a little too close together but overall a great campground and we will be back!

Gorgeous sunset and Sunrise in July.

Great park. Explore 100 miles of trails and sleep under the stars. Love the sites on the water. Reserve early as it is booked during July and August.  Firewood available at outpost store just before you enter park. Be sure to stop and pick some up before you check in. It’s kind of a far walk when hauling wood if you are driving a motor home.

Hiker's Dream

The campground itself is clean and has large sites on the back row, smaller sites on lake superior, and average sized sites in the Center. There are many hike in sites available for tenters, and also hike to cabins and yurts. The hiking is in the mountains and mostly point to point. Be prepared to hike some distances with steep climbs and descents, and uneven footing. At the visitors center they have suggested levels of difficulty and numbers of hours for various hikes posted on the wall. I recommend a little research before starting your hike. We loved the lake of the clouds ridge hike and the presque river water falls hikes. Beautiful sites and peaceful hikes. Often there was no one else around. We found we had the sunsets at lake in the clouds all to ourselves.

Beautiful park! Must come back!

This is a very large park! It took me 45 minutes to drive across the whole park. My favorite spot was prequel isle with the water falls! There is also a cliff face to hike along and see Lake Superior. Another noteworthy attraction is mirror lake!

Great Base for a Weekend of Exploring the Porkies

The big thing about this campground is the size of it.  Positioned on a hill like feature, It has an hill-top section and a bottom of the hill section.  Some of the sites at the bottom are a little rocky, so not great for tent camping, but for campers this would be an ideal location for it overlooks Lake Superior.  The top section is great for tent camping for it had an abundance of grassy sites.  This is a very picturesque campground and one that is a great place to call home for a multiple day adventure to the Porcupine Mountains and has amenities such as showers and restrooms.  It really takes you away into nature and provides a unique view of Lake Superior from a beach of stone.

Crowded, but for great reason

We absolutely loved camping at Union Bay! There were a lot of people, but they aren’t so close that it’s annoying. There’s electric at all the modern campsites, as well as the typical picnic table, fire pit combo. While the site itself was sort of small (ours was not suitable for anything other than tents) I actually enjoyed having all our stuff close by. When you stay here, don’t forget to put your trash in your car! We didn’t and we’re visited by a pretty sassy raccoon 😂 The sunsets on Lake Superior were amazing, and we even saw an awesome storm coming in that ended up just being a lot of wind. Short drive to tons of hiking trails, including the Escarpment trail which is one of the most amazing hikes in Michigan. If you’re hungry, there’s a great diner in Ontonagon that has amazing pizza and breakfast! Totally recommend and will definitely be back! (ps prepare for black flies, deet doesn’t even scare the little vampires and they are literally everywhere. I recommend bringing a good anti itch stick/spray)

Campsite #30

Pet-friendly. Site was able to be reserved online for overnight tent camping - however, it was labeled a "day-use" or "group" area - not sure if this was a fluke or what. Beautiful site right on the shores of Lake Superior with amazing views. The campsite was really busy, the sites looked packed together offering little privacy. This site is tucked away in a corner so you only have one neighboring site. Flooding would be a concern if expecting rain.

So much to do/see

Our first night here there was a tornado watch so we decided to move our gear around and sleep in the car as not to risk any damage to our tent etc. One thing to also keep in mind is that if it is raining almost every site we saw at this campground was extremely muddy! Ours was awful. The next morning when we woke up we hiked the escarpment and summit peak. Due to weather conditions that’s all we were able to hike but the views were incredible and the hikes were fun!

Clean, modern- not a lot of privacy- except the yurts - they are phenomena!

Right on Lake Superior, best sites are often booked early- but the yurts are considered “back country “ even tho East yurt is next to a private parking spot and West is 70 yards away both with direct private access to Lake Superior

Beautiful location, Very Muddy!

We were there over Labor day weekend. Campground was full. We had rain so everything was really muddy. Site are all just in the grass or dirt. I wouldn't recommend camping there with a tent if rain is in the forecast. Sites are close to another but it's nice to have electricity. Setting is beautiful.
