You get electric, period. Dump station available, potable water available there, as well as various spigots within the park. Beach ok but narrow. Firewood available, with free loaner wagons to get it to your site. I found the west side of the park a lot noisier than the east. The separate south campground was closed for repair, so I can't speak to that. Be aware that in summer, thousands of tentworms will be on virtually every tree, often falling on you when you're sitting around. They get on your awning, so be careful before rolling it up.
East Tawas is a place I've visited most of my adult life. There's some walking trails here, the lighthouse is a close walk/bike from anywhere in the park. Getting to town is a few minute drive, or a very long bike ride on the road.
Like most Michigan State Parks, your site has electric (30/50) only. Water spigots are located in various spots throughout the park. I advise you fill your freshwater tank at home, or when you arrive, at the dump station.
There's a few ADA sites with concrete pads, all others are grass. Comfort stations are in good shape.
Beaches are, like most in Michigan, eroded due to high water levels, but still useable.
You can watch sunrise on the Lake Huron side, sunsets over Tawas Bay.
I've never really interacted with staff here, but never needed to. Park is clean. There can be lineups at the dump station.
A few sites are pull thru. Most back-in.
If you have a vehicle, there's many places to see in the area, like Lumberman's Monument. Tawas has a nice farmers market, worth a visit for fresh veg and other items.
Like most Michigan State Parks, you get electric (50/30) at your site, period. There's public water available at various spots, but not at your site. Rangers are a good bunch here, friendly, helpful and work to keep things in line.
Most sites are very sandy (the whole place is ancient dunes), but dries pretty fast after rain. Dunno what one review is talking about, this place has tons of trees & shade in probably 90% of the park.
Beach is across the highway with a pedestrian bridge. Water levels have eroded most MSP beaches, but this one is still usable.
There's a couple concrete ADA sites, often occupied by non-ADA campers. ADA sites are pull thru.
Bathhouses are ok. Nothing fancy, but have been clean in my experiences.
Can get a little loud on weekends and holidays, but during the week it's mostly peaceful.
We stayed 3 times last year, and have already booked again this year.
Nothing really bad. Lots for kids to do, sites not completely level. Pizza was good. Propane fairly priced.
Good cable, easy hookups. Most sites have dual sewer connects, makes it easier.
One drawback.. I assume owner was riding two different motorcycles, and a gator, so a little noise then, but mostly quiet and nice at night. I would stay again.
Road leading in is VERY narrow, don't know how two rigs could pass each other.
Get a patio site if you can, they're very nice.
Grass sites, fairly level. LOTS of red ants on my site, got bit pretty good. Rained overnight, and my site was fairly swampy when I was packing up. Was quiet, could hear some road noise, not bad though. Some permanent sites. I'd recommend this only for a night. Was cheap.
No picnic table or fire pit. Basically parking site. Cable TV ok, water power and sewer ok.
My site was covered in dried mud, cigarette butts all over. They don't seem to clean the sites much. Showers/restrooms need better cleaning. They allow local traffic to cut thru park, I can't imagine why, and it's fairly non-stop all day. Never seen a park do that. Speed limits (5MPH) rarely followed. Fire pits and picnic tables oddly located about 25' from the back of your pad. Sewer/water can be a reach. (I needed 20' of sewer hose, 25' of water.) Electric is right on rear corner of pad, driver side.
The good: Sites are concrete pads, level. Staff friendly. Saw rangers often, but they never warn people to slow down. Nice lake. Multiple playgrounds for kids. Paved walking trails. Paddle boat rental. ($10/hr). Plenty of room between sites, easy back in. Firewood avail.
