U/P Michigan or Minnesota?

A lot of Minnesota can be just as hot as Missouri in August, plus you have to put up with the mosquitoes too, and the humidity can be equally fearsome. We spent several summers there when I was a child. Lots of lakes though if you like to fish, boat, or canoe.

I was in the UP in August after leaving the Oshkosh fly-in and the weather was pretty pleasant. However you'll have to get more information from someone who had been there more than the one time I passed through.

My choice would be the UP.

Both places are great to visit.We like the upper U.P. the best. When it gets hot we go over and camp by lake Michigan to beat the summer heat. Have a great vacation.

Both northern Mn and the UP can be hot, humid, cold, dry, wet, rainy, or sunny. The bugs can be bad in both places. Not much of a difference. If the wind is from the north, drier and cooler. Wind from the south means warmer and more humid.

Both places are beautiful and peaceful, if you find the right campground.

In MN, the state parks fill up fast for August. All state parks with camping have some non-reservable sites. Get there on a Monday morning or Tuesday morning and you can nab one of these and stay up to 2 weeks... There are a few electric and non-electric sites in this category.

There are plenty of city, county, and private parks in the upper half of MN. Finding a place to camp shouldn't be a problem...

Good luck

Having summered in the U.P. several times, and visited lakeshore Minnesota, I would say your chances of cool weather are about the same both places if you are on the Lake Superior shore, but most of the rest of Minnesota might as well be in the Dakotas or Iowa, hot continental summer climate.

That being said, one late June day when I was in Marquette it set a record as the hottest place in the U.S. that day, and the next day it was the coldest. The storm in between was really interesting and I was happy not to be camping that night.

No guarantees.

Despite being Northerly, Michigan's UP is anything but cool in the summer time, and the mosquito's love it up there, hot, humid and lots of ground weather.

Its cold and humid right now in Northwest Lower Michigan, been that way for more than a week. Forest Festival will start in a few days, HUGE draw for tourists.

The state parks in the U.P. are very nice and you haven't mentioned what hookups are a must or what you will be camping in. For a CG, I have to assume that electric is a must and a min of clean bathouses and showers plus a dump station and having fresh good tasting water to refill your tank.

For a week stay with camping in one or any Michigan State Park, it's cheaper to buy the annual pass which is good for any of the over 100 state parks. Most state park CG's are about $22 a night for the site in the U.P. So much to do and see all over the U.P. and it will be much cooler than in MO. Bring a light jacket or a sweatshirt for at night as it can be in the upper 50's overnight and usually the mid to upper 70's and sunny during the daytime.

Tahquamenon Falls state park has 3 CG's and it's a gorgeous area. North of Tahquamenon Falls on Lake Superior is Muskallonge State park CG. Porcupine Mtns State Park is about 60,000 acres with the CG on Lake Superior. Indian Lake State Park at Manistique is real nice and there's the huge Palms Books springs a few miles away. Straits State Park at St. Ignace is great with 2 CG's and Mackinac Island and the huge bridge to the Lower Peninsula. Just a small spattering of the many state parks in the U.P. Gobs of nice CG's in the Lower Peninsula too just by crossing the 5 mile long very high bridge.

Some really like Aune Osborn CG in Sault Ste Marie, MI as it's right on the wide river next to the SOO Locks (the world's busiest locks) that has huge freighters passing close by every day.

If you want cooler weather and a laid back atmosphere, head up the the Keweenaw Peninsula in the UP. The entire peninsula is surrounded by Lake Superior so if you are near the water it is very comfortable in the hot part of summer. Plus the lake temp is usually in the 50s so a quick dip will cool you off ;).

Check out Ontanagon, Hougton, Hancock, Calumet and Copper Harbor. All are great little towns.

I would recommend the Porcupine Mountains State Park (right on the lake), McClain State Park (also on the water) and Fort Wilkins State Park.

If you have never been I would highly suggest seeing Lake Superior either from MI or MN or heck, head up into Ontario. There is nothing else like it in the world.

There is also some beautiful places in Northern MN. The area around Voyagers National Park is very nice too.

We've been RVing in the UP well over a hundred times during the last 51 years of our RVing and seldom found mosquitos to be that big of a problem in August, September, and October. May and June is early hatching on the wet areas and the worst mosquito time. July is the buffer month between.

Need a passport to go into Canada now with your vehicle and if you have a pet with you, all papers for proof of required vaccinations must be with you.

If on a US based cruise, you will need a birth certificate and a government issued photo ID.

The OP lives in Missouri and it's not a state that issues an EDL (Enhanced Driver's Licence) like Michigan, New York , and Washington does for using to go into Canada.

In MN I'd go to a park on the North Shore along US61. In MI I'd go to the Porcupine Mountains State Park and Ft. Wilkins State Park in Copper Harbor. Probably need reservations at most parks up north before Labor Day.
