for those who live up there, you have a WOW factor in your area for sure. Only thing I wish I had done even though a tad pricey (what is not) is take the 2 1/2 hour 38 dollar boat tour of the cliff sides and waterfalls from Lake Superior out of Munising MI We thought we could walk most of it, which we did, but each walk to see something WOW factor was between 2 and 8 miles IN then same OUT with on average 4-6 mile walks thru woods, over trees, up/down steps so not as easy as just 'walking'.
I think the whole shoreline is near 40 miles long but to get to most WOW spots to see waterfalls /cliff sides was a few miles inward, and then some, which basically took 1/2 your day (4-5 hours or so total walking) and did not have 6-7 days to see it all, but 3-4. I even ran out of SD card storage on my cell phone taking so many videos and pics in the week up in northern WI and into Michigan.
I did find out from several places that the snowmobilers up there in winter do NOT like ATVer's going on 'their' trails in the winter even though is legal to do. They said the snowmobilers up there will slash your ATV tires or wreck your ATV for just showing up doing nothing wrong. Nice folks up there aye??

Regardless of what they say, if in low 30's for temps and plenty of snow as there usually is way up north, if driving sensible/normal, NO ATV tires will ruin the snowmobile trails, is a myth. They just do not like sharing the snowmobile trails in winters with ATV's since it probably slows them down only able to do 30-40 mph vs. snowmobiles going 100 mph.
I heard this from several up there even one trail groomer for snowmobiles who worked for an ATV/snowmobile dealership up there since even he got ripped on after grooming the snowmobile trails for hopping on his UTV to ride home after smoothing out their trails. He sees it every winter snowmobilers puncturing ATV tires or otherwise harassing ATV users in general in the winter up in northern MI.
Even did 177 miles in Hurley WI ATVing and seeing great waterfalls (about 9) in the WI area as well as the black river waterfalls in Michigan another 30 miles north of Hurley which IMO was the BEST of all for waterfalls that is a series of 5 larger waterfalls all on same road, same river, about 1/2 mile apart from one another and easy 1/2 mile walk in to see each one with each one having their own smaller separate parking lot taking only 3 hours total.
Porcupine forest in MI was o.k. but could have skipped it was not too impressed with their 3 waterfalls but still worth seeing.
ATVing in Hurley WI was very good as well but they could do some trail grooming especially first 5-6 miles and more OUT of town for there are rocks and potholes (filled with water) a foot deep EVERY 10 feet to either go thru slowly or go around slowly since top speed 15 mph for miles and miles takes forever. They probably do that on purpose to keep safety having to go under 15 mph for dozens of miles. We went out on a Sunday on the ATV trails (routes) did most all trails and a few high speed gravel road routes (smooth as butter can go easily 50 mph) and was well worth it since only saw 3 other ATV/UTV''s out there from 8 a.m. to 6 p.m. all day. I guess they had an ATV benefit run on Saturday was very busy so glad we did it on a Sunday no one around was sort of shocked so not busy but was thankful for that as well as NOT blowing an ATV tire on all the rocks/boulders having to go on, very rocky all over the trails and thankful for NO rain since can see those ATV trails up there when wet and muddy being very slippery and dangerous going up/down steep rocks/mud mix.
