We did this trip at the end of July. Bugs were not a problem. Weather was nice but cool. I wore jeans all week. We liked Munising Tourist Park. I wish they didn't have so many lights at night. We did the Pictured Rock boat tour. Sit on the right side so you see the rocks going out. The falls tour uses the Catamaran, larger nice boat. We stayed at Indigo Bluffs. The RV park side is really nice but very pricey. The campground is nice but most sites are sandy and four sites share utilty post with 4 water/power. Bring extra hose and power cord for this trip! There are web sites to monitor favorable conditions for northern lights. Have fun planning!
