Best Time to Camp at Porcupine Mountains-Union Bay Campground

Lake Superior's moods shape the camping experience here—pack layers even in July, as cool winds sweep off the water and can make evenings brisk and invigorating. Spring rains may leave some areas of the campground temporarily muddy, and mid-season visitors should come prepared with insect repellent, as black flies and mosquitoes can be intense during certain weeks. These minor challenges are simply part of the authentic wilderness experience that makes the Upper Peninsula so memorable.

Spring (Mar-May)

Wildflowers bloom, mild temperatures, fewer crowds. Great for hiking and photography.

Best

Summer (Jun-Aug)

Peak season with warm weather, perfect for water activities. Book early.

Fall (Sep-Nov)

Beautiful fall colors, cooler temps, quieter campgrounds. Ideal for peaceful trips.

Winter (Dec-Feb)

Off-season, limited services. Check for closures before visiting.
