Union River Outpost offers three rustic tent sites tucked into the Porcupine Mountains backcountry at 784 feet elevation. The small loop sits in a hardwood and hemlock forest along the Union River, with vault toilets and no potable water. Sites cost $17 per night and book quickly due to limited capacity.
Rustic three‑site outpost campground (vault toilet, no running water on site); described as ideal for tent, van or compact campers and offering a secluded, backcountry‑style experience.
Weather and SeasonsFall brings the best conditions. Daytime highs sit in the mid-40s to mid-50s°F from late September through October, with nights dipping near freezing. Peak foliage runs late September to mid-October, lighting up the hardwood and hemlock canopy. Crowds thin after Labor Day, leaving trails and riverside spots nearly empty on weekdays. Late spring and early summer mean heavy mosquitoes and black flies. Bring strong repellent and a head net. Summer weather is moody: expect cool mornings, mist, and muddy trails after rain.
Natural Features and SceneryMature hardwoods and hemlocks shade the three-site loop, their canopy filtering sunlight onto a forest floor carpeted with moss. The Union River runs clear and cold just steps from camp. A trout stream that draws anglers and wildlife. The surrounding Porcupine Mountains terrain is rugged, with waterfalls accessible via a short trail from the outpost and Lake Superior vistas within a short drive. The woodsy setting delivers genuine seclusion; reviewers consistently note the privacy and quiet.
