What campers say

Union River “Big Bear” Campground is a well‑kept, family‑friendly park ideally located at the entrance to the Porcupine Mountains with beach access across the street to Lake Superior. Sites are gravel, roomy, and often shaded; hookups include water and electric with an on‑site dump station, though some sites share a utility post so longer hoses/cables may be needed. Bathrooms are cleaned regularly with hot showers, and the small camp store offers ice and firewood. Owners are responsive and evenings are quiet. Cell service is limited and Wi‑Fi is basic; a few guests noted strict pet and refund policies—confirm rules before booking.
