Campgrounds and RV parks near Alpena, MI

The signature draw is Thunder Bay National Marine Sanctuary, which protects an estimated 116 historically significant shipwrecks offshore of Alpena. Lake Huron's cold, fresh water keeps many wrecks intact, and Alpena Shipwreck Tours runs glass-bottom boat cruises out of downtown so visitors can view them without getting in the water. On land, families gravitate to the Great Lakes Maritime Heritage Center, the sanctuary's free visitor center and museum on the Thunder Bay River. Fishing is strong on Long Lake and the Thunder Bay River for walleye, bass, pike, and perch, and paddlers can follow the Alpena Blueway along the Lake Huron shoreline. Sunken Lake Park adds hiking, swimming, and a boat launch for canoes and small boats.

The camping season around Alpena is short and clearly defined. Alpena County's camping season runs from May 15 until October 15 annually, though individual county parks such as Long Lake Park and Sunken Lake Park may close their gates earlier in October. Private parks follow a similar window: Campers Cove RV and Campground is open May 1 through October 15, with a seasonal pool and store. July and August are peak months for warm-weather activities on Lake Huron, with reliable temperatures for swimming, paddling, and glass-bottom boat tours. Late spring and early fall bring quieter campgrounds and cooler nights, and color along the inland lakes and river corridors typically peaks in late September into early October. Winter shuts most campgrounds down. January is the coldest and snowiest month, with snow falling on about 20 days on average. Alpena's climate is humid continental, with cold, snowy winters and warm summers moderated by Lake Huron, so plan RV trips inside the May-to-October window unless a park is specifically listed as open year-round.

Campgrounds around Alpena skew toward modest, functional sites rather than resort-style layouts. Sunken Lake Park offers 55 campsites with electricity, modern restrooms, showers, a dumping station, a picnic area, hiking, a playground, swimming, fishing, a boat launch for canoes and small boats, and pavilion rental. Long Lake Park lists 80 modern and 25 rustic sites along the shore of Long Lake, with a boat launch, showers, and a dumping station. Alpena County Fairgrounds is inside the city on the Thunder Bay River, with grassy sites and a walk to shared restrooms. Campers Cove offers waterfront and shaded RV sites, an indoor pool, canoe and kayak rentals, and cabin rentals. Cell coverage is generally solid in town and along US-23, thinner at the inland county parks. Pack for cool evenings even in summer, and bring bug spray in June.
