Matt and KJ's Yard

2 sites · RVs, Tents4 acres · Ontonagon, MI

Our almost 4 acre slice of paradise. Last stop on the Ontonagon River before Lake Superior. Public access to Lake Superior is a short walk from our yard. When there are no burn bans, you can have a fire in our fire pit. We do have some larger wood available onsite at no charge if you wish to use it. Note: There is an active factory next door that has gotten busier and can make a lot of noise. Daytime noise probably isn't too problematic but it can go on at night too. Last year we opted to not offer camp sites for this reason. This year we decided to open up but to make sure guests know the potential. It is a weld shop so the noise is usually grinding or pounding of a hammer. In warmer weather, they open the door and it can be noisy for sure...but many have said it is still quieter than where their home is. Please be sure you are okay with this before booking. They currently work 5am-3am M-Thu and then a small crew 5am-5pm Fri-Sun. Friday-Saturday and Sunday are least likely to make noise but it is still possible.

Lake Superior Beach Perfection

1 site · RV, Tent1 acre · Lake Linden, MI

What more do you need than a private camping site and your 125' of your own pristine Lake Superior beachfront access? Well, there is the need of a fire ring so we added that, too! Everything else you will to bring to enjoy the million dollar views. Oh, and on the opposite side of the camping site is quiet slough which is great for smooth water paddling and exploring. Down the gravel road about 1/3 miles are logging roads to hike, bike and explore. OHV trails are a couple miles away but check local maps for detailed information. There is a port-a-john available. You will need to bring your own firewood if you desire a campfire.

RV camping in Lake Superior guide

Overview

Along Lake Superior's shores, RV campers will find incredible forests for hiking, beaches for lounging, and RV campsites to spend the night. Summer is the most popular time to visit, when the lake is in peak form and campers can rent kayaks to paddle along the Pictured Rocks National Lakeshore—just be sure to pack the bug spray. Camping options range from large RV parks and resorts to secluded, single RV campsites on private land, so visitors can choose the campsite that works best for them. RV resorts typically draw big crowds with amenities like full hookups, dump stations, clubhouses, laundry facilities, and wifi, while individual RV campsites are quieter with picnic tables and fire pits.Although winter RVers can try snowshoeing and cross-country skiing near Houghton or go to Marquette for fat tire biking and dog sledding, they'll need to make sure the RV heater is warm enough to keep you comfy through temperatures in the teens.
