Oh Walmart, I have such conflicted feelings about you. I do not love your uber-big box, take over the world, pay your employees crap nature BUT you are one of the few reliable spots to “camp” for free. Check out All Stays for a list of Walmart stores that allow RV parking. Overall company policy allows for RV parking but it’s up to the discretion of the store manager.
We have checked out quite a few Walmart parking lots in our roaming but our favorite by far is the Walmart parking lot in Moscow, Idaho. Twice a year we head to work at the University of Idaho and the Moscow Walmart is a five minute drive from campus. The biggest plus is that it has a large side lot that is perfect for RV parking with a lovely view overlooking the campus and the rolling hills of the Palouse. Every other time we have had the place to ourselves so imagine our surprise when we pulled in at midnight and there were two other RV’s parked there! There was plenty of room, as you can see from the pics.
Most other Walmarts we have stayed at have been on major highways or in major cities so it’s usually a mix of semi-truck, RVs and people sleeping in their cars. It can seem a bit sketchy but it is a great option if you are looking to save some money and just need a spot to sleep on your way to an epic location.
