Nine Minnesota rest areas shut down for the season this fall, four of them in late September. If your route north or east runs through the Arrowhead or the lake country after that, plan on those stops being gone.
MnDOT publishes the list on its rest areas page, read August 23, 2026. The nine seasonal sites, with the operating windows the state gives them: Big Sandy (mid-April to late September), McGregor (mid-April to late September), Ottertail Lake (late April to late September), Sauer Lake (late April to late September), Cross River (late April to mid-October), Cut Face Creek (late April to mid-October), Independence (mid-April to mid-October), Knife River (early April to mid-October), and Mt. Josephine (late April to mid-October).
The problem with that list
Read those windows again. Not one of them is a date. “Late September” is a nine-day range at best, and the difference between the 22nd and the 30th is the difference between a bathroom and a locked door at 11 p.m.
MnDOT knows this, which is why the same page points you at 511mn.org for the current status of each rest area. That is the right move and we would rather a DOT say “check the live feed” than publish a firm date it cannot hold to. It also means the published list is a planning tool, not a schedule. Do not build a night around one of these nine without checking status the day you drive.
The other thing MnDOT will not do for you
There are no dump stations. MnDOT’s about page says it in one line: its rest areas do not offer dumpstation services. That is statewide. Minnesota is not a state where you route a tank dump through a rest area, and it is a useful contrast with the two western DOTs that do publish station lists, which we covered in Oregon and Washington publish rest area dump station lists.
What you can actually use a Minnesota rest area for
A short stop. MnDOT’s policy page sets the limit at four hours where posted for general motorists, and up to ten hours for commercial drivers subject to federal hours of service rules under 49 CFR 395, at sites with stalls built for a commercial vehicle. An RV or a van is a general motorist. Four hours is a nap, not a night.
So the honest verdict for anyone crossing Minnesota this fall: treat the nine seasonal sites as closed from late September, do not count on a dump anywhere in the state’s rest area system, and if you need real sleep, find land where sleeping is allowed rather than stretching a four-hour stop.
The posted sign at the site is still the rule that gets enforced, whatever any website says. Our per-state summary and the source we verified it against are at Minnesota rest area rules.
