Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + The Missouri River finally sheds its winter ice, so the riverboats and paddlewheel cruises start running again, their steam whistles echoing across the brown water. Spring has returned. The sound carries for miles.
- + Bismarck's parks, like Sertoma and Pioneer, explode with the scent of fresh-cut grass and lilacs, and the cottonwood trees along the riverbank finally get their leaves. You can smell the season shift.
- + It's the shoulder season before the summer tourism rush, so you can get a table at the old-school supper clubs without a two-hour wait. Walk right in. Order the walleye.
- + The prairie comes alive with the sound of meadowlarks and the sight of pasque flowers, North Dakota's state flower, blooming in the hills west of town. Tiny purple stars. Worth the drive.
Considerations
- − That 'variable' condition is a genuine gamble. You could have a 70°F (21°C) day of perfect sunshine followed by a 45°F (7°C) afternoon where a cold rain whips in off the plains. Pack smart.
- − The wind hasn't gotten the memo that it's spring. It's the kind of persistent, steady prairie wind that'll turn a pleasant walk across the Capitol grounds into a battle with your jacket. Hold on tight.
- − A lot of the big summer festivals and outdoor concerts haven't started yet, so the nightlife is still mostly confined to the handful of downtown bars and the casino. Quiet nights. Good for conversation.
Best Activities in May
Top things to do during your visit
Missouri River Paddlewheel Cruises
May is the sweet spot for this. The river is high from the spring thaw, the air is finally warm enough to stand on deck, and the cruise boats have just started their season, so they're not yet packed with summer tourists. You'll smell the diesel and river water, feel the deck vibrating under your feet, and see the Bismarck skyline from a perspective you can't get anywhere else. The sunset cruises in particular are worth it, with the golden light hitting the capitol building.
Booking Tip: Boats typically start daily runs in early May. It's wise to book a day or two ahead, for weekend sunset slots. Check the booking widget below for current schedules and operators. Look for vessels with indoor/outdoor seating to handle any surprise chill.
Lewis & Clark Riverboat Tours
This is the historical counterpart to a simple cruise. The guides here tend to be passionate, weaving tales of the Corps of Discovery's winter at Fort Mandan, which is just upriver. The sound of the narration cutting through the wind, the feel of the sun on your face one minute and a cool river breeze the next - it feels like the first real outing of the year. May means you avoid the peak summer heat that can make the lower decks feel stuffy.
Booking Tip: These narrated tours are popular with school groups in late spring. Aim for a mid-week or late afternoon departure to avoid the crowds. See the booking section for current tour times and themes.
State Capitol Grounds Walking Tours
The 19-story art deco capitol could fairly be called a 160-acre (65-hectare) park. In May, the grounds are green but not yet crowded, and the air carries the clean, damp smell of sprinklers on the vast lawns. You can walk from the WWII-era Liberty Memorial Building, past the governor's residence, and up to the capitol steps without seeing another soul. The interior is all polished limestone and echoing hallways, a stark, cool contrast to the prairie outside.
Booking Tip: Free guided interior tours run regularly on weekdays. No need to book ahead, just show up. For a self-guided grounds tour, pick up a map from the visitor desk. The best light for photos of the building's facade is in the late afternoon.
Fort Abraham Lincoln State Park Exploration
This is where Custer left from. The park, about a 15-minute drive south of Bismarck in Mandan, is at its most evocative in May. The reconstructed military post and Mandan earthlodges are surrounded by greening grass, and the Missouri bluffs look less bleak. You can hear the wind whistle through the cottonwoods and smell the woodsmoke from demonstration fires. The crowds that come for summer reenactments aren't here yet, so you have the place mostly to yourself.
Booking Tip: The park is open year-round, but the onsite museum and guided tours of Custer's House operate on a more limited schedule until Memorial Day. Check the state park website for May hours before you go. Wear sturdy shoes. The paths can be muddy from spring melt.

What's happening during your visit
Mid May
Bismarck Marathon & Half Marathon
This could fairly be called the city's first major outdoor gathering of the year. The energy is palpable - a mix of nervous excitement and sheer relief that winter is over. The course winds along the Missouri River, so spectators can post up with coffee and watch the runners with the water as a backdrop. The best spot is near the finish line at the Capitol grounds, where you can hear the announcer and the cheers.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
Locals head to the Blarney Stone Pub on a chilly May evening. It's a proper Irish pub that's been there for decades, and the dark wood and Guinness taste the same whether it's -20°F or 60°F outside. Order the stew.
For a true Bismarck meal, skip the chains and find a supper club. Look for places with 'Lounge' in the name that have been around since the 70s or 80s. They serve prime rib, walleye, and stiff old-fashioneds in dimly lit, wood-paneled rooms. Time travel. Delicious.
The best way to experience the Missouri isn't always on it. Drive across the river to the Mandan side and walk the path at Fort Lincoln State Park for the postcard view of Bismarck's skyline. Bring your camera.
If you see cars parked along a rural road just west of town, pull over. Someone has spotted wild prairie crocus or pasque flowers. Locals stop everything to admire the first blooms of the season. Worth it.
Avoid These Mistakes
Packing like it's summer. That 67°F (19°C) high is deceptive. Evenings and windy days will have you reaching for every layer you brought. Pack rain gear.
Assuming everything is open. Some seasonal attractions, smaller museums or tour boats, might still be on their limited 'spring hours' until Memorial Day weekend. Check first.
Underestimating distances. Bismarck feels compact. The Capitol, the riverfront, Fort Lincoln are spread out. You'll want a car.
