Visas & entry
Wisconsin follows U.S. federal entry rules. U.S. citizens need no visa; Canadian citizens generally do not need a visa for short tourist visits but need appropriate proof of citizenship and identity. Many other visitors need either an ESTA under the Visa Waiver Program or a U.S. visitor visa—verify current requirements before booking.
Getting in
Getting around
Use a car for any itinerary involving Door County, Baraboo/Devil's Lake, the Driftless, Bayfield or the Northwoods; public transport is not a realistic substitute for trailheads, state parks, lakes and small towns. Milwaukee is manageable without one in its core neighborhoods, and Madison is bike- and walk-friendly, but a rental car becomes useful for day trips. Amtrak serves the Chicago–Milwaukee–Wisconsin Dells–La Crosse corridor, but it does not solve the rest of the state; reserve summer and Packers-weekend rental cars early.
Money
The currency is the U.S. dollar. Cards and contactless payment work almost everywhere, but carry some cash for small-town taverns, farm stands, tips and occasional parking; ATMs are easy to find. Tipping is expected: roughly 18–22% at table-service restaurants, plus tips for bartenders, hotel staff and guides.

Eating well
Book before you land
Entry rules change — verify visa requirements for your passport before booking this region.
January–March
Expect genuine winter: freezing temperatures, short daylight, regular snow and potentially much heavier accumulation near Lake Superior.
Roads can be icy, seasonal businesses reduce hours, and Door County or Apostle Islands conditions are weather-dependent rather than reliably scenic-trip friendly.
April–May
April is volatile, while May brings green southern landscapes, revived farmers' markets and pleasant Milwaukee and Madison patios, though the Great Lakes remain cold.
Mud, wind and variable temperatures are normal, and Door County is only partly awake—check restaurant, lodging and attraction opening days individually.
June–August
This is peak Wisconsin: warm lake weather, festivals, patios, cycling, kayaking and outdoor dining, with thunderstorms and occasional heat waves.
Friday and Saturday lodging is expensive and scarce in Door County, the Dells, Lake Geneva, Bayfield and near major parks; reserve summer weekends well ahead.
September–mid-October
Warmish days, cool nights, harvest food and changing leaves make this the most reliable mixed-itinerary season.
September weekends remain busy, especially in Door County; travel midweek for noticeably calmer roads and lodging.
Late October–December
Cities remain good for museums, sports, breweries and restaurants, while rural areas turn quieter and winter conditions begin to take hold.
Door County and other rural resort areas have reduced restaurant and lodging hours, and this is not the season to expect the full summer-resort experience.
EAA AirVenture Oshkosh · Usually late July through early August · Oshkosh and the Fox Valley
One of the state's biggest accommodation distortions: rooms become scarce and expensive across Oshkosh and much of the Fox Valley. Reserve far ahead if attending; otherwise avoid using the area as a base.
Wisconsin State Fair · Usually early to mid-August · West Allis, near Milwaukee
It tightens hotel availability and adds traffic in western Milwaukee and around the fairgrounds; book early if the fair is part of the trip or base elsewhere if it is not.
Eat Wisconsin through dairy, tavern ritual and freshwater fish rather than generic Midwestern comfort food. Seek out fresh cheese curds, do one proper supper-club dinner with a brandy Old Fashioned, and time at least one Friday fish fry; then let each region supply the local specialty.
Milwaukee: Bratwurst · German beer-hall food · Frozen custard · Friday fish fry · Serious Mexican food, especially on the south side
Madison: Dane County Farmers’ Market produce and cheese picnic supplies · Farm-driven restaurants · Inventive casual dining · Good coffee between lake walks
Racine: Kringle, best bought for a group breakfast rather than treated as plated dessert
Door County: Cherry pie and cherry products · Smoked fish · Fish boil · Whitefish
Green Bay and northeast Wisconsin: Booyah, especially at church, civic and community events
Driftless region, especially Viroqua: Farm stores · Seasonal produce · Local cheese · Cider · Small-town tavern food
Central Wisconsin: Cranberry products
Northwoods and Lake Superior: Smoked trout and whitefish · Walleye · Locally caught freshwater fish
