Gniezno, 30 minutes by train from Poznań, is the first capital of Poland and the seat of the country's oldest cathedral, with regional Greater Poland restaurants around its medieval Rynek.
Tip: Combine a cathedral visit with lunch at one of the Rynek bistros; the gęsina (goose) on Sunday menus is the seasonal hit.
Kórnik, 25 km south of Poznań, is a Greater Poland market town built around a neo-Gothic castle with one of Europe's oldest arboretums and lakeside Polish bistros.
Tip: Eat at a lake-side bistro after the castle; the smoked-fish plates from Kórnik Lake are the local pick.
Rogalin, 25 km south of Poznań, is the Raczyński family palace and the 800-year-old Lech, Czech and Rus oaks, with a palace bistro pouring Greater Poland classics in restored stables.
Tip: Pair Rogalin with Kórnik; both sit within 10 km of each other and split a Sunday well between two regional lunches.
Biskupin, an hour from Poznań, is Europe's most complete Iron Age archaeological park with a reconstructed Lusatian-culture settlement and a September archaeological festival featuring period food.
Tip: Visit during the September Archaeological Festival; period-correct cooking demos on open fires are the main reason to go.
