Small town useful for a rail day trip, especially for the open-air museum, market-square area and food stops. A good bad-weather alternative to lake activities.

Muzeum Budownictwa Ludowego – Park Etnograficzny w Olsztynku
Large open-air museum with rural architecture from Warmia, Masuria, Powiśle and Lithuania Minor. Allow at least 1½–2 hours, more during seasonal events.
Muzeum Bitwy pod Grunwaldem
Museum, ruins of a post-battle chapel, monument hill and fields connected with the 1410 Battle of Grunwald. A good half-day trip from Ostróda.
Lake-resort village and forest area. Good for a beach day, woodland walk, cycling, kayaking, accommodation outside Ostróda or a trip combined with a cruise through lakes and locks.
Rural area near the Szeląg lake system. Useful for agritourism, cycling and quieter accommodation outside the town.
Jezioro Francuskie
Small forest lake on walking routes in the Dylewskie Hills. It is a walking destination rather than a normal bathing beach.
Plaża miejska nad Jeziorem Sajmino
Another useful bathing area in Ostróda, away from the main Lake Drwęckie promenade. Good for a short beach trip when the central waterfront is crowded.
