Malbork is easy to reach by train from Gdańsk, with frequent services taking about 45 minutes to an hour. The town is on the main Warsaw–Gdańsk railway line, so there are also direct trains from Warsaw (about 2.5–3 hours). The train station is within walking distance of the castle — it takes about 10 minutes on foot from the platform to the castle entrance.
By car, Malbork is about 60 km southeast of Gdańsk on the S7 expressway, roughly 45 minutes. Parking is available near the castle entrance.
