By Train -- There are frequent trains from Copenhagen (trip time: 50 min.).
By Car -- Take E-4 north from Copenhagen.
By Ferry -- Ferries ply the waters of the narrow channel separating Helsingør (Denmark) from Helsingborg (Sweden) in less than 25 minutes. They're operated around the clock by Scandlines (tel. 33-15-15-15; www.scandlines.dk), which charges DKK42 ($7.20/£4.20) each way for a pedestrian without a car, and DKK275 ($47/£28) each way for a car with up to nine persons inside. Between 6am and 11pm, departures are every 20 minutes; 11pm to 6am, departures are timed at intervals of 40 to 80 minutes. The process is simple and straightforward: You simply drive your car onboard and wait in your car. Border formalities during the crossing between Denmark and Sweden are perfunctory, and although you should carry a passport, you might not even be asked for it.
The tourist office, at Havnepladsen 3 (tel. 49-21-13-33; www.visithelsingor.dk), is open Monday to Friday 10am to 5pm, and Saturday 10am to 2pm; June 20 to August 31 Monday to Friday 10am to 5pm, and Saturday 10am to 3pm.
