1. What to do
Start in the old centre, around the Plein and the Hofvijver pond. The Binnenhof is the medieval complex where Dutch politics has sat for centuries, with the Ridderzaal (Hall of Knights) in the middle. Since 1 October 2021, the Binnenhof has been under renovation. Access is therefore restricted, and the inner courtyard cannot be freely visited. During the renovation, the Tweede Kamer (House of Representatives) sits temporarily at Bezuidenhoutseweg 67, near Centraal Station, and the Eerste Kamer (Senate) and the Council of State at the Lange Voorhout. ProDemos, the House for Democracy and the Rule of Law, runs guided tours of the temporary parliament. Check with ProDemos what is possible on the day of your visit.
On the Plein itself stands the Mauritshuis, in a seventeenth-century town palace on the Hofvijver. The museum shows Dutch painting from the Golden Age, including Vermeer's Girl with a Pearl Earring and work by Rembrandt. On the Lange Voorhout, within walking distance, is Escher in Het Paleis, with work by graphic artist M.C. Escher in a former winter palace. The Kunstmuseum Den Haag shows modern art, including work by Mondrian. A few streets away stands Panorama Mesdag: a single round painting of Scheveningen in 1881 that surrounds you completely. It is the oldest panorama still on show in its original setting.
On the other side of the centre, towards Scheveningen, stands the Peace Palace on Carnegieplein. The building houses the International Court of Justice and the Permanent Court of Arbitration. It is a working court building, not an ordinary museum: visitors can go to the visitor centre. Check the Peace Palace site for what is open.
In Scheveningen itself, everything starts at the beach. Scheveningen is an old fishing village that grew into a seaside resort, with a wide sandy beach, a boulevard, a pier and the Kurhaus as its landmark. Muzee Scheveningen tells the story of the fishing village and the resort, and Museum Beelden aan Zee, near the Kurhaus, is devoted entirely to sculpture. For children there is Madurodam, the miniature park with Dutch buildings and landscapes at a scale of 1:25, on the edge of Scheveningen.
For a quieter beach, go to Kijkduin, Den Haag's second beach on the west side of the city. The beach there is wider and quieter than in Scheveningen, with dunes to walk in and beach pavilions along the boulevard. Between the centre and the coast are parks and dune areas, such as the Westbroekpark in the Scheveningen district, where you can walk without leaving the city.
End a day in the city on the Plein, the Grote Markt or the Lange Voorhout, where the centre's terraces and cafés are. Those are also the streets where you get to know the old city best on foot.
