Take a train Den Haag followed by a short tram ride to Scheveningen. You’ll alight next to a landmark hotel called the “Kurhaus”. In Summer, turn left from the hotel, along the promenade on the beach to find dozens of temporary pavilions where you can sit and have food or drinks. Some of these places have ‘fire tables’ which means that even if the weather isn’t great you can still sit outside. More like Ibiza than Brighton. Its great here and definitely family friendly. See also Schevening (Den Haag) for places nearby for kids.
