Last long night on the water
Friday 11 September 2026 is the Hannekes end-of-summer party. Venue: Hannekes Boom, Dijksgracht 4, next to Centraal on the Oosterdok. The page promises free entry, several DJs, sunset and a party late into the night. They stay open later that evening. Which DJs, and the exact start, they will post on socials later.
Friday hours on their site run to 03:00. Treat that as a clue, not a promise for the party itself. Email: evenement@hannekesboom.nl. Phone: +31 20 419 9820.
Train or tram. A car in that pocket of the city is a headache. Same week in Noord: Cinema Culinair at Tolhuis, ferry across the IJ.
