WHY2025 is a nonprofit outdoors hacker camp taking place in Geestmerambacht, the Netherlands (approx 42km North of Amsterdam), on 8-12 August 2025. The event is organised for and by volunteers from the worldwide hacker community. Knowledge sharing, technological advancement, experimentation, connecting with your hacker peers, forging friendships and hacking (everything from computers to food) are at the core of this event.
WHY2025 is the successor of GHP, HEU, HIP, HAL, WTH, HAR, OHM, SHA, and MCH making it the tenth event in the series, continuing the quadrennial hacker camp tradition in The Netherlands since 1989, a proper milestone!
This is What Hackers Yearn 2025!

The Irish grouping of hackerspaces/makerspaces and wider community are travelling to the camp and will form a village aka the Irish Embassy. You will find us in the larger Milliways Cluster. Find out more about us on the wiki, drop by or follow our Masdadon account.
