The camp is built by and for volunteers from across all corners of the international hacker community. Every edition brings together over 3,750 hackers from around the world. At its core, the event thrives on knowledge sharing, technological exploration, hands-on experimentation, and forging connections with fellow hackers. And, of course, hacking in all its glorious forms. Throughout the camp, you'll find hundreds of talks, workshops, and activities—each an opportunity to learn, build, break, and rethink the boundaries of technology.

WHY2025 is an international non-profit outdoor hacker camp/conference taking place in the Netherlands in the summer of 2025, August 8-12.

It is the successor of a string of similar events happening every four years: GHP, HEU, HIP, HAL, WTH, HAR, OHM, SHA and MCH.
