01.07. - 05.07.2025 in Gifhorn
HOA25 will take place again from Tuesday to Saturday (July 1st - 5th, 2025).
The Hacken Open Air is best hacker camping, hosted by the Stratum 0. Together with you, we want to tinker, discuss and be creative in the middle of the nature.
The location will once again be the Pfadfinderheim Welfenhof in Gifhorn, close to Brunswick. Address:
Pfadfinderheim Welfenhof III. Koppelweg 6 38518 Gifhorn
We are looking forward to see you!
Infrastructure
The campsite has fixed indoor showers and toilets, and we build open-air showers. In addition, we offer area-wide electricity, DECT and Wi-Fi, so you are perfectly equipped for hacking and chilling. To chill there will probably be a pool with a sauna, as well as a directly adjacent campfire. There you can enjoy the evening with drinks at the bar.
(H)Elves
The Hacken Open Air is only possible with your help!
This year, we're trying something new and organizing our helpers offline: On-site, using a whiteboard. No prior training or special experience is required to help. Simply pick a shift and show up. At the beginning of your shift, someone will be there to explain everything you need to know.
Your help with build-up and teardown is also welcome. If you can help with build-up and teardown, you can even arrive as early as June 28th (the Saturday before the event) and stay until July 6th (the Sunday after the event)!
Generally speaking, we can only escalate as many things as there are helping hands.
Food
There is a breakfast buffet every day between 09.00 and 12.00. In the evening we will prepare dinner for everyone. Our preliminary meal-plan can be found in our Wiki.
Breakfast and dinner during the event are included in the ticket price. In between, we'll plan on offer some deep-fried food.
We have cutlery, dishes and cups that we wash ourselves, so there is no need to bring any of that.
Camping
Per person there are about 12 m² available on the campground. On average there are about 100 W of electricity per person available.
Arrival
Arrival is possible from Tuesday (July 1st) in the morning. Departure is on Saturday (July 5th). If you are willing to help with setup and takedown, you can also arrive earlier and stay longer. See the "(H)Elves" section.
There will again be a train station shuttle for arrival and departure, which you can reach call at +49 15561 601391. (Note: Number has changed!) If possible, please contact us early via text message, Signal, or call so we can schedule the trip.
For arrival by car, please use the following address:
Welfenhof Scout Center III. Koppelweg 6 38518 Gifhorn
In Gifhorn, take the Tangente road via II. Koppelweg and Barnbruchsweg. See directions map.
There are also limited parking spaces at the campground.
Day tickets
For all days (Tuesday to Friday) there are day tickets available at the box office. This entitles you to visit the HOA from 09:00 until night. One dinner is included. The ticket does not entitle to overnight stay. Day tickets cost 20 € each.
Art and decoration
We love colorful lights and would be delighted if HOA25 is as beautiful as the previous HOA. Anyone who has ideas for decorations or art installations is welcome to get involved (again).
We will be happy to answer any further questions about art and decoration at kontakt@hackenopenair.de.
Talks and Workshops
We'll be having a yurt for talks and workshops again this year. You can simply choose a slot on the wiki page Talks and Workshops and enter your topic there. The call for participation / workshops / talks is still open and will continue throughout the event.
