In spring, we gather again around to welcome the first rays of sunshine and dance ourselves out of hibernation in the fresh forest air.
The Hai in den Mai festival is the annual start to the open-air psytrance season!

There is a €10 waste deposit per ticket, which you will get back after the festival when you return a full waste bag. One euro of the ticket price goes directly to the PsyClean crew.
Personalization
All tickets are personalized. After you have ordered and paid for your ticket, you can enter the name of the person who will use the ticket in the ticket shop under “My Tickets“. The name of the ticket can only be changed once. If you have received a ticket and want to check it for validity, you can do so by entering the code here that appears at the top of the ticket next to your name.
Transfer of tickets
The name on a ticket can be changed once. Under “My Tickets” you can get a new ticket with a new name.
Day tickets
This year, we will once again be offering a strictly limited number of day tickets for Friday and Saturday. These tickets will only be available two months before the festival, starting in March. Sunday tickets will also be available again.
Car ticket
If you want to park your vehicle, whether car, van or motorhome, on the campsite, you must also purchase a car ticket. The tickets are limited because we only have a limited amount of space available. If you arrive by car but don’t want to use it on the campsite, you can park it in the parking lot for a fee of €10.
Reduction
Wheelchair users with a disability card do not have to pay admission for an accompanying person.
The Warm-Up Party starts at 6 pm on Thursday on the Backyard Floor at 7 pm on the Hill Top and at 9 pm in the Club.

At Hai in den Mai, four floors once again open this year for a journey through the different styles of psychedelic music. From straight driving to experimental, from warm groove to a clear edge.
The Main Floor is the biggest stage and the center of the night: different psytrance genres meet here. At Hill Top, things get a bit more experimental and playful, while the Backyard Floor tempts with alternative techno and cross-genre sounds. And in the Club, the program deliberately remains diverse: proggy, tekno and drum & bass alternate on the different days.

Butterfly Effect – Decorations
Main Floor
Behind the name Butterfly Effect – Decorations stands the Swiss artist André Halti (*1996), whose textile art has a lasting impact on the atmosphere of events. Since 2015, he has been designing impressive decorations that transform rooms and stages into magical worlds and turn events into unforgettable experiences.
With a combination of skilful fabric design and creative vision, André cuts and sews various fabrics together to create large-scale images or unusual shapes. These flexible installations manage to temporarily lift any space into a new dimension – from dance floors to gigantic festival stages.
Butterfly Effect – Decorations stands for the art of creating temporary dream worlds that awaken imagination and inspiration. With a perfect blend of craftsmanship and aesthetic flair, André Halti creates immersive visual experiences that connect people across all borders.
Optic Noise, Abstract Architects, SleeplessOptic Noise has been a decoration team for 15 years now. They are among the pioneers in the field of spandex art for psytrance parties and have a lot in stock, from brightly fluorescent to naturally earthy color combinations. Whether hand-painted backdrops, full-surface, thousandfold perforated elements – from small to large, there is a lot in their repertoire for indoor and outdoor events. During and after COVID, Optic Noise and the Synaptic Eclipse team were quiet for 4 years. After good cooperation in the past and last year, the two are now merging into one project and will present parts of their new concept for the first time at Hai in den Mai.
Abstract Architects are an amalgamation of artists and craftspeople from the BPM Collective and will make their debut with a unique stage project for the Hilltop at the Hai in den Mai Festival 2025 in Waldfrieden. The concept is still top secret. But we can reveal this much:
Inspired by nature, we are focusing on earthy colors, wood, upcycling and natural materials. With experience from projects such as the wooden mushroom installation (Wonderland Festival 2024) and the BPM Bar at Hilltop (Hai in den Mai 2024), our team, consisting of local scene people, brings art and craft together. The original design was created by artist Jonny Lakämper – and is now being realized together as a team to give visitors an unforgettable, psychedelic dance experience.
The whole experience is supported with mapping by Sleepless.
SCHWARZER PLATZ
This year, the Schwarzer Platz (“Black Square”) will be designed by multiple artists for the first time.
Perplexity of Infinity will be showing string art objects and designing parts of the site.
Sauvage Cicada will enrich the exhibition with her fabulous paintings and screen prints.
Mushroom Vision plants small metal mushrooms for a good cause.
Ocular Scope can be watched live painting.
In the Healing Area by the lake, you can take part in spiritual programs. There are also many lectures and workshops on the topic of spirituality.
Before the festival you can find a detailed overview of this year’s program here.
We look forward to seeing you!
You can only enter the festival if you are over 18 years of age with a valid identity card or passport. Juvenile minors are not allowed on the festival, unless they they are with their parents. Unfortunately we can not provide family camping so we do not recommend you to bring your children!
Awareness
In Waldfrieden there is no place for racism, sexism, homophobia or any discriminatory behaviour and hateful ideology. This of course also means that nazis are not welcome here. Look out for each other. Those who do not respect these rules are kicked out, for example men who harass women.
Photographs
To have enough room for dirty, tired and happy faces on the festival that will not appear on the internet please do not to take pictures of others without permission. There will be professional photographers taking pictures that will be uploaded here. If you appear on a picture against your will let us know and we will remove it.
Apart from the fact that other people may not want to be filmed or photographed by you, you don’t do yourself a favor if you want to capture everything on camera. The festival is a good time to put your smartphone aside and take a vacation from the digital world. Keep the good memories in your heart – not on a chip!
Ecology
It is our desire to limit the damage to nature as much as possible. Therefor all of our electricity is supplied by renewable energy sources and we ask the food shops to sell organic food only.
Please help us to also keep the direct environment of the Waldfrieden clean by using garbage bags and pocket ashtrays. Also please use the toilets instead of going in the forest or elsewhere for that purpose.
Dogs
Dogs are not allowed on the area. Unfortunately we can not allow you to bring your dogs due to spatial conditions of the nature reserve and the animals that live here.
Laser pointers, Graffiti & Confetti
Laser pointers must not be taken with you because of the high risk of injury. Graffiti, markers and confetti may not be brought to any of our events! It is simply too much work to get rid of the garbage and paintings. Confetti also causes unnecessary environmental pollution. If you are interested in participating as graffiti artist you are welcome to apply and contact us. However, it is not permitted to bring spray cans and markers with you without permission. In no circumstances may weapons of any kind be brought to the festival!
