BASIL will take place on September 4th 2021 at the Garenmarkt in Leiden, from 10:00 to 18:00 as well as an online program starting at 20:00.

If you come by public transport, get off at busstop Korevaarstraat. From here it is only a short walk. Are you coming by bike? It should be easy enough to find a place to stall your bike nearby, but we ask you to please not put it on the road.

House rules

Of course we have some house rules that you have to follow so our festival can be as much fun as possible, which is why we ask you to read them. When you enter the terrain, you automatically agree to our rules.

Unlike our usual event at Matilo, BASIL is not a closed off event this year. As such, there are no bag checks this year. Still, we ask you to adhere to not bring the following things:

  • Weapons or other things that can serve as such will not be allowed
  • Fireworks
  • Perfume, deodorant, or other aerosols
  • Glass and cans (we have a beautiful terrace where you can be served drinks)
  • Hard drugs
  • Professional cameras (smaller cameras and phones are, of course, allowed)

Furthermore, we do not appreciate these actions either:

  • Destruction, theft, brawls and such. You will be handed over to the police and you will be charged for any damages
  • Handing out flyers not associated with us or any of our affiliates.

The judgment of the security crew is binding.

You can (and we encourage you to) take the following things with you:

  • Empty bottle to fill with water. Stay hydrated!
  • Raincoats
  • Warm sweater

Festival crew

BASIL is fully organized and run by volunteers. So be a little kind to us and to each other. Our crew takes care of your safety together with security and police, for example in the event of an emergency. Therefore, please follow the crew’s instructions at all times. They’re there to ensure everyone has the best possible time.


BASIL is a sustainable festival. In addition to attracting hippies, we are also organizing a festival as sustainably as possible and we need your help with that. So throw litter in the trash and throw your cigarette butts in the designated places. As you should, right?

Age check

Everyone is welcome at our festival site. To drink alcohol you have to be 18 years or older. Upon presentation of your ID card, driver’s license or passport, you can get a stamp at the entrance. This way the bar staff can easily see that you are allowed to drink. Please note that no age checks are done at the bar, so just get one of our cool stamps.


We have a media crew on the terrain. These people can photograph or film you, so don’t forget to laugh! In principle, you agree to this as soon as you enter the terrain, but if you really don’t want it, you can contact us.

All rights are reserved by the artists and performers for both sound and image. Professional cameras are not allowed, but a blurry picture for your snapchat story or insta is of course totally fine, don’t forget to tag us so that we can enjoy with you!
