I took my 16 year old niece last year to Top Hill, but she was dressed to impress and nobody asked for a ID, we had no problems, but I am not sure what the legal age to get into clubs is. Maybe some local expert can chip in
I have another question. Do you need to buy the tickets in advance or you can just buy at the entry?
The ticket is usually €5 which you can just purchase at the door, it is a big place that does not sell out. No worries
No Alex, for this concert presale is 8 euro, sale is 10 euro. You can read info on a web site link.
What is happening on Tuesday?
