Tips for attending major music festivals in the world
If you are a music fan, you may consider attending at least one of ot the biggest music festivals in the world. But before considering any festival, check out the following tips for having a better experience:
- Book tickets early: Major festivals like Tomorrowland, Hellfest, or Glastonbury sell out in minutes. Don’t wait for the full lineup to drop. Sign up for pre-sale alerts months in advance and have your payment info saved.
- Plan accommodation well in advance: Before purchasing a festival ticket, check the surrounding area’s hotel availability or campsite rules.
- Consider extra expenses: Even the free festivals have hidden costs. When budgeting, remember to factor in locker rentals, phone charging station fees, parking passes, food, and supermarket.
- Prioritize genre over hype: Don’t go to a festival just because it’s famous. Research the sub-genres. Pick the soundscape you actually want to hear for 12 hours straight.
- Consider crowd size: Mega-festivals (200,000+ people) offer mind-blowing production, massive firework shows, and exclusive headliners. On the other hand, you should expect long lines for bathrooms, dense crowds, and miles of walking between stages. If you get overwhelmed by claustrophobic crowds, look into boutique or medium-sized regional events instead.
