Glastonbury Festival

Glastonbury Festival anchors the top spot with 210,000 attendees each June, more than any other UK festival. Its 100+ stages host over 3,000 performances, from pyramid-stage headliners like Radiohead to avant-garde circus acts. Compared to #4 Primavera Sound’s curated bookings, Glastonbury’s programming is less predictable but more diverse, spanning 12 genres per day. The festival donates £2 million annually to charities, outpacing #2 Coachella’s social initiatives. Since 1970, it has maintained a carbon-neutral policy, a benchmark for 90% of competitors. Self-expression thrives in the Green Fields, where 40% of attendees volunteer, reinforcing its reputation as communal rather than commercial.
