2000trees takes place in Cheltenham, Gloucestershire, United Kingdom, usually in July, British summer. It is a small, 10,000-capacity festival where the crowd notices what you wear, running 4 days across open field with camping on site.
Days sit around 21°C (70°F) and nights fall to 12°C (54°F), a 9-degree swing that most first-timers underestimate. Rain is likely at some point across the weekend. Combined with the ground here, that means mud, which is the single biggest factor in what you should put on your feet.
Below: the 10 outfits that work best at 2000trees, what the crowd actually wears, and the practical rules, bag size, footwear, night layers. That decide whether the outfit survives the weekend.
