Winter's End is a multi-day indoor rock festival at Trecco Bay Holiday Park in Porthcawl, run at holiday-park scale rather than as an outdoor arena event.
The audience is strictly over 18s. The format centres on standing indoor sets, accommodation units, on-site food and drink, and park leisure facilities between bands.
The festival began in Dorset in 2017 and moved to Trecco Bay in 2023. Its current site uses the Showdome event space and holiday-park facilities instead of camping pitches.
