Mountain Ash New Year's Eve 2026-2027: Parties, Club Nights & Nos Galan

Welcome to New Year's Eve 2026/2027 in Mountain Ash

Mountain Ash in the Cynon Valley, Wales, rings in 2027 with a programme that stands apart from ordinary New Year's Eve events. At its heart are the traditional Nos Galan Road Races in the town centre, held every year on the last night of the year. This guide covers what to expect in Mountain Ash and nearby on 31 December 2026 and into the early hours of 1 January 2027, and where party and club night plans are still unconfirmed.

Program & Schedule: Where to Celebrate New Year's Eve in and around Mountain Ash

The highlight of the evening is the Nos Galan Road Races. The official 2026 timetable had not been published at the time of research; in previous years the programme began in the early evening with the children's races, followed by the elite races and the fun run. Registration for runners opened on 14 September 2026, and places usually go quickly. If you only want to watch, no ticket is required.

We have not yet been able to confirm any specific New Year's Eve parties, disco nights or club nights in Mountain Ash itself for 31 December 2026. Mountain Ash is a small Cynon Valley town, and local pubs and clubs often announce their plans close to the date. Jacs Venue in Aberdare (Wind Street, CF44 7LL) also had no New Year's Eve event listed at the time of research; its regular Friday and Saturday programme of live music and disco nights runs through December 2026. We will update this page once parties are officially announced.

For a classic New Year's Eve dinner, The Vale Resort in Hensol (Hensol Park, CF72 8JY) offers a Laurent Perrier Gala Dinner to ring in 2027, currently from 199 pounds per person (around 230 euros). No detailed running order was listed.
