What's On in Machynlleth

Every Wednesday: A Market Chartered in 1291

The oldest fixture on Machynlleth's calendar has been running for more than 730 years. In 1291 Edward I granted Owen de la Pole "a market at Machynlleth every Wednesday for ever and two fairs every year" — and the "for ever" part has held. The same charter granted two annual fairs, but it is the weekly market that has proved indestructible. Today it is run by Machynlleth Town Council, and around 50 traders line Maengwyn Street each Wednesday, roughly from morning until mid-afternoon. The town's cafes and pubs are at their busiest on market day, which makes it the perfect day to combine with our eating out guide. If you can only visit the town on one day of the week, make it a Wednesday — there's more on our market page.

Late May to August: Beer, Music and Big Ideas

Around the late-May bank holiday, the White Lion holds its annual beer festival in the pub garden — see our pubs and real ale guide for the full picture of the town's cask scene. High summer belongs to Gŵyl Machynlleth, the town's festival of classical and traditional Welsh music with talks alongside, held at the Tabernacle every late August since 1987 (2020 excepted). The former chapel's auditorium seats 350, an intimate setting for a week of concerts, and the 2026 edition runs 23–29 August — more on our MOMA and Tabernacle page. In the same week, the Centre for Alternative Technology hosts its CAT Conference from 21–23 August 2026; note that CAT operates on a pre-booked basis, so book ahead rather than turning up — details on our CAT page.

What’s changed: the lantern procession returns, the Dyfi Enduro does not

One much-loved fixture has come back and one has not. The Machynlleth Lantern Parade — the town’s long-running procession of community-made lanterns — looked finished after its November 2025 edition, when more than 2,000 people turned out and its organiser stepped down. A new volunteer committee has since taken the tradition on and relaunched it as the Bro Ddyfi Lantern Procession, with lantern-making workshops running across the Dyfi Valley through October half term; the Cambrian News reported the revival in August 2026 and the Dyfi Biosphere Partnership lists the procession as an annual October fixture. Because it is entirely volunteer-run, confirm the date locally before making a journey for it — the background is on our lantern procession page. The Dyfi Enduro, the mass-participation mountain bike event, has not come back: it last ran in 2019 and remains on hiatus, though Mini Enduro racing still visits the area, with a Machynlleth round held in July 2025. Riders will find plenty to go at year-round on our mountain biking pages.

Good Friday to October: Steam on the Corris Railway

North of town the Corris Railway runs steam trains on 2ft 3in gauge track between Corris and Maespoeth, generally from Good Friday to the end of October and generally on Saturdays, Sundays and bank holidays. Departures from Corris are advertised at 11am, noon, 1.30pm, 2.30pm and 3.30pm, the round trip takes about 50 minutes, and the railway advises pre-booking because tickets are limited. The museum alongside is free and holds original slate waggons and a restored Corris carriage. It is a volunteer operation, so a diesel sometimes stands in for steam and timings can move.

Beyond the fixtures above, the town's calendar is genuinely fluid, and small one-off events come and go through the year. For what is on in any given week the most useful sources are Machynlleth Town Council, MOMA Machynlleth's own listings and the Centre for Alternative Technology's events page; direct links are on our useful links page. At the time of writing the 2027 comedy festival dates had not been announced, though the festival has consistently taken the early-May bank holiday weekend.
