Machynlleth has been a market town since 1291 and, for a few months in 1404, the seat of a Welsh parliament. It is still the place where Mid Wales does its business on a Wednesday — and the base from which to reach the Dyfi estuary, the Cambrian coast and the mountains behind them.

Two things people come a long way for
The Mach Loop carries the town’s name, in the shortened form locals and aircrew alike use. It is not an airshow and there is no timetable: it is a low-level military training route through the valleys north of here, and on a good day fast jets come through below the level of the hilltops while people watch from the hillsides above. On a bad day nothing comes at all, which is why our guide spends as much time on what to do with the rest of the day as on where to stand.
The other is the driving. The passes and mountain roads around the Dyfi are among the finest in Britain to travel slowly — Bwlch y Groes over to Bala, the Dylife mountain road east across open moorland from the town’s own doorstep, the Cwmystwyth mine road south towards the Elan Valley. Our driving routes section covers ten of them, and is candid about gradients, single-track sections and the roads that a caravan should not attempt.

Welcome to Machynlleth
Machynlleth sits at the head of the beautiful Dyfi estuary in Mid Wales, a market town of around 2,000 people at the meeting of the A487 and A489. Everyone here calls it “Mach”. It is the town with the clock — the 23.7-metre Victorian clock tower of 1874 stands at the main junction and greets you whichever way you arrive — and the town with the market: every Wednesday since Edward I granted the charter in 1291, stalls have lined Maengwyn Street.
But Machynlleth’s deepest claim is written in its stones. In 1404 Owain Glyndŵr held his Welsh parliament here and was crowned Prince of Wales before envoys from Scotland, France and Spain — which is why the town is often called the ancient capital of Wales. The Parliament House on Maengwyn Street tells that story today, free of charge, three days a week.
Modern Mach wears its history lightly. It is a creative, independent-minded town: seven free galleries at MOMA Machynlleth, the Centre for Alternative Technology three miles up the valley, a comedy festival that quadruples the population each May, and a high street of genuinely independent shops where the chains have never arrived.
The Town & Its Setting
The town lies at the heart of the Dyfi Biosphere — Wales’s UNESCO Biosphere, first designated in 1977 and expanded in 2009 to take in the whole Dyfi catchment and the coast from Tywyn to Aberystwyth. Within a few miles of the clock tower you can watch ospreys fishing the estuary at Cors Dyfi, walk the oak woods of RSPB Ynys-hir where BBC Springwatch was filmed for three years, or climb to Foel Fadian on Glyndŵr’s Way, the 135-mile National Trail that passes through the town.
Behind the main street, the free public park at Plas Machynlleth — the former Londonderry mansion, given to the town in 1948 — runs up into the hills. North of the river, the Dyfi Forest hides Corris, King Arthur’s Labyrinth and the gravity trails of the Dyfi Bike Park.
Top Attractions
Parliament House & Canolfan Owain Glyndŵr — the late-medieval town house traditionally associated with the 1404 parliament, restored by David Davies in 1906–1912, with Murray Urquhart’s striking mural of the Battle of Hyddgen and a facsimile of the Pennal Letter. Open Wednesday, Friday and Saturday, admission free.
MOMA Machynlleth — seven galleries of modern Welsh art in and around the Tabernacle, a converted chapel with a 350-seat auditorium. Free to visit, Tuesday to Saturday, and home of the Gŵyl Machynlleth music festival every August.
Centre for Alternative Technology — the pioneering sustainability centre founded in a slate quarry in 1973. Note that CAT is no longer a walk-up day attraction: since 2023 it welcomes pre-booked visits, courses and groups, so plan ahead.
The Dyfi’s mountain biking — three waymarked Mach loops ride straight out of town, the volunteer-built ClimachX trail waits in the Dyfi Forest, and Dan Atherton’s Dyfi Bike Park has made the valley a place of pilgrimage for gravity riders.
