Hidden Bike Routes in Wales: 7 Trails Even Locals Don't Know About

Wales is packed with cycling routes — the Taff Trail, the Mawddach Trail, the Lon Las Cymru. They're brilliant, but they're also plastered across every guidebook going. If you want the quiet stuff — the trails where you'll see more sheep than people — you need to dig a bit deeper. Here are seven routes that somehow keep flying under the radar.

1. The Trawsfynydd Loop, Snowdonia

Most visitors to Snowdonia head straight for Snowdon or Coed y Brenin. Meanwhile, the loop around Llyn Trawsfynydd reservoir stays remarkably peaceful. The tarmac perimeter road is smooth and largely traffic-free, with views of the Rhinogydd mountains that'll stop you in your tracks. About 12 miles of gentle riding, perfect for a lazy afternoon.

2. The Cleddau Dangle, Pembrokeshire

Running alongside the Eastern and Western Cleddau rivers near Haverfordwest, this route stitches together quiet lanes and riverside paths through deep wooded valleys. Locals know the individual sections, but very few ride the full 18-mile corridor. The stretch through Canaston Woods is especially good in autumn when the canopy goes copper.

3. The Bwlch Nant yr Arian Kite Trail, near Aberystwyth

The visitor centre is well known for its red kite feeding, but the mountain bike trails beyond the main loop get surprisingly little traffic. The Summit Trail climbs through plantation forest and opens onto exposed moorland with views right out to Cardigan Bay. At 15 miles with some proper climbing, it earns your pint afterwards.

4. The Neath Valley Heritage Route

This isn't a signed trail — it's more of a local's route piecing together old tramways and tramroad paths from the industrial era through the Vale of Neath. You'll pass crumbling ironworks, forgotten waterfalls and dense oak woodland. Start in Resolven and follow the old Melincourt branch for one of the most atmospheric rides in South Wales. Bring a basic map or GPS — waymarking is non-existent.

5. The Dyfi Forest Loop, Machynlleth

Everyone races through Machynlleth on the way to the coast or the Corris craft centre. Turn left instead and you'll find the Dyfi Forest, with miles of graded trails winding through Sitka spruce and Douglas fir. The Climach X Trail is the main draw for mountain bikers, but the gentler riverside loop along the Afon Dyfi is where the real solitude lives. About 10 miles, mostly flat.

6. The Radnorshire Radnor Ring Fringe, Mid Wales

The official Radnor Ring is a lovely 85-mile circuit, but the unsurfaced sections on its northern edge — around Llandegley Rocks and across Radnor Forest — see a fraction of the traffic. These old drovers' tracks across open hillside feel genuinely remote. Check conditions after heavy rain — the clay sections turn to glue.

7. The Dwyryd Estuary Path, Blaenau Ffestiniog to Penrhyndeudraeth

Take the Ffestiniog Railway up to Blaenau, then ride back down through the Vale of Ffestiniog to the Dwyryd estuary. The lower sections follow old railway alignments and quiet lanes with views across the tidal flats to Harlech Castle on its ridge. At 14 miles and almost entirely downhill, it's the best gravity-assisted ride in North Wales. Use the train to gain the height — why would you not?

Practical Notes

None of these routes charge entry fees, and all are accessible year-round, though the Radnorshire and Snowdonia trails fare poorly in sustained wet weather. Carry a basic repair kit, pack waterproofs even in summer (this is Wales, after all), and tell someone where you're heading on the more remote rides. Mobile signal is patchy across most of mid and north Wales.

Happy riding. Keep these ones to yourself.
