Discovering North Wales’ Hidden Coastal Gravel

North Wales’ rugged coastline offers a playground of unmarked bridleways, ancient farm tracks, and windswept beach sands—far from the busy NCN and well-trodden road routes. In this guide, I’ll share three of my favourite lesser-known gravel loops across Anglesey, the Llŷn Peninsula, and Conwy’s coastal fringes. Each ride blends isolated sea views, varied terrain, and the freedom of truly off-road exploration. Lace up your climbing legs, pack a café stop, and let’s uncover Britain’s best-kept gravel secrets by the sea.


Logistics & Kit Recommendations

  • Getting There:
    • Anglesey: Regular ferry crossings to Holyhead (Irish Ferries, Stena Line) and direct trains via the North Wales Coast Line.
    • Llŷn Peninsula: Trains to Pwllheli or Porthmadog (Cambrian Coast Line), plus regular buses along the A499.
    • Conwy Coast: Trains to Llandudno Junction or Colwyn Bay, with easy bus links to Penmaenmawr and Conwy town.

  • Best Season: Late spring through early autumn (May–September), when the bridleways dry out and wildflowers bloom. Winter winds can carve deep ruts and expose rocky sections.

  • Bike & Tyres:
    • A drop-bar gravel bike with clearance for 38–42 mm tyres or a hardtail MTB with subdued knobbies works best.
    • I run 38 mm tubeless tyres at around 30 psi front / 32 psi rear for a balance of comfort and corner-biting grip.

  • Navigation: GPX files loaded onto a handlebar GPS or phone. A compact OS map (114 for Anglesey; 124 for Llŷn; 115 for Conwy) is invaluable when tracks vanish.

  • Café & Fueling: Every route notes a mid-ride café or pub. Carry enough gels or bars for the remote middle sections.


Route 1: Holy Island Coastal Bridleway Loop

Route Rating
• Scenery: 5/5
• Challenge: 3.5/5

Overview
• Distance: ~35 km
• Elevation Gain: ~600 m
• Terrain: Coastal bridleways, disused quarry tracks, farm lanes, short asphalt link-ups

Highlights

  1. Holyhead Breakwater & Country Park: Start at the Breakwater Café, ride the old quarry road before the prom.
  2. South Stack Vista: Climb a rough farm track to the clifftops for lighthouse views.
  3. Porth Swtan (Church Bay): Drop into the pebble beach via a steep grassy bridleway; peer across to the little tidal church of St Cwyfan.
  4. Stanley Embankment “The Cob”: A 1.2 km stretch of raised causeway linking Holy Island to Anglesey proper.
  5. Trearddur Bay Return: Smooth forest tracks in the Buried Forest, then coastal road into town.

Detailed Route

  • From Holyhead Train Station, head north on the country park track, keeping right at the quarry spur.
  • Climb out of the park on a gravel farm lane to Mynydd Twr car park, then pick up the grassy bridleway north toward South Stack.
  • After soaking in the cliffs, retrace briefly then swing east on a faint track along the high sea wall toward Porth Swtan. Descend via the rutted grass to the pebble beach—beware sea spray on the steps.
  • Remount and head inland, linking onto the old RAF service road through the dunes, then onto “The Cob” embankment—a flat but exposed gravel that rewards with miles-long sea views.
  • On Anglesey side, follow fire road signs toward Trearddur Bay, cruise the sandy singletrack through Buried Forest, then finish along the seafront path back to town.

Final Thoughts & Community Rides

North Wales’ coast is dotted with unrecorded byways and bridle paths just waiting for gravel bikes. These three loops scratch the surface—every headland, estuary, and disused track deserves a carpet of tyre marks. If you ride one of these, drop your GPX in the Carter’s Cafe Spin Strava group and join me every Wednesday at 6 pm GMT for our east-coast group spin, where we tackle a surprise gravel gem each week.

Happy exploring, and may your gravel stays fresh and your horizons endless! 🚴‍♂️
