This route was planned by komoot.
The route offers a varied terrain. You'll find significant portions of well-paved surfaces and asphalt, including dedicated cycleways and sections of old railway lines converted into cycle paths. However, be aware that some coastal path sections, particularly those not specifically designated for cycling, can be rougher, muddy, or unmade, and may require brief detours onto adjacent roads if you're on a pure road bike.
You'll encounter a diverse range of landmarks and scenic spots. Highlights include the impressive Cardiff Bay Barrage, offering great coastal views, and the iconic Penarth Pier and Pavilion. You'll also get a View of Cardiff Bay from Pembroke Terrace, and pass by the historic Barry Dock Office. The route also showcases the vibrant Cardiff Bay waterfront and the dramatic coastal scenery of the Vale of Glamorgan.
While generally considered easy with mostly gentle hills, there are a couple of notable inclines. The 'wiggly path up to Penarth' is consistently mentioned as the steepest part of the ride. On the return journey, St Mary's Well Bay Road also involves an uphill section, though it's described as not overly steep.
For starting the loop from Cardiff Bay, there are various public car parks available in the Cardiff Bay area. Consider parking near the Wales Millennium Centre or the Barrage for convenient access to the start of the route.
Yes, both Cardiff and Barry Island are well-served by public transport, including train services that allow bikes (though restrictions may apply during peak hours). Penarth also has a train station. It's advisable to check specific train operator policies and timetables regarding bike carriage before you travel.
While the route largely follows cycle paths and roads, which are generally dog-friendly, specific sections of the coastal path might have restrictions or be unsuitable for dogs, especially if they are unmade or involve walking on rocky beaches. Always keep dogs on a leash, especially in urban areas, near livestock, or on shared paths.
The best time to cycle this route is typically during the spring, summer, and early autumn months (April to October). During these periods, you'll generally experience milder weather, longer daylight hours, and less chance of muddy conditions on unpaved sections. Always check the local weather forecast before heading out.
No, there are no specific permits or entrance fees required to cycle this loop. The route primarily uses public cycle paths, roads, and sections of the National Cycle Network.
Much of the route, particularly the dedicated cycle paths and well-paved sections, is suitable for families. However, some parts involve riding on quiet roads with traffic, and certain coastal path sections might be too rough for younger children or less experienced riders. Families might prefer to cycle specific sections, such as the Cardiff Bay Barrage or the Penarth promenade, rather than the entire loop.
Absolutely! You'll find numerous cafes, bars, and restaurants in Cardiff Bay at the start/end of your ride. Penarth also offers a good selection of eateries, particularly around the pier and town centre. Barry Island provides traditional seaside cafes and food stalls. It's a well-serviced route for refreshments.
Yes, the route incorporates sections of the proposed National Cycle Network Route 88. It also follows parts of the Cardiff Bay Trail and the Railway Walk, among other local paths like Ferry Lane and Cogan Hill.
