Lon Eifion Cycleway

Lon Eifion Cycleway Overall Rating: ⭐⭐⭐⭐

Lon Eifion Cycleway is a 12.5 mile traffic-free route, running from Caernarfon to Bryncir. Offering a range of views, from rich woodland to spectacular mountains (at one point you can see Snowdon) it is cycling heaven. Disappointingly, there is no café of pub at the end, in Bryncir.

The name simply means Eifion’s Lane. The name is from the district in which the route can be found, Eifionydd. The district was named for the grandson of King Cunedda. Lon Eifion starts right by the Caernarfon train station, within sight of the castle. Do note that this is a heritage steam railway, not normal passenger services.

The surface is very good tar throughout and for significant sections it is as wide as a country lane for cars.


Lon Eifion Cycleway is usable on any bicycle.


There are toilets at Caernarfon train station, at Dinas (Welsh Highland Railway), and at the Tafarn Pennionyn (just off the trail).

Snowdon is visible (in good weather) from part of the route and you can see the Llyn mountains from other parts.

Also consider visiting Caernarfon Castle.

Routes in North Wales


There are no A-frame barriers along this route, but there are some gates. These should be wide enough for normal trikes and cargo bikes to fit through.
