The Llyn Brenig Trail- Around Llyn Brenig Details

The Llyn Brenig Trail takes you all the way around Llyn Brenig, by foot or on two wheels. If you fancy an easy mtb route that’s not overly technical, with a few bits of easier going roads then this is an ideal route. Starting off at the Llyn Brenig Visitor Centre, you follow minor roads, forestry trails and cross moorlands in a route that takes you, as you may have gathered from the name, around the lake! Make sure that the distance is one you can manage as there’s no short cuts on this one.

There’s also a little bit of climbing involved so it’s not totally flat all the way so you’ll have plenty of variation for a straightforward route.

  1. I covered this route in the summer with my wife and young daughter in a bike trailer. Nice gentle ride with the only exertion really being the bit where you have a short climb on the the B4501 road .Don’t be put off by the fact that maybe a mile of the route is on a B road……we never seen one car whilst we were on it! The majority of the route is double track or surfaced/tarmac and can be completed easily, in less than two hours and would be ideal for families.
    You also have the added bonus of the visitors centre where you can grab a brew etc,
