Gateway to Castell Coch, one of the most picturesque castles in Wales
Fforest Fawr is the stunning backdrop to Castell Coch, a famous castle nestled in the trees above the village of Tongwynlais.
This beautiful woodland is frequently used as a film location for productions ranging from Welsh historical dramas to children's TV programmes.
The forest has an industrial history and there are some impressive deep holes left by iron mining here.
There are two trails to the castle.
Part of the Taff Trail, a long distance route for walkers and cyclists from Cardiff Bay to Brecon, passes through Fforest Fawr.
Plans to remove infected larch from Fforest Fawr
From September 2018, we will begin a programme of work to remove approximately 4000 diseased larch trees from Fforest Fawr. This is part of a nationwide strategy to combat larch disease which has affected approximately 6.7million trees across Wales.
The work is likely to continue through to 2021. During this time, there will be some disruption to footpaths, mountain bike trails and bridleways. All closures and diversions will be clearly signposted, and published on this page and through our social media channels.
The work is being planned in two phases, so we can always keep areas of the forest open for people to enjoy, and so we can minimise the impact on protected species and local wildlife.
Read our FAQ document for more information about the felling.
