Volcano Trail

Highlights: Discover Coed y Brenin’s fascinating geological history. See spectacular views of the surrounding Meirionnydd mountains.

Distance: 7 miles, 11 kilometres

Grade: strenuous

Trail description: On this challenging circular walk, you will visit many key features in the forest, including the copper bog and the highest point of the forest park – Moel Hafod Owen. Take in the five information panels to help you explore Coed y Brenin’s violent volcanic history.

The trail is on a combination of forest roads and steep narrow paths, often less than 50cm wide in places, on an unmade, uneven surface, where you can expect mud, rocks and tree roots along some of the roughest terrain in the forest.

There are steps on the steep ascent up to Moel Hafod Owen where you will find a bench at the top for a well-deserved picnic whilst admiring the view.

If you want to experience a real adventure, ensure you go well prepared for a long day in the woods.
