Pentyrch Woods

Highlight • Forest

This is a gorgeous woodland situated at the foothills of the Garth Mountain between the two towns of Taffs Wells and Pentrych.

You'll be walking through a majestic display of ancient broadleaved woodland which is located on a boundary between two soils; acidic and calcareous. The differing soil types make for an interesting variety of fauna, including the Giant Lacewing, which is very uncommon to the area.

View of Garth Mountain from Route des Alpes

Highlight • Viewpoint

The road to the South of Garth Mountain is named the "Route Des Alpes" on Google maps. I'm thinking it isn't genuine, but I like it!

The views from the footpath climbing up off the road are fantastic on a clear day.
