One of the main forests in Mid Wales is the beautiful Hafren Forest. Named after the Welsh name for the River Severn (Afon Hafren), the source of the river lies just beyond the forest boundary. Located on the edge of the Cambrian Mountains, 6 miles (9.65km) west of Llanidloes, it was originally planted by the Forestry Commission in the 1930s for timber production. Hafren Forest has since been transformed into a popular destination for walking and wildlife spotting, making it a fantastic destination for outdoor lovers and days out with family and friends.

Hafren Forest features a range of scenic routes, including:

  • Blaen Hafren Falls Trail - a moderate walk of 3¾ miles/6 kilometres, taking around 1½ hours.
  • Source of the Severn Trail - this strenuous 8 miles /13kilometre trail begins close to the rivers source and passes a standing stone and the remains of a mine and a farmstead along the trail.
