Where it is

The circle shows the general area, not the exact start. Use the directions link below to get to the car park itself. Contours and paths shown are OpenTopoMap, drawn from OpenStreetMap data.

The route

A path climbs through the park onto the Caerphilly ridge, returning along the ridgeway and down through the woods.

Worth knowing

  • The rhododendrons and azaleas in the park are at their best in late May.
  • The ridge path links east towards Caerphilly Common for a much longer walk.
  • Easily reached by train, which is unusual for a hill walk.

What you’ll see

The park’s plantings, woodland, and Cardiff and the Channel from the ridge.

Background

The park was laid out by a Great Western Railway engineer in the 1920s on land beside the Caerphilly tunnel.
