Treen Cliff

Treen Cliff is a coastal cliff along the Penwith Peninsula featuring steep rock walls that rise directly from the Atlantic Ocean. The site encompasses a large area where geology and marine ecosystems meet at the water's edge.

The area was inhabited since prehistoric times, as evidenced by Treryn Dinas, an ancient cliff fortress with multiple ramparts located on this site. This settlement demonstrates how people adapted to and used the coastal landscape long ago.

This cliff edge forms part of the Cornwall Area of Outstanding Natural Beauty, reflecting how local communities value this stretch of coast as a natural landmark. The dramatic rock formations shape how people experience and connect with the Cornish shoreline.

The site is reached via coastal walking paths that connect from parking near Porthcurno beach, making it accessible for most visitors. The routes are generally well-marked and lead to various viewpoints along the cliff edge.

The site is home to rock sea lavender, a rare plant species that grows only on this specific stretch of the Cornish coast. This specialized plant thrives in the harsh conditions of the cliff face and attracts botanists and nature enthusiasts.
