Clear, turquoise waters at Porthgwarra are often frequented by basking sharks and seals during summer months.

Porthgwarra is a remote, sheltered cove located on the Penwith Peninsula in West Cornwall. It is distinctive for its historic man-made tunnels cut through the granite cliffs, originally built to allow farmers to move seaweed and crops from the beach. The beach is accessible via a steep slipway and features a mix of sand and rock pools at low tide. It is part of the St Levan parish and sits directly on the South West Coast Path. The surrounding landscape is designated as an Area of Outstanding Natural Beauty. Its geology consists of dramatic granite rock formations typical of the Land's End peninsula. The site remains a working cove with a small number of traditional fishing boats often visible.

Check tide tables before visiting, as the beach disappears almost entirely at high tide.
Bring sturdy footwear, as the slipway is steep and the surrounding coastal path terrain is uneven.
Visit during low tide to explore the rock pools and the inner tunnel entrance.
Do not attempt to swim far from the shore due to strong currents and submerged rocks.
Keep dogs on a lead in the main car park and near livestock; adhere to local signage regarding restricted areas on the private estate.
