Cornwall, with its 300 miles of coastline, offers some of the most spectacular coastal walks in the United Kingdom. The Cornish section of the South West Coast Path winds its way around rugged cliffs, golden beaches, hidden coves, and picturesque fishing villages. Whether you're an experienced hiker looking for challenging terrain or a casual walker seeking gentle strolls with breathtaking views, Cornwall's coastal paths have something for everyone.

In this guide, we'll explore some of the most stunning coastal walks in Cornwall, from popular routes to hidden gems, along with practical information to help you plan your perfect walking adventure.

The South West Coast Path: An Overview

The South West Coast Path is England's longest waymarked long-distance footpath and a National Trail. It stretches for 630 miles, from Minehead in Somerset to Poole Harbour in Dorset, with the Cornish section making up nearly half of the entire route. The path offers unparalleled views of the Atlantic Ocean and English Channel, passing through Areas of Outstanding Natural Beauty, heritage coastline, and numerous Sites of Special Scientific Interest.

The path is generally well-marked with the acorn symbol of the National Trails, making navigation relatively straightforward. However, the terrain can be challenging in places, with steep ascents and descents as the path dips into river valleys and climbs up cliff tops.

Best Coastal Walks in North Cornwall

Tintagel to Boscastle (5 miles)

This moderate walk connects two of North Cornwall's most characterful villages while offering dramatic views and legendary connections. Starting at Tintagel Castle, the reputed birthplace of King Arthur, the path follows the rugged coastline with its dark volcanic rock formations and deep, wave-cut chasms. The route passes through wildflower meadows, alongside vertiginous drops, and ultimately descends into the charming harbor village of Boscastle with its witchcraft museum and sheltered natural inlet.

Highlight: The Rocky Valley, a deep, fern-filled gorge with ancient rock carvings, is a magical detour just off the main path.

Padstow to Constantine Bay (7 miles)

Beginning in the foodie haven of Padstow, this relatively gentle walk takes you around the Trevose headland, passing a series of beautiful golden beaches. From Padstow harbor, the path climbs to offer views across the Camel Estuary before continuing to Stepper Point with its distinctive daymark tower. The route then leads on to Trevone Bay, Harlyn Bay, and finally Constantine Bay with its excellent surfing conditions.

Highlight: The Round Hole at Trevone, a collapsed sea cave forming a near-perfect circular hole in the cliff top.

Best Coastal Walks in West Cornwall

St Ives to Zennor (6 miles)

This challenging but rewarding walk is considered one of the toughest sections of the South West Coast Path. Setting out from the artistic town of St Ives with its Tate gallery and golden beaches, the path quickly becomes rugged as it climbs along granite cliffs that have been battered by Atlantic storms for millennia. The views are spectacular, with the possibility of spotting seals, dolphins, and even basking sharks in season. The walk ends in the tiny village of Zennor, home to the famous mermaid chair in St Senara's Church.

Highlight: Seal Island, visible from the path, where Atlantic grey seals can often be spotted basking on the rocks.

Porthcurno to Land's End (4 miles)

This iconic walk takes you to the westernmost point of mainland England. Starting at Porthcurno Beach with its almost tropical-looking azure waters, the path climbs past the clifftop Minack Theatre, an extraordinary open-air venue carved into the granite cliff. Continuing along the rugged coastline, you'll pass the beautiful sandy cove of Porthgwarra before reaching Land's End with its famous signpost and spectacular views towards the Isles of Scilly.

Highlight: The Logan Rock, a finely-balanced 80-ton granite boulder that can be rocked by applying force in exactly the right place.

Best Coastal Walks in South Cornwall

Lizard Point Circular (5 miles)

The Lizard Peninsula is Britain's most southerly point and offers a diverse range of coastal scenery. This circular walk takes you around the Lizard headland, starting and ending at Lizard village. The path passes Lizard Point lighthouse, then continues along dramatic cliffs with their distinctive serpentine rock formations. The route passes Kynance Cove, considered one of the most beautiful beaches in Britain, with its white sand, turquoise water, and towering rock stacks.

Highlight: The stunning geological formations at Kynance Cove, which are especially beautiful at low tide when you can explore the interconnected caves and islands.

Falmouth to Helford (10 miles)

This longer walk showcases the gentler side of Cornwall's coastline, taking in the sheltered waters and woodlands of the Helford River estuary. Starting in the bustling port town of Falmouth, the path winds through Swanpool and Maenporth beaches before climbing through ancient oak woodland at Rosemullion Head. As you approach the Helford River, the landscape becomes increasingly lush and subtropical, with the famous gardens of Glendurgan and Trebah nearby. The walk ends in the pretty village of Helford, accessible by seasonal ferry from Helford Passage.

Highlight: Durgan, a secluded fishing hamlet on the north shore of the Helford River, with its peaceful beach and historic cottages.

Hidden Gems: Lesser-Known Coastal Walks

Pentire Point to Pentireglaze Haven (3 miles)

Often overshadowed by the popular Bedruthan Steps nearby, this short walk offers equally dramatic scenery with fewer crowds. The headland of Pentire Point provides panoramic views of the coastline, including Rumps Point with its Iron Age cliff castle. In spring and summer, the headland is carpeted with wildflowers, including the rare Cornish heath.

Nare Head and Hemmick Beach (4 miles)

This circular walk on the Roseland Peninsula offers a perfect mix of historical interest and natural beauty. Nare Head was an important lookout point during World War II, and remnants of military installations can still be seen. The path then descends to the secluded Hemmick Beach before climbing back up through farmland with views across Veryan Bay.

Practical Tips for Coastal Walking in Cornwall

Best Time to Walk

While Cornwall's coastal paths can be walked year-round, the best time is generally from late spring to early autumn (May to September) when the weather is more reliable and the days are longer. Spring brings wildflowers, while late summer offers the warmest sea temperatures if you're tempted by a swim. Even in summer, be prepared for changeable weather.

What to Bring

  • Good walking boots with ankle support
  • Waterproof jacket and trousers
  • Layers of clothing (conditions can change rapidly)
  • Sun protection (the coastal exposure can be intense even on cloudy days)
  • Plenty of water and snacks
  • OS map or digital equivalent
  • Mobile phone (though be aware that signal can be patchy on remote sections)

Transportation and Logistics

Many walks can be made circular, but the most dramatic coastal paths are often better walked as linear routes. Cornwall's public transport system, while not extensive, can be useful for coastal walkers. The seasonal Coastal Hopper bus services connect many coastal communities, and there are regular train services along the main rail lines. In many cases, local taxi services can help with drop-offs or pick-ups for reasonable prices.

Safety Considerations

Always check tide times when walking sections with beaches or coves that might be cut off at high tide. Be extremely cautious on cliff edges, especially in windy conditions or when the ground is wet. Inform someone of your planned route and expected return time if walking in more remote areas.

Accommodation Along the Coast

Cornwall offers a wide range of accommodation options for walkers, from luxurious hotels to simple bunkhouses. Many coastal towns and villages have B&Bs and pubs with rooms that cater specifically to Coast Path walkers, offering luggage transfer services, packed lunches, and drying facilities for wet gear. During the peak summer season, it's advisable to book accommodation well in advance, especially in popular locations like St Ives, Padstow, and Fowey.

Final Thoughts

Cornwall's coastal paths offer some of the most spectacular walking experiences in Britain. Every turn of the path reveals new vistas: towering cliffs plunging into churning seas, secluded coves with crystal-clear water, historic harbors bustling with fishing boats, and tranquil estuaries rich with birdlife. Whether you choose a challenging full-day hike or a gentle stroll to a viewpoint, the Cornish coast promises memories that will last a lifetime.

Remember to walk responsibly, respecting the natural environment and local communities, and you'll discover why Cornwall's coastline has inspired artists, writers, and visitors for centuries.
