Cornwall, with its rugged coastline, turquoise waters, and golden sands, is home to some of the United Kingdom's most stunning beaches. While popular spots like Fistral Beach and Porthcurno often steal the spotlight (and the crowds), Cornwall's true coastal magic lies in its hidden coves and secret beaches that remain relatively untouched by mass tourism. Having spent summers exploring Cornwall's 300+ miles of coastline, we're sharing our insider knowledge of the county's most enchanting hidden beaches.
The Charm of Cornwall's Secret Shores
What makes Cornwall's hidden beaches so special is not just their natural beauty, but the sense of discovery they offer. Unlike the county's more accessible beaches with their car parks and facilities, reaching these secluded spots often requires local knowledge, a sense of adventure, and sometimes a challenging cliff path descent. Your reward? Pristine sands, crystal-clear waters, and the possibility of having a slice of Cornish paradise all to yourself.
1. Lantic Bay
Often described as Cornwall's best-kept secret, Lantic Bay near Polruan offers a breathtaking crescent of white sand that seems to glow against the turquoise sea. The steep 20-minute walk from the National Trust car park deters casual visitors, meaning even in high summer you might share this stunning beach with just a handful of people.
Local Tip: Visit on a rising tide when the water warms as it flows over the sun-heated sand. Bring all supplies as there are no facilities.
2. Portheras Cove
Located near Pendeen on the wild north coast, Portheras Cove offers a tranquil escape from the busier beaches. This small sandy cove is sheltered by dramatic granite cliffs and offers excellent swimming in clear waters. Once considered dangerous due to old mine workings, a cleanup operation has now made it safe, though its relative inaccessibility keeps it peaceful.
Local Tip: Park in the small layby on the B3306 and follow the footpath across fields for about 15 minutes. The beach is dog-friendly year-round.
"The best way to experience Cornwall is to seek out its hidden coves. That's where you'll find the Cornwall of your dreams – wild, unspoiled, and genuinely magical." - local Cornish guide
3. Pedn Vounder
Near Treen in West Cornwall lies one of the county's most spectacular beaches. Pedn Vounder sits beneath the cliffs of Treryn Dinas and offers Caribbean-like shallow pools at low tide. Access is via a challenging cliff scramble, which ensures it remains uncrowded despite its increasing Instagram fame. On hot summer days, the white sand and crystal-clear water could convince you you're in the Mediterranean rather than England.
Local Tip: This beach is completely covered at high tide, so check tide times carefully. Also be aware that it's unofficially naturist-friendly.
4. Nanjizal Beach
Located just a mile from Land's End but remarkably quiet, Nanjizal (or Mill Bay) is a photographer's dream with its famous 'Song of the Sea' rock arch and natural stone pools. The fine sand beach appears and disappears with the tides, and the emerald waters are perfect for swimming and snorkeling when conditions are right.
Local Tip: Park in Porthgwarra and walk the coast path for the most scenic approach. Visit in spring to see the beach adorned with wildflowers.
5. Bosahan Cove
On the secluded eastern side of the Lizard Peninsula, Bosahan Cove offers a pristine, sheltered beach backed by ancient woodland. This small sandy cove is accessible only by boat or via a footpath through the private Bosahan Estate (when open) or a longer coastal path walk from Helford village.
Local Tip: Combine with lunch at the Shipwrights Arms in Helford for a perfect day out. The calm, sheltered waters here are ideal for paddling.
6. Lusty Glaze Beach
Although located in busy Newquay, Lusty Glaze feels worlds away from its more famous neighbors. This privately-owned horseshoe-shaped cove is reached via a steep staircase, which helps keep crowds at bay. The beach is sheltered by tall cliffs, making it a sun trap and providing protection from winds. Unlike most secret beaches, Lusty Glaze offers amenities with its excellent beach restaurant.
Local Tip: Visit for one of their sunset sessions – live music as the sun goes down over the Atlantic.
7. Vault Beach (Gorran Haven)
This mile-long stretch of sand near Gorran Haven on the south coast remains quiet even in peak season due to its distance from the car park (a 15-20 minute walk). The eastern end, furthest from the access path, is known locally as 'Sunny Corner' and is popular with naturists. The beach offers excellent swimming and snorkeling in clean, clear waters.
Local Tip: Approach from Lamledra Hill for the most spectacular views as you descend to the beach.
Essential Tips for Exploring Cornwall's Hidden Beaches
- Safety First: Many hidden beaches have no lifeguard coverage. Check tide times and be aware of rip currents, particularly on Atlantic-facing beaches.
- Leave No Trace: These pristine environments stay beautiful because visitors respect them. Take all litter home and leave only footprints.
- Be Prepared: Bring water, food, and sun protection as most secret beaches have no facilities.
- Appropriate Footwear: Many access paths are steep and can be slippery. Wear suitable footwear for cliff walks.
- Respect Local Wildlife: Keep dogs under control and observe any nesting restrictions during bird breeding seasons.
- Check Access: Some beaches are accessible only at low tide. Always check tide times before setting out.
