Porthbeor Beach, near St Anthony Head, Roseland Peninsula, Cornwall, TR2

Porthbeor Beach is one of the most genuinely secluded and unspoilt stretches of sand anywhere on the Roseland Peninsula, a small, undeveloped cove tucked beneath low cliffs on the more remote southern shore near St Anthony Head. Unlike St Mawes a little further round the coast, Porthbeor has no road leading to it and no car park at the beach itself - there is no way to drive directly to this beach at all. It is reached only on foot, via a walk down from the South West Coast Path, which makes it one of the quietest and least-visited beaches on this part of the coast, and a genuine reward for anyone prepared to make the walk rather than simply pull up beside the sand. For visitors used to the more accessible, better-served beaches of the Roseland's villages, Porthbeor offers a different kind of experience altogether: a proper walk-in cove, close to nature, with nothing waiting at the bottom but the beach itself.

The nearest parking is the National Trust car park at Porth Farm, close to St Anthony Head, from where a coast path walk of around a mile leads down to the beach - a walk that varies in length and difficulty depending on the exact route taken and is best approached with sturdy footwear rather than beach sandals. There is no direct path from any nearby road, and no signage or facilities to speak of once away from the car park, so visitors should come properly prepared, particularly outside the main summer months when the path can be muddy underfoot. The reward for the walk is a genuinely quiet cove that rarely sees anything like the crowds of St Mawes or the peninsula's more accessible beaches, even at the height of summer.

Porthbeor is backed by low cliffs, and the usable width of sand changes considerably with the state of the tide - at high water the beach narrows substantially and can, in the wrong conditions, be effectively cut off from easy return along the shore, so visitors should always check tide times before setting out and allow enough time to walk back up to the coast path before the water closes in. This tidal narrowing is a common feature of many of the Roseland's smaller, cliff-backed coves, and Porthbeor is no exception - a falling or low tide gives by far the most beach to enjoy, and the safest, most comfortable visit.

There are no facilities of any kind at Porthbeor - no shop, no cafe, no toilets and no lifeguard cover, in keeping with its status as one of the Roseland's genuinely undeveloped, walk-in beaches. Visitors need to bring everything they might need for the day, including water, sun protection and anything for small children, since there is nothing to buy once away from Porth Farm or the villages further round the coast. This lack of infrastructure is precisely what has kept Porthbeor as unspoilt as it is, and it suits confident, well-prepared walkers and swimmers rather than a straightforward family beach day with all the usual seaside trimmings close at hand.

Porthbeor's setting close to St Anthony Head gives it a real bonus for anyone making the walk down: the headland itself is one of the most rewarding short walks on the whole Roseland Peninsula, owned and managed by the National Trust, with sweeping views out across the mouth of the Carrick Roads to Pendennis Point and Falmouth on the opposite shore. St Anthony Head carries the remains of a Second World War coastal battery, built to guard the approach to Falmouth and the Fal estuary during the war, and walkers can still pick out gun emplacements and other military structures among the gorse and grass on the headland today. At the very tip of the headland stands St Anthony Head Lighthouse, built in 1835 to warn shipping away from the rocks at the entrance to the Carrick Roads and automated in 1987, ending the era of resident lighthouse keepers here as it did at so many other Cornish lighthouses. The lighthouse and its surrounding National Trust land are a popular short walk in their own right, easily combined with a visit to Porthbeor Beach on the same outing - many visitors approach the beach as one leg of a longer circular walk taking in the headland, the lighthouse and the wider coast path around this part of the Roseland.

Geologically, the low cliffs backing Porthbeor are formed from the slate and shale, known locally as killas, that underlies much of the Roseland Peninsula, weathering into the smaller, more broken ledges and outcrops typical of this coast rather than the towering granite cliffs found elsewhere in Cornwall, such as around Land's End or the Bodmin Moor fringe. St Anthony Head itself carries a much older layer of history beneath its wartime remains: the wider headland was of strategic value long before the Second World War, guarding as it does the entrance to one of the finest natural deep-water harbours in Britain, and the battery built here in 1940 was one of a number of coastal defences hurriedly constructed around the Carrick Roads and Falmouth to protect the anchorage and dockyard during the war, before being decommissioned once the threat had passed.

The low cliffs and open coastal grassland around Porthbeor and St Anthony Head are good territory for spotting seabirds throughout the year, with seals occasionally seen offshore in the calmer water below the headland, and the gorse and heather that cover much of this stretch of coast put on a good display of colour through late summer. The coast path along this section of the Roseland gives some of the most consistently open sea views on the whole peninsula, largely free of development in either direction, which is part of what makes the walk down to Porthbeor as much a part of the visit as the beach itself. This is a stretch of coast that rewards unhurried exploration rather than a quick stop, and the walk to and from the beach is worth allowing proper time for.

Porthbeor sits within a short, varied stretch of coast path between St Mawes and Great and Little Molunan, two further sandy coves reached in much the same walk-in fashion a little further towards St Anthony Head. Together these beaches make up one of the most rewarding short sections of the South West Coast Path anywhere on the Roseland - a genuine contrast to the sheltered, developed harbour beach at St Mawes just a few miles back along the shore. For anyone staying in St Mawes or elsewhere on the peninsula and looking for a proper walking day rather than a straightforward drive-up beach visit, a circular route taking in St Anthony Head, its lighthouse, Porthbeor and the Molunan coves makes for one of the best mornings or afternoons the Roseland has to offer.

The best time to visit Porthbeor is on a calm day with a low or falling tide, giving the most sand to enjoy and the most comfortable walk back to the coast path afterwards. Because there is no dedicated accommodation hub at Porthbeor itself, most visitors base themselves either at nearby St Mawes, a short walk and ferry ride away, or within the parish of St Anthony in Roseland, which covers this stretch of the peninsula including the beach itself. Either base puts Porthbeor, St Anthony Head and the neighbouring Molunan coves within comfortable reach for a day of quiet coastal walking.
