Hidden Gems Near Falmouth

Updated 5 August 2026
The hidden gems near Falmouth are Lamorran House Garden, Loe Beach, Kennall Vale, Carnon Viaduct, Stithians Reservoir, Tremayne Quay, Newham Trail and Carn Marth Little Quarry.
Falmouth is ringed by creeks, wooded valleys and quiet corners of Cornwall, and the good news is that most of these hidden gems sit within a dozen kilometres of the town. Just across the water on the Roseland lies the subtropical Lamorran House Garden above St Mawes, while the sheltered shingle of Loe Beach at Feock is a fine base for kayaks and paddleboards.
Inland you can wander the mossy gunpowder ruins of Kennall Vale at Ponsanooth, stand beneath the arches of Carnon Viaduct near Perranwell, or take to the water at Stithians Reservoir out toward Redruth. Down on the Helford, the old stone Tremayne Quay waits at the end of a woodland walk.
Closer to Truro, the level Newham Trail traces a former railway along the river, and up on Carn Marth a flooded quarry pool sits near the summit. Here are eight hidden gems to seek out near Falmouth.
Lamorran House Garden

Wander Lamorran House Garden A private subtropical garden built into a steep, south-facing hillside above St Mawes, on the Roseland peninsula, and only a short hop across the water from Falmouth. About four acres of terraces and stairways run through dense planting of palms, tree ferns and Mediterranean and southern-hemisphere species, with Japanese-style water gardens, koi ponds and a temple folly, and views over the harbour to St Anthony Head.
Robert and Maria-Antonietta Dudley-Cooke created it from 1982. It opens on set days through the season for an entry fee.
Loe Beach

Launch a kayak at Loe Beach A small, mainly shingle beach on the sheltered western shore of the Carrick Roads, the wide estuary of the Fal, below the village of Feock a few miles south of Truro. The calm estuary water makes it a good base for watersports, with a sailing and paddle centre on the shore hiring kayaks and paddleboards and running lessons, plus a cafe, toilets and a car park.
Rock pools appear at the beach edges at low tide. Note that this is a different place from Loe Bar and Loe Pool near Helston.
An easy trip close to Falmouth.
Kennall Vale

Kennall Vale hides the mossy ruins of a nineteenth-century gunpowder works among its trees, the old mills once driven by water led off the Kennall River along a web of leats. This wooded nature reserve fills a steep river valley at Ponsanooth near Falmouth in Cornwall, looked after by the county wildlife trust.
Broken buildings and a flooded quarry lie scattered through the damp, deep-green wood, and paths wind between them. The place is busy with birds and bats, and the river slips past with dippers working its banks.
It is part woodland walk, part industrial relic.
Carnon Viaduct

Stand beneath Carnon Viaduct This viaduct carries the single-track railway between Truro and Falmouth across the Carnon valley in Cornwall, near Perranwell. The present nine-arch stone viaduct dates from 1933, and beside it stand the tall masonry piers of Brunel's original timber viaduct of 1863, left in place after the wooden deck was removed and known locally as Brunel's stumps.
The line above is still in use, but the valley floor beneath is open: the Coast to Coast mineral-tramways trail passes right under it, giving close views of both the arches and the old piers.
Stithians Reservoir

Get on the water at Stithians Reservoir A large inland lake near Redruth, the biggest stretch of fresh water in the west of Cornwall, made by damming a valley in the 1960s. It is a busy watersports spot, with sailing, windsurfing, kayaking and paddleboarding run from a lake centre on the shore, along with fly-fishing for trout.
A walking trail of about five miles loops the water, and the quieter arms of the reservoir are a well-known place for birdwatching, with hides looking out over the water. There is a cafe, a campsite and a play area by the lake.
Tremayne Quay

Tremayne Quay Built in the 1840s to receive Queen Victoria, this solid stone landing never saw its royal guest, who decided against sailing up the river after all. It stands on a wooded, tidal reach of the Helford in Cornwall, part of the Trelowarren estate, its walls made of dry stone rubble with dressed granite for the steps and copings.
You reach it on foot through National Trust woodland along the old carriage drive, and it draws walkers along with people arriving by kayak or small boat. The Trust has looked after the quay and its surrounding woods since 1978, keeping the spot quiet and green.
Newham Trail

Cycle the Newham Trail An off-road walking and cycling path along the east bank of the Truro River, following the course of a former railway branch between the Newham area south of the city and central Truro. The flat, made-up path runs along the river and estuary with wide water views and wildlife, on the line that was once Truro's first passenger terminus before the main station opened, after which it carried only goods to Newham quay.
Cornwall Council has resurfaced and improved it as one of a set of local Truro walking and cycling routes.
Carn Marth Little Quarry

Find the pool at Carn Marth Little Quarry One of the water-filled workings near the top of Carn Marth, a flooded former granite pit rather than the open-air theatre pit nearby. The pool sits ringed by rock and rough ground, and people use it informally for fishing and swimming.
Several old quarries pock this part of the hill, some now open water and others grown over. This is the flooded one, close to the summit of Carn Marth.
