Great Ganilly
Great Ganilly is the largest of the Eastern Isles, a scattered archipelago of small islands and rocky outcrops lying to the east of St Mary's in the Isles of Scilly, off the far southwestern tip of Cornwall. It is an uninhabited tidal island of outstanding natural and archaeological significance, beloved by visitors who reach it by boat from St Mary's or St Martin's. Though modest in size, Great Ganilly punches well above its weight in terms of natural beauty, birdlife, and prehistoric heritage, making it one of the most rewarding destinations for explorers willing to venture beyond the main inhabited islands of the archipelago.
The island's archaeological credentials are exceptional. Great Ganilly is home to a remarkable concentration of Bronze Age entrance graves, the distinctive chambered tomb type characteristic of the Isles of Scilly. These low, round cairns with their stone-lined entrance passages date back roughly three to four thousand years and represent some of the best-preserved prehistoric funerary monuments in Britain. The Isles of Scilly as a whole contain more entrance graves per square mile than almost anywhere else on Earth, and Great Ganilly holds a notable share of this remarkable legacy. Archaeologists believe that the islands may once have been a single larger landmass, and rising sea levels since the Bronze Age have gradually fragmented what was perhaps a more densely inhabited territory into the scattered islets seen today, a process that lends the entire Eastern Isles group an air of ancient, drowned landscape.
In physical character, Great Ganilly is a place of wild, wind-scoured beauty. The island is low-lying but rises at its central spine to a modest rocky ridge, and its shoreline alternates between pale sandy beaches, smooth wave-worn boulders, and jagged granite outcrops draped in orange and grey lichen. The heathland interior is covered in heather, bracken, and coarse grass, with thrift and sea campion colonising the cliff edges. Sounds on the island are almost entirely natural: the cry of herring gulls and oystercatchers, the rhythmic wash of Atlantic swell against stone, and the constant, soft breath of the sea wind. On calm summer days the shallow waters surrounding the island are a vivid turquoise and emerald, their clarity remarkable even by British standards.
The Eastern Isles form a tight constellation of islets and rocks around Great Ganilly, including Great Arthur, Little Ganilly, Nornour, and a host of smaller skerries. Nornour is perhaps the most archaeologically intriguing of the group, having yielded a hoard of Roman figurines and brooches — objects interpreted as votive offerings at what may have been a shrine — suggesting the islands were visited and venerated well into the Roman period. The waters between these islands are rich in marine life, and grey seals are a near-constant presence, hauling out on the lower rocks or surfacing with curious, whiskered faces alongside visiting boats. The birdlife in the Eastern Isles is outstanding, particularly during autumn migration when rare warblers and other vagrant species shelter in the sparse vegetation.
Access to Great Ganilly is by boat trip from St Mary's Hugh Town quay or from St Martin's. Several local boatmen run regular wildlife and island-hopping services throughout the season, typically from April through October, and the Eastern Isles are a standard destination on the circuit. Visitors are landed by small tender onto the beach and are free to explore on foot; there are no facilities whatsoever on the island, so everything needed must be brought along. Sturdy footwear is advisable as the terrain is rough and rocky, and the weather in the Isles of Scilly, while famously mild, can change quickly. The best time to visit is late spring through early autumn; May and June offer wonderful wildflowers and nesting seabirds, while September and October are prime for migrant birds.
Great Ganilly carries a certain profound quietness that is hard to find in modern Britain. Standing among the heather-covered Bronze Age cairns with the Atlantic stretching away in every direction, the feeling of historical depth and geographic isolation is acute. The island has no permanent habitation and likely hasn't supported permanent residents for many centuries, yet the evidence of ancient human presence — in the carefully constructed stones of the entrance graves — gives it a sense of layered time quite unlike a merely empty or remote place. For many visitors to the Isles of Scilly, a boat trip to the Eastern Isles with a landing on Great Ganilly is among the most memorable experiences the archipelago has to offer, combining natural splendour with the quiet contemplation of deep prehistory.
