Peak Hill

For many, the perfect coastal walk is defined by a breathtaking view. But what if a path could offer more? What if it could lead you not just along the edge of the sea, but through the depths of geological time, across a mosaic of vibrant habitats, and among a cast of unique wild inhabitants? Such a place exists, and it stands guard over the western approach to Sidmouth in East Devon.

Peak Hill is far more than a viewpoint; it's a living museum where dramatic landscapes tell a story hundreds of millions of years in the making. Here, the layers of ancient rock are as captivating as the coastal panorama, and the wildflowers and butterflies are as colourful as the autumn heather. This is a place where every step reveals another secret of the Jurassic Coast's profound natural history.

Peak Hill is a prominent landmark rising on the western side of Sidmouth, East Devon. At 159 metres above ordnance datum (AOD), it is one of the highest points on the East Devon coastline, offering commanding views. It holds a significant place within both the East Devon Area of Outstanding Natural Beauty (AONB) and the globally recognised Jurassic Coast World Heritage Site. The beautiful coastal woodlands that grace its slopes are carefully managed by The National Trust, preserving their unique character for all to enjoy.

Look closely at the cliff face of Peak Hill, and you can read a story in stone across three distinct layers, each a chapter from a vastly different ancient world:

1. The base is formed of Triassic Mercia Mudstone, deposited in a hot, dry climate around 200 million years ago.

2. Above this lie the middle layers of Upper Greensand, laid down in a shallow sea about 80 million years ago.

3. The top of the hill is capped with a layer of flint gravel, the last remnants of a chalk cover from 60 to 65 million years ago.

What makes this geological story so profound is the tangible evidence it holds. Within these ancient cliffs, researchers have discovered rare fossils of Triassic fish, reptiles, and amphibians. Each fossil is a tangible link, a stone-cast echo of a world ruled by strange reptiles swimming in waters that covered this very land.

This dramatic geological foundation gives rise to a surprisingly varied tapestry of habitats, each shaped by the underlying soil and its exposure to the coastal elements.

• Coastal Grasslands: The clifftop itself is a carpet of well-trimmed grassland, offering an open vista. It becomes particularly colourful in autumn, not from the grass itself, but from the adjacent heathland of Mutter's Moor which erupts in a blaze of purple heather and yellow gorse.

• Coastal Woodlands: Known as Peak Wood, the "open" woodland features a mix of regenerated scrub and broadleaf trees, interspersed with open grassland areas. A botanical survey of this small wood recorded an impressive 101 different plant species.

Pebblebed Heaths: Peak Hill is directly connected to the adjacent Mutter's Moor, part of one of Europe's largest and oldest pebblebed heaths. This isn't just a local feature; its importance is recognised with designations as a Site of Special Scientific Interest (SSSI), Special Protected Area (SPA), and a Special Area of Conservation (SAC).

This rich mosaic of habitats supports an equally diverse range of flora and fauna. The area is a haven for wildflowers, with over 50 species recorded. The grassland area on Peak Hill, adjacent to Peak Wood, is home to a large colony of yellow-flowered Meadow Vetchling (Lathyrus pratensis), while the delicate white stars of Greater Stitchwort (Stellaria holostea) can be seen flowering in the woods during April.

The animal life is just as fascinating. On a sunny day, watch for the flicker of at least seven species of butterfly as they dance between the wildflowers and along the sheltered woodland edges. In autumn, the air is alive with birds raiding the bushes for their berries. The wider heathland of Mutter's Moor is a stronghold for notable species like the elusive Dartford warbler and, in the quiet of summer evenings, the strange, churring call of the nightjar can be heard.

Peak Hill truly offers a complete natural experience. It combines spectacular coastal views with a profound geological story and a remarkable diversity of plants and animals. It is a testament to the layers of history—natural and geological—that exist right under our feet, often hidden in plain sight.

The next time you stand on a clifftop, what hidden stories of deep time and wild nature will you look for?
