Great views of this ‘crease’ in the hill. Lots of wildlife on view here, with its natural steep sides, birds of prey are often circling and hoovering. Grazing livestock are also common here.

Really lovely second part to the walk. The climb up is straightforward but quite taxing and steep in places. Difficult if you have knee problems etc

This is a beautiful spot, there is a trig point that is placed on one of the ramparts of the actual Iron Age hillfort here. It is very popular with walkers, and families. The valley bowl is also particularly beautiful.

Good place to start a hike (if in a car) - parking fees going towards upkeep of the area.

Hammer Lane is an impressive narrow sunken road in Chithurst cutting through sandstone and passing over Hammer stream. It’s a lovely section of road cycling, typical of the quiet lanes in this part of West Sussex.

In the South Downs, 'canyons' refer to impressive deep valleys, dry valleys, and dramatic coastal formations carved into the distinctive chalk bedrock.

They offer unique geological insights and stunning landscapes.
Yes, several areas are suitable for families. Devil's Dyke is a popular family-friendly destination, offering expansive views and space for children to explore. The walks along the Seven Sisters Cliffs also provide accessible paths with breathtaking coastal scenery, though care should be taken near cliff edges.

The Seven Sisters Cliffs are an iconic example of the South Downs' dramatic coastal formations. They are the remnants of dry valleys that meet the sea, presenting an undulating landscape of chalk peaks and dips. They offer breathtaking coastal views and are a prime example of the distinctive chalk geology being eroded by the sea, creating a visually stunning 'canyon-like' effect where the land drops sharply to the water.
The geology of the South Downs is primarily characterized by tilted layers of Upper Cretaceous Chalk, formed from marine deposits 75 to 90 million years ago. The distinctive valleys, dry valleys, and coastal cliffs were sculpted by weathering and erosion, particularly during the last ice age. This geological history makes areas like Devil's Dyke and the Seven Sisters significant for their unique formations.
Visitors particularly enjoy the expansive and stunning views, such as those from Devil's Dyke. The tranquil environments of the river valleys, the chance to observe diverse wildlife, and the sense of discovery in places like Standean Bottom are also highly appreciated. Many find the quintessential English countryside experience, with its rolling hills and dramatic formations, to be truly captivating.
