Land’s End is the beginning or end of one of Britain’s greatest challenges: the walk from Land’s End to John o’ Groats. “From Land’s End to John o’ Groats” has now become a household phrase on the island and is always used when talking about long distances.

Lovely walk, lots of interesting and varied scenery. We did it on a good November day and some short sections inland were very muddy

The RMS Mülheim was a German Cargo ship that was wrecked here in between Sennen Cove and Lands End. At first the whole ship, which was carrying scrap plastic from cars, was stranded on the rocks but over time the hull broke in two and it was washed up into the cove known as Castle Zawn.

The River Fowey tumbles its way down the Golitha Falls, a collection of waterfalls in Draynes Wood. It is also a haven for wildlife with salmon, sea trout, otters and bats all present. No trip to Bodmin Moor would be complete without a visit here. It is especially spectacular after heavy rain.

Nice wreck… it’s dangerous so don’t be tempted to go exploring as the air ambulance crew will be cursing you when you injure yourself

Cornwall AONB is characterized by dramatic coastal formations, deep river valleys, and rugged gorges. You'll encounter diverse landscapes from granite uplands to sea cliffs. Notable features include impressive sea stacks like those at Bedruthan Steps, gorge-like river valleys such as the Tamar Valley, and unique geological formations like the exposed oceanic crust on The Lizard Peninsula. You can also find spectacular waterfalls, ancient woodlands, and secluded coves.
Yes, the region is rich in history. The Tamar Valley, for instance, holds World Heritage status due to its exceptional mining heritage landscape. Along the Pentire Point to Widemouth section, you can find medieval remains like Tintagel Castle and Iron Age hillforts. The St Agnes Coast features the iconic Wheal Coates engine house, a Cornish Mining World Heritage Site dramatically perched on the cliffs.
The region boasts several stunning coastal formations. The iconic sea stacks of Bedruthan Steps are particularly impressive, especially at low tide. Other notable areas include the high cliff lines from Pentire Point to Widemouth, featuring locations like Boscastle and Tintagel. The westernmost region, West Penwith, offers dramatic cliffs such as Carn Les Boel and Carn Barra, leading to Land's End. For a unique experience, visit The Devil's Frying Pan, a natural monument formed by a collapsed sea cave with an impressive stone arch.
Many areas offer accessible paths suitable for families, though some coastal trails can be challenging. For example, Lydford Gorge (just outside Cornwall AONB but a popular nearby attraction) offers a stunning walk through ancient woodland with dramatic river features and impressive waterfalls, managed by the National Trust. When planning, look for trails described as 'easy' or 'moderate' and check specific route details for suitability with children or strollers.
The spring and summer months (April to September) generally offer the best weather for exploring, with longer daylight hours and milder temperatures, ideal for hiking and enjoying the coastal scenery. However, the dramatic landscapes can be equally stunning in autumn and winter, offering a wilder, more rugged experience, though some paths may be muddy or slippery. Always check local weather conditions before heading out, especially along exposed coastal paths.
Beyond exploring the gorges and coastal paths, Cornwall AONB offers a wide range of outdoor activities. You can find numerous road cycling routes, such as those detailed in the Road Cycling Routes in Cornwall AONB guide. There are also excellent options for gravel biking, with routes like the Iron Bridge on the Camel Trail, as highlighted in the Gravel biking in Cornwall AONB guide. For those who enjoy hiking, the Waterfall hikes in Cornwall AONB guide features trails like the Tintagel Castle loop.
Many trails along the coast and through the valleys are dog-friendly, offering fantastic opportunities for walks with your canine companion. However, it's always best to keep dogs on a lead, especially near cliff edges, livestock, or in areas with ground-nesting birds. Some beaches may have seasonal restrictions for dogs, so check local signage. For specific routes, look for guides that mention dog-friendly walks.
The Lizard Peninsula is considered one of Cornwall's most geologically interesting areas, featuring an exposed section of the Earth's oceanic crust, regarded as the best example of its kind in the country. Here you can explore unique serpentine rock formations, particularly at Kynance Cove. Other areas like the Godrevy to Portreath stretch also feature high cliffs and secluded coves, showcasing the region's dramatic geological history.
While many areas are popular, you can find quieter spots. The Coastal Cliffs from Land's End to Mill Bay offer expansive views and are often less frequented than other parts of the coastline. Another intriguing spot is Ralph's Cupboard, a sea cave formed by erosion, steeped in local legend. The Hartland Coast, extending to the Devon border, also contains hidden valleys such as Coombe Valley, offering rugged beauty and tranquil natural settings.
Parking is available at many popular viewpoints and trailheads, often in National Trust or local authority car parks, which may require a fee. Public transport options, such as local bus services, can also provide access to various coastal towns and villages, allowing for linear walks along the South West Coast Path. It's advisable to check specific access points and parking availability for your chosen destination in advance, especially during peak season.
Yes, safety is paramount. The coastal paths can be challenging, with significant elevation changes and narrow sections. Always wear sturdy, appropriate footwear. Be mindful of cliff edges, which can be unstable, and keep a safe distance. Weather conditions can change rapidly, so be prepared for rain and wind. If exploring sea caves or beaches, be aware of tide times to avoid being cut off. Some areas, like Willapark Lookout and Rocky Valley, are noted for challenging trails where sure-footedness is essential.
Yes, Cornwall AONB is well-equipped with amenities. Many coastal towns and villages, such as Boscastle, Tintagel, and those on The Lizard Peninsula, offer a variety of cafes, pubs, and accommodation options ranging from B&Bs to hotels and self-catering cottages.
