Brighton's Scenic Coastal Path: Your guide to the Undercliff Walk
The Undercliff Walk is a 3-mile coastal path between Brighton Marina and Saltdean, offering sea views and easy, traffic-free walking.
Whether you're chasing sea spray on a blustery morning or basking in golden-hour light as the tide creeps in, the Undercliff Walk is one of the south coast’s most quietly breathtaking experiences.
Hugging the shoreline between Brighton Marina and Saltdean, this traffic-free path winds beneath towering chalk cliffs and opens out to endless sea views. It’s a route cherished by locals and visitors alike.
In this guide, you’ll find everything you need to plan your own walk – from route tips and seasonal highlights to the local secrets that make Rottingdean the perfect place to start (or end) your adventure.
What is the Undercliff Walk?
Built between 1930 and 1933, the Undercliff Walk was originally a bold feat of coastal engineering – a seawall designed to protect the soft chalk cliffs from erosion.
But what began as a defence has become one of the most scenic strolls in Sussex, offering a front-row seat to the ever-changing moods of the English Channel.
Today, the path stretches just under three miles between Brighton Marina and Saltdean, running flanked by sheer white cliffs on one side and the open sea on the other. It’s fully paved and mostly flat, making it ideal for walkers, runners, cyclists, pushchairs, mobility scooters and dogs on leads.
Where does the Undercliff Walk start and end?
The Undercliff Walk stretches for just under three miles along the Sussex coast, running from Brighton Marina in the west to Saltdean in the east. It’s a linear route, so you can start from either end – or, better yet, begin at Rottingdean, which sits right in the middle.
Many walkers choose to start at Brighton Marina and head east, but for a gentler, more scenic experience, we recommend beginning in Rottingdean – especially if you’re staying at The White Horses.
From our doorstep, you can join the path within moments and enjoy the most picturesque stretch of the walk, with far-reaching views and fewer crowds.
The route is flat, fully paved and traffic-free, making it ideal for all abilities. It’s popular with wheelchair users, cyclists, dog walkers and families with buggies. Officially, cycling is permitted, though you’re asked to give way to pedestrians and ride considerately.
Heading east from Rottingdean, the path skirts the base of the dramatic Saltdean cliffs, where the landscape opens out to uninterrupted sea views and the sound of waves echoing off the chalk.
Allow around 45 minutes to an hour each way, depending on your pace and photo stops (of which there will be many).
What to expect along the way
Step onto the Undercliff Walk and you’re stepping into another world.
On one side, the Brighton cliffs rise in chalky splendour, their white faces streaked with history and softened by pockets of wildflowers in spring. On the other, the sea stretches out endlessly – calm and glassy on summer mornings, wild and thrilling when winter winds whip through.
At low tide, rockpools appear below the seawall, dotted with seaweed, barnacles and tiny marine life. It’s a quiet haven for beachcombers and kids with nets. Gulls wheel overhead, and if you’re lucky, you might spot a cormorant drying its wings or hear the sharp cry of an oystercatcher.
Benches are spaced along the path, offering ideal spots to catch your breath, snap a photo or simply watch the waves roll in. It’s a place for jogging, meandering, reflecting – always with the soundtrack of the sea at your side.
Just watch your footing after storms or unusually high tides. The path can become slick or partially submerged. Always be sure to check the forecast before heading out.
Best time to walk the path
The Undercliff Walk is open year-round, but some moments bring a special kind of magic. Early mornings are peaceful and golden. It’s the perfect time to greet the day as sunlight spills across the sea. In the evening, the cliffs glow warm with sunset light, and the crowds thin to a trickle.
Spring and early summer are ideal for wildflowers and gentler temperatures, while autumn offers crisp air and fewer people. In mid-summer, aim for early or late walks to avoid the heat and glare – the path is unsheltered, and the sun can be fierce.
Winter walkers should be wary of high tides and stormy spells. Parts of the route may close temporarily for safety after heavy rain or coastal erosion.
Before setting out, check Brighton tide times and local weather. The sea has its own agenda here, and it pays to be prepared.
Local favourite: The White Horses as your basecamp
Of all the hotels near the Undercliff Walk, none are quite as perfectly placed as The White Horses. Tucked right above the shoreline in the heart of Rottingdean, we’re part of the fabric of the coast. And for walkers, it’s the perfect basecamp.
You can be on the Undercliff Walk within moments of finishing your morning coffee, or wander back from Brighton Marina in time for sundown cocktails at the Discovery Bar.
Stay the night and wake to the sound of waves outside your window. Sea-view rooms put you front and centre for sunrises and storm-watching alike. Our dog-friendly spaces mean you can bring your four-legged walking companion too. Tails often wag their way straight from the cliffs to our bar.
Drop in for a pre-walk breakfast, warm up with a seaside lunch, or toast your trek with a locally crafted negroni. Whether you’re staying over or stopping by, we’ll have your table ready, and a view to remember.
Practical tips for your walk
Here’s what you need to know before setting off on the Undercliff Walk:
- Parking: You’ll find public car parks at both Rottingdean seafront and Brighton Marina. Free street parking is limited, so arrive early if you can.
- Transport: The #12 bus runs regularly between Brighton and Rottingdean, stopping just steps from The White Horses.
- Toilets: Facilities are available at Brighton Marina and along Rottingdean’s lower promenade.
- Dogs: Welcome on leads. Just keep an eye out for cyclists and mind nesting birds in spring.
- Footwear: Trainers or walking shoes with grip are best. The path is exposed, so bring a windproof jacket or extra layers just in case.
- Food & drink: Bring water and snacks, or stop for a bite to eat at The White Horses or one of the marina’s cafés to refuel.
There’s little to no shelter along the route. Make sure you dress for the elements, and don’t forget your camera.
