Brighton Hikes Worth the Bus

Brighton doesn’t have hiking trails so much as it has bus stops that happen to open onto the South Downs. The genuine walking here starts where the city ends, and getting there without a car means knowing which bus runs on which day, because the two routes that actually reach the hills don’t run daily. Skip the “Chanctonbury Ring” and “Friston Forest” entries that pad out older Brighton hiking lists (both are a separate car trip, not a Brighton day out) and stick to what’s reachable by bus or on foot. If you’re still picking a base, check rates on Booking.com for somewhere central, since every hike below starts from a bus stop in town.
Four hikes, how you actually get there
| Hike | Access from Brighton | Distance | Difficulty |
|---|---|---|---|
| Ditchling Beacon to Devil’s Dyke | Bus 79 out, bus 77 back (or reverse) | Roughly 4-5 miles, 2-3 hours one-way | Moderate |
| Devil’s Dyke loop | Bus 77 from near the Palace Pier | 2-3 miles for a rim loop | Easy to moderate |
| The Undercliff Walk | Walk or bus to Brighton Marina | 3 miles / 5km, one-way to Saltdean | Easy |
| Seven Sisters cliff path | Bus 12/12A/12X to Birling Gap | Several miles, exposed clifftop | Hard |
The bus-77 trap that catches weekday visitors
If you’re planning a Devil’s Dyke hike for a Tuesday in November, don’t. Bus 77 to Devil’s Dyke runs weekends and bank holidays year-round, plus weekdays only through the summer. Outside that window there’s no direct bus, and it’s the single most common trip-planning mistake in Brighton hiking content, most of which just says “take the 77” without the caveat. Check the current timetable at buses.co.uk before you build a weekday around this hike, not after.
Devil’s Dyke itself is one of the deepest chalk valleys in the UK, about 30 minutes out from the centre through Prestonville and Westdene, opening onto downland with views over the Weald and the Channel and a working hang-gliding launch. The Devil’s Dyke pub sits right at the bus terminus if you want a pint before the walk back. Multiple loop and linear routes radiate from there; if you’ve only got an hour, do the short loop around the dry valley rim for the view and skip the longer walks.
Can you do the Ditchling Beacon to Devil’s Dyke walk without a car?
Yes, and it’s the best linear hike Brighton offers without a train. Bus 79 to Ditchling Beacon runs Sundays and bank holidays year-round, plus Saturdays in the summer, a narrower window than the 77’s. Take it out, walk the South Downs Way west to Devil’s Dyke, and catch the 77 back into town, or do it in reverse.
Ditchling Beacon is 248 metres up, the highest point in East Sussex and third-highest in the South Downs National Park, with the Way’s bridleway running straight through the car park, so there’s no ambiguity about where the trail starts. This stretch is the one South Downs Way section genuinely built around Brighton’s bus network rather than a train timetable, which is why it’s the pick over Chanctonbury Ring or anywhere else that needs a car to reach.
The Undercliff Walk is the hike that doesn’t feel like one
Three flat, paved miles from Brighton Marina to Saltdean, beneath the chalk cliffs, passing Ovingdean Gap and Rottingdean on the way. No elevation, no bus timetable to plan around, and it’s quiet even when the central seafront is packed solid in August. It’s less a hike than a proper walk, but it’s the one entry on this list you can do on a whim without checking a single timetable first. Full detail, including where to start and what’s along the way, is in our Brighton nature spots guide .
Is the Seven Sisters cliff walk worth the bus ride?
Only if you actually want to walk, not just photograph. The Coaster buses (12, 12A, 12X) reach Birling Gap in 75-100 minutes, and from there the cliff-top path toward Eastbourne is multiple miles of exposed clifftop with no shade and no shortcuts back. Most visitors do Birling Gap as a there-and-back photo stop instead, which works fine on the same buses and takes a fraction of the time. Full route and bus-stop detail is in our Brighton day trips guide , since this one’s really a day trip that happens to involve walking, not a Brighton-based hike.
Base yourself where the bus routes actually start
Every one of these routes begins from stops in central Brighton, near the Palace Pier or North Street, so there’s no advantage to staying near the Downs themselves, a central room keeps you within walking distance of every bus stop on this list. If you’d rather not plan bus timetables yourself, browse South Downs walking tours that handle the transport end.
For path conditions and any closures, check southdowns.gov.uk before a longer walk, and confirm bus times at buses.co.uk the morning you travel, not the week before. One concrete move: if you only get one bus-dependent hike into your trip, make it Ditchling Beacon to Devil’s Dyke on a Saturday in summer, when both the 79 and the 77 run and you’re not boxed into a single direction.
