Start with the correct Marina approach
The council describes the path beginning behind Asda at Brighton Marina. Locate that entrance rather than following the waterfront around every marina basin. Keep the marina visit separate if you want to look at the boats; the Undercliff route is the coast path east beneath the cliffs.
Use the cliff and sea as the route’s focus
Follow the permitted paved path east, noticing the contrast between the bright cliff face and the sea. There is no need to invent a chain of attractions here: the coastal setting is the reason for the walk. Keep away from closed areas, cliff edges and any section affected by debris or breaking waves.
Choose Rottingdean as a manageable decision point
Make Rottingdean your intended stop, then decide whether you still want the return walk. Use the council route information and a current map to find the appropriate exit into the village. If you continue towards Saltdean, treat that as extra walking and plan the return before extending the day.
Arrange the return before you leave
For an out-and-back trip, turn around while everyone is comfortable rather than waiting until the group is tired. For a one-way walk, use Brighton & Hove Buses’ journey planner from your chosen exit back towards Brighton. Check the actual service for your date; do not rely on an unverified route number or assumed last bus.
Replace the outing when the coast is uncomfortable
The path’s low position beside the sea makes wind and wave conditions relevant even when the city centre feels manageable. In rough conditions, choose the Royal Pavilion or a shorter central street walk instead. Wear grippy closed shoes and carry a hooded shell; keep the optional beach stop separate from the main paved route.
Check before you go
Opening arrangements and visitor rules can change. Check the official information before your trip.
