Bognor Regis
Bognor Regis is one of Arun’s largest and best-known towns. Its identity is closely tied to the sea: the promenade, beach and pier form the obvious visitor focus, while the town centre sits immediately behind the seafront. It has the familiar ingredients of an English resort but is also a working town used year-round by local residents.
A visit can be as straightforward as walking the promenade and spending time on the beach. The shoreline extends beyond the central resort area toward neighbouring coastal communities, so it is easy to turn a short seafront stop into a longer walk. Conditions on a shingle beach can differ significantly between high and low tide, and sea conditions should always be treated with respect.
Littlehampton
Littlehampton occupies a particularly interesting position at the mouth of the River Arun. The river, harbour and sea meet here, giving the town a maritime character that is distinct from Bognor Regis. The seafront provides traditional beach recreation, while the river offers another axis for walking and watching boats.
The town is useful for families and casual day trips because several attractions and open spaces sit close to the coast. Visitors should note that tidal water around a harbour entrance can be powerful; official local guidance specifically warns against swimming in the first bay next to Littlehampton Pier because of strong tides. Use designated swimming areas and observe flags and lifeguard advice.
Arundel
Arundel is the historic counterpoint to Arun’s seaside towns. Its castle dominates the townscape, while the cathedral and sloping streets create one of West Sussex’s most recognisable skylines. The centre is compact enough to explore on foot, with historic buildings, shops, cafés and riverside surroundings all close together.
The River Arun passes the town before continuing south toward Littlehampton. That geographic connection is a useful way to understand the district: inland history and countryside are linked directly to the coast by the same river from which Arun takes its name.
Beyond the three main centres
Arun includes many other communities, including Felpham, Middleton-on-Sea, Yapton, Barnham and villages toward the South Downs. These places are less likely to dominate a first-time itinerary, but they are an important part of the district’s character. Coastal villages provide alternatives to the busier resort centres, while inland settlements reveal the agricultural and rural landscape behind the coast.
