If you’re planning a family fun day out at the beach, which one should you choose and which one should you avoid? We have picked a few of the best beaches in Sussex in this gallery below.
1. South Lancing
This shingle beach between Shoreham-by-Sea and Worthing is popular with dog walkers, sailing enthusiasts, windsurfers and kite-surfers. Photo: Steve Robards
2. Bosham Quay
This pretty beach and village is on one of the inlets of Chichester harbour. It is a great place to visit for free, but visitors are warned that the tide can come in rather fast. Photo: Steve Robards
3. Brighton Beach
This one is always a big hit on hot days as it has the Palace Pier, a great town for shopping and lots of places to eat. However, it does have a reputation for getting crowded so maybe it's not the best place for people who want peace and quiet. Photo: Jon Rigby
4. Hastings and St Leonards
People made the most of these fabulous beaches last summer with revellers seen sunbathing, kayaking and swimming in the sea. Photo: staff
