  • Sometimes signposted as Bae Cas-wellt in Welsh, Caswell Bay is a Blue Flag beach located on the south-eastern side of the Gower Peninsula close to The Mumbles. Offering a wide expanse of dark golden coloured sand, which reduces significantly in size at high tide, it is occasionally interrupted by natural rock formations. Behind the beach is the free-to-visit Bishop’s Wood Nature Reserve.

    Caswell Bay is popular with families with buckets and spades looking for a traditional beachside holiday. As well as sand castle building and wave jumping, low tide reveals a number of rock pools filled with an array of marine creatures. Other reasons to visit Caswell Bay include its reputation as a surf spot. Beginners can take advantage of the on-site surf school, which provides lessons year-round.

    Accessible by both car, and bus from Swansea, Caswell Bay also has a year-round cafĂ© and a beach shop, in addition to public toilets and outdoor showers. There is a lifeguard presence between the start of May and start of September of each year, during which time dogs are banned from using the beach. Caswell Bay is accessible for those with disabilities. To guarantee a parking space during the summer holidays and sunny days it’s worth arriving before 10 am.

    Fantastic family beach

    Dec 16th 2020

    Perfect family beach.  Lots of space, beautiful sand, lovely view out to sea, sheltered spots around the edge of the beach to make a “base”, some rock pools, a small chine that provides water for moats around sandcastles, lots of space, cafe is decent but not too pricey / pretentious, couple of shops for beach items you’ve forgotten.
    Only two important things to note:
    - get there reasonably early on busy days - the one car park is reasonable size but once it’s full there’s nowhere else.  We always try to get there by 1000, we’ve always found that OK but wouldn’t leave it much later.
    - at the height of high tide there’s hardly any of it - see the OS map high water line - so worth checking before you go.

    I love this little beach, my only problem with it is parking gets very difficult in hot weather.
