Swansea Bay (25 minute drive from Parc-Le-Breos B&B) stretches over 5 miles, all the way from the marina entrance in Swansea to the Victorian pier of Mumbles. It is generally a sandy shallow shelving bay and, though not as spectacular as some of the Gower beaches, it is as pretty a back drop as any city could be blessed with. There is a promenade and cycle track stretching the entire length which is often busy with cyclists, joggers and walkers. There are numerous shops and cafés where you can stop and watch the world pass you by. The cafés are concentrated at the Mumbles end, and about halfway at Blackpill. Near to the Lido and play areas there are also various (free to use) exercise machines along the way. One particular point of interest can be found at the low tide mark near to Mumbles - the remains of a petrified forest from times of lower sea levels.
The bay is popular for water sports, with boat launching at Knab rock (Mumbles) where the headlands provide sheltered water for water skiing and wakeboarding. There is a slalom course and ramp out to the east of the moorings. The middle of the bay near to Singleton seems to have become popular with windsurfers, kite surfers and buggies - probably due to the plentiful space.
Many dive boats also launch from here when the visibility is good and head out to the Strombus wreck (just outside the moorings) and Gower coast beyond.
The bay is popular with fishermen, with the two most favoured points probably being the pier at Mumbles and the piers of Swansea Marina at the other end of the bay. At low tide the mud at the low shore from Blackpill to Mumbles is a good place to dig for lugworm and ragworm.
Not regarded as a good surfing beach, much of the beach is too sheltered, and when it does get surf, it's generally sloppy and shapeless. That’s not to say there is never a rideable wave here, but when you're spoiled by the Gower Peninsular next door there’s usually a better choice to be made.
