Swansea bay is a great long stretch of beach and in one direction you have the city and the other direction you have Mumbles. Theres lots of cafes and places to visit and you can either walk on the footpath or along the beach. There are always lots of shells and things washed up so great for beach combing or exploring with kids

Bracelet Bay is a small bay on the south of the Gower Peninsula. It is the first bay one comes to after leaving Swansea Bay and rounding Mumbles Head. Surrounded by limestone cliffs, the bay is pebbly, with some sand. To the west, the bay is separated from Limeslade Bay by Tutt Hill, the location of a coastguard look-out station. A notable feature of the bay is the "Big Apple" kiosk, a concrete structure that was erected by the roadside during the 1930s as an advertising feature and has been a sales outlet ever since. Several similar kiosks were erected along the South Wales coast, but the one in Bracelet Bay is the only example surviving. In 2010 it was largely rebuilt after being damaged by a vehicle the previous year, and in 2019 it was designated a Grade II listed building. The name 'Bracelet' is thought to be a corruption of 'Broad Slade'.

NCN43 follows old railways lines, riverbanks and canals from Swansea to Clydach. This section follows an old railway line, it's flat and gravelled, easy riding but pretty and no cars.
