For all the years I have lived near Swansea, I have never walked the full length of the cycle/footpath from Swansea to Mumbles, just different parts of it at different times.
The path runs along the top of the beach from Swansea’s maritime quarter right round to Mumbles Lifeboat Station. On the other side is Oystermouth Road, a busy road along which tourists must drive as well as locals to reach the Gower Peninsula, one of Wales’ most popular areas and was designated as the UK’s first Area of Outstanding Natural Beauty in 1956.
Despite the proximity of Oystermouth Road, the sound clips I recorded recently might suggest that the road is much further away than it is. There was plenty of traffic on it at the time but the light breeze was blowing away from the cycle/footpath and so even for my iPhone, this was not the predominant sound.
