In recent years, tourism has provided a boost to the local economy. Swansea Bay itself was popular in Victorian times and in the early part of the 20th century. However, despite having dunes and golden sands over a large section of the Bay all the way from the mouth of the River Neath to Blackpill, with the exception of the Swansea Docks breakwater, it now rarely hosts more than a few hundred visitors on even the best day, even in the height of summer and has seen little of the tourist boom. Ironically in the last ten years or so, with the reduction in pollution (see below) has come an increase in the amount of sand on the lower stretches of the Bay at low tide which were once almost pure mud flats. The bay in Swansea previously had an abundance of sand but in the last century 300,000 tonnes of sand were removed from the beach and shipped to Blackpool which had a shortage of sand.
