Lowestoft, the easternmost town in the United Kingdom, lies on the North Sea coast 110 miles north-east of London, 38 miles north-east of Ipswich and 22 miles south-east of Norwich. It is divided by Lake Lothing, which forms the inner part of Lowestoft Harbour and provides access via Oulton Broad and Oulton Dyke to the River Waveney and the Broads. Lowestoft is mainly low-lying, but with hilly areas in the north of the town and high points of 20–30 metres above sea level.
