[1] The creek is approximately two miles (3 km) long from its Normal Tidal Limit (NTL) to its mouth and half-a-mile (800 metres) across at its widest point.
Until the beginning of the 20th century, Restronguet Creek (and its tributary rivers) played an important role in the tin and copper mining industry.
At low water, large expanses of intertidal mudflats are exposed (which can be dangerous because the mud is deep and very soft[2][6]) and recent academic study suggests the mud still bears evidence of mineral contamination by former mining activity further upstream.
[7] Today, Restronguet Creek, Carrick Roads and Cornwall's English Channel coast are popular for yachting and dinghy racing.
Restronguet Sailing Club takes its name from the creek although it is located a mile south at Mylor Harbour.
