The
River Fal flows through
Cornwall,
England, rising at Pentevale on
Goss Moor (between
St. Columb and
Roche) and reaching the
English Channel at
Falmouth. On or near the banks of the Fal are the castles of
Pendennis and
St Mawes as well as
Trelissick Garden. The River Fal separates the
Roseland peninsula from the rest of Cornwall. Like most of its kind on the south coast of Cornwall and Devon, the Fal estuary is a classic
ria, or drowned river valley. The Fal estuary from Tregony to the Truro River was originally called
Hafaraell (, meaning
fallow place).
