In 1971 a
bridge was built to cross the 700 metre gap between the Ile de
Noirmoutier and the mainland, before that there were only two ways to
reach the island, either by boat or via the Passage du Gois. This uneven stone
paved causeway was first used during the XVI century as the Baie de Bourgneuf
gradually silted up. Today the causeway attracts thousands of visitors a year to
watch the twice daily uncovering of the 4.5 kilometres of road as it
miraculously appears from the sea during the ebbing tide. Visitors come to walk,
cycle or drive across the Gois (from the local patois "goiser" meaning to wade),
the locals also come to fish 'by foot', especially at low spring tides when the
vast expanses of sand which are rich in all manner of shell fish are
exposed. A word of caution, thoroughly check the tide tables, they are marked
on either side of the causeway on large signs because as the area is very
flat the tide rises at an incredible rate and many visitors every year get
caught out. There are a few " balises", large sturdy wooden towers, which one
can climb and wait until you are rescued or the tide falls
again.
During the Wars of
the Vendée, both the Republican and Vendéen armies used the causeway to
surprise the opposition and the Ile de Noirmoutier changed hands several
times.
