Visit the island's west coast and admire the giant willow puffin sculptures, commissioned by Bird on the Edge and the National Trust for Jersey. The sculptures were displayed to mark the arrival of the puffins, acknowledging the plight of these wonderful birds and Jersey's vital role in protecting puffins and other seabirds.

Grosnez Castle is a small 14th-century castle ruin located 4.5 kilometers from Saint Ouen, on the northwest coast of the Channel Island of Jersey. The name is derived from the Patois word grar ness – for "grey headland" – an apt description of the site. The castle was built around 1330 by Sir John des Roches. The gatehouse, the highest remaining part of the ruins, was protected by a drawbridge and a portcullis. However, the castle had several weaknesses. There was no second level of defence and no sally ports for counterattacks. Most importantly, there was no water supply within the walls. The castle was captured by French troops in 1373 and 1381 and was probably destroyed during the occupation of Jersey (1461–1468). Source: https://de.m.wikipedia.org/wiki/Grosnez_Castle

With its sun-drenched headland and soft sandy beaches, Jersey's west coast offers some of the island's most enchanting spots. A long stretch of golden sand and views of the Atlantic make St. Ouen's Bay truly special. Source: https://www.jersey.com/things-to-do/points-of-interest/listings/st-ouens-bay/
