Grosnez Castle is one of my favourite places in Jersey. I come here often and it never loses its charm. The ruins have such a unique atmosphere, perched high on the cliffs, and on a sunny day the views are unbeatable as you can see Sark clearly!

This is the remains of a castle, of which very little is left. However good views of the other channel islands, military WWII buildings which are not far away and the sun set

Absolutely a spectacular place with all time high wind, but amazing panoramic view of the cliff. It’s quite scary to stand near the edge.

If you're looking for a challenging climb or stunning scenery, this might not be the spot. However, for a relaxing walk in nature, it's perfectly pleasant. 🚶‍♀️

Remember coming here during the summer and it was a marvellous experience. The views are simply astonishing and you can have a great time walking around the paths as it is usually very calm and serene. Would be careful regardless of the weather but especially when it is very windy. If you come to Jersey on holiday I would recommend coming here and spending some time watching the surreal sunrise.
