The castle is gigantic and beautiful to look at, unfortunately it has been surrounded by a construction fence for ages. Unfortunately, you can't see much. Whether the detour is worth it, everyone has to decide for themselves.

Definitely a highlight, but unfortunately, the castle was covered in scaffolding when I visited. The castle dates back to the Middle Ages but was later almost completely rebuilt.

A wonderful breath of fresh air. You can also do this part barefoot.

First part unpaved, if it has rained in the days before it will be muddy and slippery

I've been going there for many years. It's not really a beach, but a cove of fine pebbles, and swimming requires caution; there are a lot of rocks at the entrance. The surrounding area allows for several trails.

Ours is a traditional Plentzia bar, located opposite the passageway. On sunny days, it's a real pleasure to have an aperitif on the terrace overlooking the estuary.
