Beautiful views from here of the bay to the south as you follow a well-established path on the shore. Lots of beautiful tall pine trees on the way and some gorgeous viewpoints over the shining waters of the Baltic Sea and the classic small Swedish islands.

A very unusual path over a tiny island runs here, connected by the cutest wooden bridges ever! A total must! - not to mention the fantastic views of the harbour and the sea.

A very nice pier where a few boats are moored. You can walk along the wooden walkways over the water and enjoy a great view.

The place name is probably derived from the Old Icelandic word trauŏur (sluggish, ponderous) and refers to the calm and slow flow of the Trosaån River.
