Further out the fjord is fairly remote but rich with natural interests including puffin colonies and ruins of former activity such as nearby Vestdalseyri [ˈvɛstˌtalsˌeiːrɪ], from where the local church was transported.

Another now-deserted settlement nearby in the fjord, Vestdalseyri was the site for the world's first modern industrialized whaling station.

The first telegraph cable connecting Iceland to Europe made landfall in Seyðisfjörður in 1906, making it a hub for international telecommunications well past the middle of last century.

Seyðisfjörður was used as a base for British/American forces during World War II and remnants of this activity are visible throughout the fjord, including a landing strip no longer in use and an oil tanker SS El Grillo that was bombed and sunk.

It still remains a significant fishing port on the east coast of Iceland, with harbours, ship construction facilities and a slip.

In December 2020, a series of mudflows hit the town after days of heavy raining, destroying several houses.

[4] After 10 houses where damaged on 18 December, including the headquarters of the local SAR team,[5] a complete evacuation of the town was ordered.

There is a camping ground, facilities for campers, hotels, a swimming pool, a library, hospital, post office, liquor store, and other retail activity.

The nature reserve is home to a diverse range of wildlife, as well as catering for visitors and anyone wanting to explore the south side of the fjord.

The center is open to the public and houses an exhibition space, a library of artist books, and a bistro.

[17][18] Every week the car ferry MS Norröna of Smyril Line comes to Seyðisfjörður from Hirtshals in Denmark and Tórshavn in the Faroe Islands.
