St Kilda is a set of islands where a beautiful natural habitat has been able to develop and adapt over millions of years, then providing support for a community and culture to grow over thousands of years.

This remote archipelago is part of the Outer Hebrides islands, sitting to the north west of North Uist. St Kilda is composed of five islands, Hirta, Dùn, Soay, Boreray and Levenish, alongside a number of sea stacks and islets. It’s a place of rare beauty and drama.

But the remoteness of these islands didn’t hold progress back - people lived and thrived on these islands, just as they did on the main Outer Hebridean islands, sharing a distinctive culture.

St Kilda is remarkable not just for its striking landscape and unique human story. It’s unique geographical position and oceanic climate allow it to support a dazzling array of inter-dependent ecosystems. An extraordinary biodiversity can be observed, both on its windswept lands and beneath the sparkling surface of its coastal waters. The world heritage site is 95% marine and the seabird colonies are the most important in the north-east Atlantic.

Why You Should Visit

As one of the main aims of Scotland’s UNESCO Trail is sustainable holidays and visits, we’d recommend learning about St Kilda from some of the attractions and exhibitions on the main Outer Hebridean islands.

St Kilda is a stunning and beautiful place which can be an amazing experience, but the culture and history of this group of islands is reflected in the wider Hebridean community.

The heritage site is a protected environment, so it cannot accommodate a large number of visitors. Tours by boat are available but availability is strictly controlled.

It’s hoped in the future that a visitor centre will be developed on the main islands and work is underway within the Outer Hebridean communities to make this ambition a reality.

If you do explore the islands directly, you’ll have a rare experience of walking through a landscape abandoned by the entire community in 1930. You’ll also visit preserved archaeological sites and relics, which reveal the close relationship the islanders had with their unique natural environment, and how they adapted to outside influences. You’ll see this in the remnants of houses, enclosures and cleits – drystone storage structures – remnants of World War I guns and communications.

The cultural landscape of St Kilda shows a long occupation of the islands and a skill and resilience to live there.”

United Nations Sustainable Development Goals

The Sustainable Development Goals (SDGs) are an urgent call for action of a global partnership of countries. They recognise that ending poverty and other deprivations works hand-in-hand with strategies to improve health and education, reduce inequality and encourage economic growth, alongside tackling climate change.

All of our UNESCO designations work towards the UN SDGs – this is looking at their work towards three in particular.

Goal 14

Life below water

The Marine Protected Area around St Kilda ensures there is a healthy marine ecosystem that supports marine life, from the smallest organism to the larger sea mammals, and ensures the seabirds that come to St Kilda are able to raise their young.

Goal 15

Life on land

The management of St Kilda protects the biodiversity of the archipelago and recognises conservation as a top priority in land management. This ensures both habitats and species are protected.

Goal 17

Partnership for the goals

St Kilda works with UNESCO to find solutions to common problems, share best practice, and support one another to achieve the UN Goals.

Learn more about UNESCO

St Kilda is one of Scotland’s six World Heritage Sites. It is the UK’s only dual UNESCO World Heritage Site, and one of only 39 in the world.

It was made a World Heritage Site in 1986 for its natural heritage, but this was extended in 2004/5 to include the surrounding marine environment and its importance as a cultural landscape.

St Kilda is also a national nature reserve, national scenic area, site of special scientific interest and a European Union special protection area.

When you visit

You can learn more about St Kilda and the Outer Hebrides culture and history at a number of attractions including museums and art centres. Our Outer Hebrides journey takes you around a number of places to visit including Seallam!, Taigh Chearsabhagh and the Museum nan Eilean where you can experience what island life is like, and how the landscape, language, culture and heritage are so important here.

If you do decide to visit St Kilda, please ensure you tread lightly and choose companies who operate responsibly through sustainable practices and being mindful of nature and wildlife.

Many of the boat tour operators who run tours to and around St Kilda have strong ties to the islands, some of them ancestral, and are more than willing to share their own stories and the authentic culture of the islands with passengers.

The islands were evacuated on 29 August 1930, when the remaining 36 islanders voted to leave as their way of life was no longer sustainable.

Now St Kilda is inhabited by just a few staff members of the National Trust for Scotland and Ministry of Defence and a handful of researchers.

But those wishing to extend their day-trip to the island, can book into a short-term campsite on the largest island of Hirta which accommodates up to six people.

If you visit St Kilda, a great place to begin is the small museum housed inside the refurbished 19th century houses on The Street of Hirta. Inside you’ll find artefacts ranging from pottery and textiles, to agricultural implements, attire and personal items; all which offer a glimpse into what life was like in days gone by.

How to visit

Lying 41 miles off the west coast of Benbecula, the archipelago of St Kilda is a far-flung Atlantic destination which can only be reached by the water, either in your own vessel or with a chartered tour company. Day trips are available from the islands of Harris, Skye and Uist.

Travelling to the Outer Hebrides is easier than you might think. Flights are available to Stornoway or Benbecula with Loganair, or you can reach the islands from the mainland by ferry. Caledonian MacBrayne (CalMac) operates ferries from Oban, Mallaig, Uig and Ullapool on Scotland's west coast.
