The Koster Islands

Visiting the Koster Islands can be a really lovely excursion! The scenic Koster Islands are located just outside Strömstad, close to the border with Norway. Here you can cycle, hike, swim or enjoy good food in nice restaurants. Here you will also find the Kosterhavet National Park - Sweden's first marine national park.

The Islands offer a rare sense of peaceful, unspoilt coastal wilderness, dramatic granite cliffs and sweeping sea views. It’s a place to slow down and enjoy simple Scandinavian pleasures – cycling or hiking between villages, swimming and savouring fresh seafood in a relaxed, authentic setting.
