MTB Four Islands

Book your stay

Make granite and rocks your paths!

MTB cycling on the Swedish west coast is an amazing experience. You are never far from the ocean. The granite and rocks become your paths and you end the day with a swim at sunset.

Four islands in one tour!

This MTB route heads straight westwards from Lagunen. The goal is to ride on four different islands, which offer an optimal mix of woodland, ocean and rocks. The islands are connected by high bridges or viaducts. The best views are from the bridge between Öddö and Tjärnö. This route also includes tarmacked and gravel roads through a traditional cultural heritage landscape. Mid-trip you can visit the Tjärnö Marine Laboratory. Their aquarium is open to the public in summer; however groups can book visits all year round.

Parts of the route are technical, but you can always get off the bike and walk.

Approximate duration

We recommend allowing half a day. This leaves enough time for a swim and a coffee break.


This route is 43 km long and has only gentle slopes and climbs.


No markings. You ride on paths, gravel roads and sealed roads. Use an app and download the GPX file.

Which map application do you use?

Lagunen has decided to focus on three apps, which we find work well in our area. All have useful free versions available, although a paid subscription obviously means more features. You can also download the GPX file to your own favourite app. In addition, our reception sells a useful leisure map, scale 1:50,000.

  • Viewranger: This app has a good user interface and useful map functions. Originally designed for hiking and navigating in forests and nature. Easy to create trips and plan routes. We use it mainly for hiking and trail riding. Integrates with Openstreetmap, which is very up-to-date in our area.
  • Trailforks: This is home turf for trail riders. The app is a meeting place for anyone who enjoys cycling in woodland. Free maps make it easy to find good trail riding routes.
  • Strava: This app has been around for a long time and has many users in our area. This means that it is very up-to-date and includes recommendations for both road cycling and mountain biking.

Stay near the archipelago of Strömstad

At Lagunen you stay right by the ocean, where the Strömstad archipelago begins. The site has lots to enjoy and discover. Will you spend the day exploring Strömstad, enjoying a boat trip on Kosterhavet, or relaxing and catching crabs from Mali’s jetty, right next to Lagunen’s own beach? At Lagunen you wake to the sound of lapping waves, shrieking seagulls and the sea breeze from Kosterhavet, which finds its way into the bay all year round – what time you wake up is up to you.
