Travel to Koster

You can travel to the Koster Islands with your own boat or take the passenger boat that departs daily from Strömstad Northern Harbour, in the middle of the city all year around.It can be difficult to find parking in the city centre during the summer, we recommend that you park your car at one of our long-term parking spaces and use the parking-buses that take back to the harbour, cost-free.

In connection to the Koster ferries, in the same building as Strömstad Infocenter, you will find the waiting hall.

Bring your own bike or kayak:

If you would like to bring your own bike, please note that there are many people traveling with the Koster ferries during the high season of summer and space for bikes or kayaks may be limited. This could possibly mean that you may have to wait for a later departure. The fee for bringing a bike on board is 90 SEK kr, turn and return. The fee for a kayak is 180 SEK kr, one way. Payment for a bike or a kayak can only be made on board and not through the ticket automats or in the Västtrafik To Go-app.

Dogs on board:

Dogs are very welcome on board the Koster ferries, but out of respect for other passengers with allergies, they are referred to the outdoors seating areas.

Parking and free parking-buss to the city centre:

Strömstad gets a lot of visitors during the summer and vacant parking spaces can be difficult to come by. Our recommendation is to park your car or vehicle at one of the long-term parking places.
Parking fee; SEK 40 / per day / 6-31 / 8.

Free buses are running during summertime (June-August) that go all the long-term parking places and back to Strömstad square where the ferries depart from.
