Karlsborgs båtklubb

Karlsborg is a small and peaceful guest harbour at the mouth of the Kalix River in Bottenviken, run as a club harbour by Karlsborgs båtklubb. It lies in the bay inside Tallgrund, east of the commercial harbour, and offers only a handful of guest berths within the larger small-boat marina – the atmosphere feels more local than commercial.

Guest berths are found on the pier heads, and the village itself is just 500 metres from the harbour.

A small island with a sandy beach shelters the harbour and creates an inviting sight as you sail in. Karlsborg carries a clear industrial heritage: the settlement grew up as a loading place and sawmill community, where the first steam sawmill, Lillsågen, was built in 1868, followed by a larger sawmill two years later. Going ashore, you can visit Erikön with its summer café and waffles, as well as Höganloft and Karlsborg's church from the early 1900s. It's a harbour for a quiet stop, a swim from the beach, and a walk among the traces of the mill town's history.
