Holmön, which calls itself the sunniest place in Sweden, is a 15km-long offshore island with a boat museum and a collection of traditional craft, plus a good quayside restaurant and swimming beaches. In July there's a rowboat race to Finland, which is only 36km away. Free ferries depart two to three times daily from Norrfjärden, 26km northeast of Umeå (bus 118 or 119).
