Ferries from Idö (Arholma) brygga

Idö's two calls are 6 to 9 minutes apart and neither leads to the mainland. Östersjö brygga takes 8 to 11 minutes, Tyvö 6 to 7, with eight sailings a week on one and seven on the other, running from 12:36 in the middle of the day to 20:39 at night.

Four day patterns on the first leg and three on the second is a lot of variation for a route with fifteen sailings in total — most weekdays here have their own timetable.

Idö belongs to the Arholma group at the northern edge of the Stockholm archipelago, where the islands are small, low and close together, and Waxholmsbolaget threads a single boat between them rather than running a fixed shuttle. Nothing departs before midday, which places this among the routes serving people already on the islands rather than anyone arriving for the day.
