The trail is separated in four portions--each representing approximately one week of hiking. The most popular part is by far the northernmost--between Abisko and Kebnekaise. The season, when the huts are open, usually runs between mid-June and the end of September, rowing boats are usually in place at the end of June or beginning of July, but the weather can be very treacherous, including late or early snow. The winter season runs from mid-February to the end of April.
