The neighbourhood of Areskutan and the Dalarne highlands, owing to the railway and the development of communications by steamer on the numerous lakes, are visited by considerable numbers of travellers, both Swedish and foreign, in summer; but the northern heights, crossed only by a few unfrequented tracks, are known to few, and to a considerable extent, indeed, have not been closely explored.
The most important of these are the Dala Sandstone (chiefly developed in Dalarne), the Almasakra and Visingso series (around Lake Vetter) and the Dalsland formation (near Lake Vener).
The one is in the mountainous region of the south of Jemtland and the north of Dalarne, extending into Norway and thus lying in the middle of the peninsula about 62° N.
Some of the old wooden farm-buildings, especially in Dalarne, such as are preserved in Skansen Museum at Stockholm, are extremely picturesque.
The Gota canal route, however, is used by many; the uplands of Dalecarlia (Dalarne) are frequented; and the railway through the Jemtland highlands to Trondhjem gives access to a beautiful region, where numerous sanatoria are in favour with the Swedes themselves.
There are also upland mills in Dalarne and Vermland, and a considerable number in the neighbourhood of Gothenburg.
