Norway has excellent hiking maps or “Turkart” published by the DNT (Norwegian Trekking Association). These topography maps cover all areas of the country and the majority come in the following scales: 1:25,000, 1:50,000, and 1:100,000. For hiking and other outdoor pursuits, the DNT maps have everything you need including the trails, huts, and estimated times. They are pricey, costing about $24 USD each, but are excellent maps and have a light plastic coating that is great for the outdoors.
Surprisingly, Norway has not set up an online store for people outside of the Nordic countries to order DNT maps. The DNT Oslo online store allows you to browse the maps, but for shipping outside Norway, Sweden, Denmark, and Finland, you must email your shipping information and the requested maps to [email protected]. Of course, the DNT office will be efficient and helpful over email.
If you don’t mind waiting until you arrive in Norway to buy maps, the DNT Oslo (located downtown at Storgata 3) has all country maps and staff on hand to answer questions. When traveling in other parts of the country, many of the accommodations, tourist-related businesses, and even grocery stores will sell maps specific to that area.
