Kungsleden, or "The King's Trail," is a renowned long-distance hiking trail in northern Sweden, stretching approximately 440 km through stunning wilderness. It is primarily accessible via public transport to its various trailheads, with the main hiking season running from late June to early September when mountain huts are open and snow has melted; winter travel is possible but requires advanced skills. Visitors can undertake solo or guided treks, with good physical fitness and navigation skills recommended for independent ventures. Typical visit duration varies from 4-7 days for popular sections (e.g., Abisko to Nikkaluokta) to 3-4 weeks for the entire trail, or shorter day hikes. Approximate costs include hut fees (around 400-500 SEK/night for non-members) or free wild camping, plus food and transport, potentially totaling 500-1500 SEK per day depending on choices. Be prepared for rapidly changing weather, carry appropriate gear, and plan food carefully as resupply points are scarce along some sections.
