Known as the “land of a thousand lakes”, Mazury is one of the best kayaking spots in Europe. The hundreds of kilometres of signposted trails can keep you paddling for days, through sun-dappled forests and lakes filled with swans. The best known is the Krutynia Trail, which begins near the village of Sorkwity and ends 115km later in the town of Ruciana-Nida. A number of companies rent kayaks and canoes; the English-speaking AS Tour (89/742 1430, www.masuria-canoeing.com) rents boats from 20zł per day, and offers a pick-up and drop-off service. Stay at campsites scattered along the kayak trails, or in village guesthouses en route – the tourist office can help with this.
