Borovets is a town on the northern slopes of Bulgaria’s Rila Mountains. It’s the gateway to numerous ski and snowboard runs on Rila National Park’s craggy Musala Ridge. Cycle routes crisscross the alpine landscape. Footpaths lead through rocky outcrops and valleys to the 7 high-altitude Musala Lakes, including glacial Icy Lake. Just north, kayaks and other leisure boats ply the Iskar Reservoir’s calm waters.
