Enjoy a full-day hike of the Rila National Park and conquer the summit of Musala, the highest mountain on the Balkan peninsula Boasting more than 180 glacial lakes, the name of the mountain is of Thracian origin and means “Plenty of Water.” Coniferous trees grow up to 170-200 feet (50-60 meters) tall, concealing diverse wildlife that includes bears, wolves, wild goats, and imperial eagles. Following a pick-up in Plovdiv, head towards Borovets, Bulgaria's oldest ski resort. The 19th-century resort is surrounded by old pine forests, and boasts one of the healthiest climates in Bulgaria. Board the gondola lift to the peak of Yastrebet (7,936 feet/2,369 meters) for the start of your trek. Your guide will lead you along the trail to the Musala Mountain Hut, and on to a stunning lake, before hiking to Icy Lake (9,078 feet/2,710 meters), the coldest and highest lake in the Rila Mountains. A short but steep ascent follows all the way to Musala’s summit (9,799 feet/2,925 meters), with spectacular vistas along the way. Gaze across at the alpine Pirin Mountains, Vitosha Mountain, Sredna Gora Mountains, and the green carpets of the Rhodope Mountains. After a break at the summit, hike back down, retracing your steps to the gondola lift and on to Borovets for the transfer back to Plovdiv.
