Embark on a 9-day trek to Rush Lake in Nagar Valley, one of the world's highest alpine lakes and the highest in Pakistan at approximately 4,694 meters. This journey takes you from Islamabad through Babusar Pass and Hunza to Hopar, crossing dramatic glaciers, alpine pastures, and rugged mountain terrain beneath Spantik, Miar Peak, and Ultar Sar. Along the way, enjoy panoramic views, wild bird watching points, springs, and the changing beauty of golden meadows and crystal-clear waters. Moderately difficult and rewarding, the trek offers solitude, acclimatization, and some of the most breathtaking vistas in the Karakoram.
