It offers a less crowded route with equally stunning mountain scenery and significant opportunities for acclimatization. The trek typically starts from Lukla, following a route up to Namche Bazaar and then branching off towards the lakes. The highlight of the trek includes reaching Gokyo Ri (5,357 meters), a peak that provides one of the best panoramic views of Everest, Lhotse, Makalu, and Cho Oyu.

• Biodiversity and Environmental Significance: The region around the Gokyo Lakes is rich in biodiversity despite its high altitude. The area is home to a variety of flora and fauna adapted to the cold and harsh environment. Notable wildlife includes the snow leopard, Himalayan tahr, and several species of pheasants. The lakes themselves play a critical role in the local hydrology, acting as reservoirs for downstream rivers.

• Cultural Importance: The Gokyo Lakes are considered sacred by both Hindus and Buddhists. The site is a venue for pilgrimages during the Janai Purnima festival, where hundreds of pilgrims visit the lakes to cleanse themselves spiritually. The presence of Gokyo Village near the third lake also highlights the local Sherpa culture, offering visitors a glimpse into the lifestyle and traditions of the high Himalayas.
