Map

The Gosaikunda Helambu Trek is a 12-day moderate trek combining the sacred pilgrimage site of Gosaikunda Lake (4,380m) with the culturally rich Helambu valley, homeland of the Hyolmo (Helambu Sherpa) people. The trek begins with a drive from Kathmandu to Dhunche, climbs to Gosaikunda for the pilgrimage experience, crosses the Laurebina La Pass (4,610m), then descends through the Helambu valley visiting traditional Sherpa villages, monasteries, and terraced farmland. The Helambu region is known for its apple orchards, traditional Sherpa architecture, and the Hyolmo culture which is distinct from the Sherpa of the Everest region. The trek is accessible year-round and offers an excellent combination of natural beauty, religious significance, and cultural immersion within easy reach of Kathmandu.
