Gosaikunda is a high-altitude alpine freshwater lake in Nepal's Langtang National Park, revered by Hindus as the abode of Lord Shiva and Goddess Gauri. The trek to Gosaikunda is challenging due to the high altitude (over 4,300 meters), so acclimatization is essential. Accessibility is limited to trekking, and physical fitness is required. While solo trekking is possible, hiring a guide is recommended for safety and navigation. The best time to visit is during the pre-monsoon (April-May) and post-monsoon (September-October) seasons to avoid heavy rains and snow. The trek typically takes 6-7 days and can cost between $500-$1000 USD depending on the level of comfort and services chosen, including permits, accommodation, food, and guide fees. Altitude sickness is a serious concern, so carrying appropriate medication and consulting a doctor before the trek is advised.
