In the remote spot of the Lahaul Valley of Himachal lies the little known town of Sissu. What qualifies this town to be taken out of obscurity are the two natural marvels it gracefully houses within its limits, namely, Sissu Lake and Sissu Waterfall. Both these natural wonders share the same vicinity and are thus within reach of each other near the Atal Tunnel, at once marking this offbeat station accessible throughout the year. The lake shimmers amid the Chandra River’s flow, framed by snow-capped peaks hovering all around it. Nearby, the waterfall tumbles dramatically from Himalayan glaciers, offering an exhilarating spectacle. Even in 2025, Sissu continues to grow in popularity, drawing more and more travellers who seek ethereal mountain experiences, seasonal adventure and a reunion with nature.
Sissu has a reputation as being a small, idyllic town perched at about 3,120 m above sea and flung some 40 km from Manali in the Lahaul and Spiti district. Once a remote hamlet, it has gained a substantial prominence ever since the opening of Atal Tunnel in 2020. The town overlooks the confluence of the Chandra River and the glacial flows that feed both the lake and the waterfall. Another feather in the cap of Sissu is the Raja Gyephang temple which it houses, a local shrine that acts as an insightful window into the region's spiritual traditions.
The meltwater-formed waterfall plunges around 50 m into a deep valley. It is located close to Sissu hamlet, just off the Leh–Manali highway—you can’t miss it. Visitors can get up close enough to feel the misty spittles of the waterfall and hear mist-laden echoes against rocky cliffs by hiking a short 2-km wooded trail. The adjacent willow and pine forests enhance the picturesque ambience of the spot, fostering a tranquil setting ideal for adventurers and nature enthusiasts.
Perched at over 3,000 m and situated about 3 km from the waterfall is the majestic wonder called the Sissu Lake. It is fed by the same glacial streams that honour the waterfall and during winter season, the temperature drops as low as -15 degrees, freezing its clear waters to look like the emerald eye of the earth—a seasonal phenomenon that draws throngs of photographers and ice-travel tourists alike. In summer, the lake’s calm surface mirrors surrounding peaks, making for an ideal tranquil spot for walking, picnics, or meditation.
While visually as charming a sight as a cinematic scene, Sissu’s appeal extends beyond sightseeing. The waterfall trek is short but rewarding, with rough terrain lending to moderate effort. Furthermore, lake-side camping allows immersive star-gazing Himalayan experiences under sky like a star-studded quilt. The region also serves as a launch-pad for longer treks—such as to Ghepan Lake or over Baralacha Pass. Winter visitors can also engage in wholesome snow-based activities like skiing or ice exploration.
The town retains a certain Lahauli-Tibetan character of community that lends it more cultural colour. The Raja Gyephang temple, which displays regional Buddhist culture, is a major highlight. At homestays or little tea booths, you must ensure you try regional fares like thukpa, momos, and butter tea. Engaging with villagers offers pertinent perspectives on high-altitude living, hospitality, and the exchange of traditional knowledge.
Sissu is accessible via road through the Atal Tunnel from Manali—around a 1.5-hour drive. The nearest airport lies in Bhuntar, 90 km away.
