Tsomgo Lake, written as Changu Lake, is a high-altitude glacial lake at an astounding elevation of 3,753 metres in the rugged East Sikkim district, inside a steep oval valley just kilometers from the international border, the crystal-clear waters are known for their unique ability to reflect changing shades, shifting from deep blue in summer to turquoise and solid white as winter freezes lock the surface into thick ice sheets. Driving further up the same high-security mountain corridor highway pass leads directly to the monumental Nathula Pass checkpoint, at a daunting altitude of 4,310 metres on the ancient Silk Road route, cutting directly through heavy military wire barricades separating India and China.

When to go

The recommended months to visit Tsomgo Lake are from April to May for pleasant daytimes, and October to November for clear dry mountain tracks.

Why visit

Both need permits arranged in Gangtok at least a day ahead through a registered agent, and Nathu La is open to Indian nationals only, on set days of the week. Tsomgo is at about 3,750 metres, which is a hard climb from Gangtok in one morning.

Cultural notes

Revered as a deeply sacred body of water by local indigenous Lepcha and Sikkimese Buddhist communities, the lake surface was traditionally used by ancient lamas to calculate seasonal weather omens. Nathula Pass historically formed a primary strategic node of the ancient Silk Road, facilitating trade caravans until its closure.

How to reach

Accessible exclusively from Gangtok via a rugged 54-kilometer uphill drive along a steep mountain highway pass. The route requires private or shared heavy multi-utility vehicles managed by experienced local mountain drivers.

Mizoram

Phawngpui (Blue Mountain)

Phawngpui, also called the Blue Mountain, is the highest peak in Mizoram at around 2,157 metres and the heart of Phawngpui National Park. Cloaked in rhododendrons, orchids and grassy slopes, it is sacred to the Mizo people and home to rare birds and the occasional serow and goral.

Meghalaya

Umiam Lake (Barapani)

Umiam Lake, popularly known as Barapani, is a large, sparkling reservoir set among pine-clad hills just north of Shillong in Meghalaya. Created by a dam on the Umiam river, it is a favourite spot for water sports, boating and photography, and a classic stop on the drive from Guwahati to Shillong.

Gujarat

Girnar Hills

The Girnar Hills rise outside Junagadh, an old volcanic range whose highest point, Gorakhnath Peak, reaches 1,031 metres — the highest in Gujarat. Wrapped in the dry-deciduous forest of the Gir landscape, the hills are a shared sacred site, with Jain marble temples and Hindu shrines near the top. Reaching them means either climbing a famous stairway of nearly 10,000 steps or taking the ropeway up over the forested valleys.

Gujarat

Kevadia (Ekta Nagar)

Kevadia, now officially Ekta Nagar, is home to the Statue of Unity — at 182 metres, the tallest statue in the world — on the banks of the Narmada River. Once a quiet settlement, it has been developed into a large tourism hub with theme gardens, a safari park, viewpoints and adventure activities.

Gujarat

Palitana (Shatrunjaya)

Palitana, in Gujarat's Saurashtra, is one of Jainism's most sacred sites — the Shatrunjaya hill is crowned by an astonishing cluster of over 800 intricately carved marble temples. Pilgrims climb roughly 3,800 steps to reach the summit, where the temple-city gleams in white marble. No one, not even priests, may stay overnight on the sacred hill.

Karnataka

Chikmagalur

Chikmagalur is the coffee heartland of Karnataka, a lush hill district in the Western Ghats where rolling estates, misty peaks and waterfalls draw a steady stream of young travellers from Bengaluru and beyond. It is a top weekend and workation pick for those wanting estate-stays, treks and great coffee within easy reach of a big city. Home to Mullayanagiri (Karnataka's highest peak), Baba Budangiri and dense shola forests, Chikmagalur blends gentle adventure with slow plantation living. Coffee homestays, trekking trails and cafe culture make it a favourite for couples, friend groups and remote workers.

Jammu & Kashmir

Gulmarg

Gulmarg is a bowl of meadow at 2,650 metres in the Pir Panjal, and it does two completely different jobs depending on the month. December to March it is the only serious ski resort in India. The Apharwat face has real off-piste terrain and the snow is dry enough to justify the trip. May to September the snow is gone and it is a meadow full of wildflowers with a golf course on it, one of the highest anywhere. The gondola climbs in two stages. The first, to Kongdoori, almost always runs. The second, up to just under four thousand metres on Apharwat, is frequently closed for wind and its tickets are capped daily — buy both stages early or accept that you may only get the first. If you are skiing off-piste, a guide is not optional. This is avalanche terrain and it has killed people.

Maharashtra

Bhimashankar

Bhimashankar, deep in the Sahyadri hills of Maharashtra, is one of the twelve Jyotirlingas of Lord Shiva and the source of the Bhima River. Surrounded by a wildlife sanctuary that shelters the rare Indian giant squirrel, it combines a major pilgrimage with lush Western Ghats trekking.

Leh & Ladakh

Tso Moriri

Tso Moriri, or Mountain Lake, is an offbeat high-altitude lake tucked away at an astounding elevation of 4,522 metres on the Changtang plateau of southeastern Ladakh. The body of water spans roughly 19 kilometers in length and is entirely fed by glacial meltwater from surrounding snow peaks exceeding 6,000 metres. It is protected under international environmental treaties as part of the Tso Moriri Wetland Conservation Reserve. Unlike Pangong Tso, Tso Moriri is far quieter, less commercialized, and rawer for it. The cobalt-blue waters are flanked by the small nomadic settlement of Korzok, which houses an ancient mud-brick monastery. The surrounding marshy wetlands provide sanctuary to rare and endangered Himalayan migratory birds.

Maharashtra

Devbagh & Tarkarli Sangam

Near Malvan, the Devbagh sandbar where the Karli River meets the sea has scuba diving, dolphin trips and the clearest water on the Konkan. The best months to visit are roughly November to February, when seas are calm and skies are clear; the monsoon (June to September) brings rough water and many beach shacks shut. Plan water sports and swimming for the dry winter window.

Assam

Kaziranga National Park

Kaziranga National Park is a vital wildlife conservation sanctuary spanning over 430 square kilometers of alluvial floodplains along the southern banks of the Brahmaputra River in Assam. The unique landscape comprises a dense marshy terrain dominated by towering elephant grass, shallow reed swamps, and open sal forest canopies. The national park is known for hosting over two-thirds of the world's entire surviving population of the endangered Great Indian One-Horned Rhinoceros. The reserve floor operates under strict environmental regulations, split systematically into four safari ranges. Bagori range remains popular for early morning elephant-back safaris, allowing close, safe tracking lines to observe rhinos grazing peacefully in the high morning mists.

Leh & Ladakh

Zanskar Valley

Zanskar is one of the last genuinely difficult journeys left in India, and that is the whole appeal. The valley is cut off by snow for around seven months of the year. In summer a single road comes in over the Pensi La from Kargil, and it is long, rough and worth every hour of it. Padum is the only real settlement. Phuktal monastery is built into a cliff cave above a river and takes a walk of several hours to reach — there is no road to it, which is why it feels the way it does. In deep winter, when the road closes, the frozen Zanskar river itself becomes the route: the Chadar trek, walked on the ice in temperatures well below freezing. It is a serious undertaking, not a holiday, and it needs a proper operator and real cold-weather experience. It has also become less reliable as winters warm, and trips are cancelled. If you are coming in summer, budget more days than the distance suggests. Landslides close the road, and there is no alternative route. July to early September for the road. Late January and February for the ice.

Trending in Sikkim

Gangtok

Gangtok

Gangtok is where most Sikkim trips begin, and its real value is as a base rather than a destination. The town itself is a steep ridge of concrete with one pleasant pedestrian street, MG Marg, where no vehicles and no spitting are allowed and the whole town walks in the evening. Rumtek monastery, half an hour out, is the seat of the Karma Kagyu lineage and the more worthwhile hour. Enchey, closer in, is quieter still. Tsomgo lake and Nathu La are the standard day trip. Both need permits arranged through a registered operator in Gangtok, both are high — Tsomgo is at around 3,700 metres — and Nathu La is closed to foreign nationals entirely. If you have only been in the hills a day, that altitude gain in a single drive is a lot. For actual Sikkim, keep going. Pelling for the Kanchenjunga view, Yuksom for the walking, north Sikkim for Lachung and the Yumthang valley — all of which need their own permits. March to May and October to early December. The monsoon here brings serious landslides and roads close for days at a time.

Yumthang Valley

Yumthang Valley

Yumthang Valley, often called the Valley of Flowers of Sikkim, is an alpine meadow at around 3,500 metres in North Sikkim. In spring its slopes blaze with rhododendrons and primulas, and there are hot springs, the Shingba Rhododendron Sanctuary, and Zero Point higher up.

Rumtek Monastery

Rumtek Monastery

Rumtek is the largest monastery in Sikkim and the seat-in-exile of the Karmapa, head of the Karma Kagyu (Black Hat) lineage. Rebuilt in the 1960s by the 16th Karmapa as a faithful copy of Tibet's Tsurphu monastery, it holds the Golden Stupa with his relics, a monastic college, and treasures of the lineage. Ritual dances, deep-horn ensembles and the view back across the valley to Gangtok make it the centrepiece of any Sikkim circuit.
