Rara Lake Nepal: The Hidden Treasure of Mugu

Located in the isolated far-western part of Nepal, Rara Lake is one of the most spectacular natural wonders of the country. Rara Lake is the largest and deepest lake in Nepal with crystal blue water that changes color with light and season. Surrounded by serene hills and woodlands; quiet, clean and away from the hustle and bustle of modern life.

Rara Lake is excellent spot for trekkers, nature lovers, wildlife enthusiasts and anyone seeking peace and quiet in the mountains. It’s a bit of a trek to get there, but the scenery is amazing and the serenity is something you won’t forget.

What is Rara Lake?

Rara Lake, also known as Mahendra Tal or Mahendra Rara Lake, is Nepal’s largest lake. The lake is situated at an elevation of around 2,990 metres (9,810 ft) above sea level and occupies an area estimated to be 10.8 square kilometres (4.2 sq mi). It has a maximum depth of 167 metres (548 ft) and is one of the deepest lakes in South Asia.

The lake is the centrepiece of Rara National Park, Nepal’s smallest national park though one of its most naturally rich. The park has an area of around 106 square kilometers and contains a rich diversity of flora and fauna including Himalayan black bear, red panda, musk deer, grey wolf, leopard and hundreds of species of birds.

The waters of the lake are infamously crystal-like pure – so clear that in the shallower parts you can often see right down to the bottom of the lake. The surrounding forests of pine, oak and rhododendron add to the other-worldly beauty of the area, making Rara Lake look more like a dream than actually a real tourist attraction.

Quick Facts About Rara Lake

Where is Rara Lake Located in Nepal?

1. Which District is Rara Lake Located In?

Rara is located in Mugu district, one of the most disconnected and least developed districts of Nepal. Mugu is one of the districts of Karnali Province (Province No. 6) in the far-western region of the country.

2. Where is Rara Lake on the Map of Nepal?

Rara Lake is located in the far north-west of Nepal, close to the border to Tibet, and not too far away from the districts of Humla and Jumla on a map. Gamgadhi, the district headquarter of Mugu is the nearest town of importance and is only a few kilometres from the lake. The lake is possibly 400-450 km north-west of Kathmandu in a straight line, however the distance traveled by road and trek is much further.

Why is Rara Lake Famous?

Rara Lake is famous for several remarkable reasons:

Nepal’s Largest Lake:

Rara is the biggest lake in Nepal. The huge, calm surface acts like a mirror to the surrounding mountains and sky, a stunning sight which photographers and artists can not resist.

Exceptional Water Clarity:

The lake’s water is clean and unpolluted, thanks to the national park that surrounds it. The colours shift throughout the day – delicate silver in the morning, dazzling turquoise in the midday sun, and deep purple and gold at dusk.

Incredible Biodiversity:

Rara National Park is the habitat of more than 200 species of birds, many of which are unique migrants that take advantage of the lake as a habitation area. The trees that surround it provide a place of safety for an astonishing list of endangered wildlife species.

Remote and Unspoiled:

Unlike the heavily explored routes of the Annapurna or Everest regions, Rara Lake is remarkably uncrowded. The challenge of getting there is a natural filter, keeping the natural environment preserved and the experience personalized.

Cultural Significance:

The lake is of spiritual importance to the surrounding communities. It is named after the Hindu god Mahendra (another name for Indra) and the surrounding towns have lived in peace with the lake and forest for ages.

A Hidden Treasure of Nepal:

Rara is a hidden jewel, acknowledged by travel authors and adventurers as one of Nepal’s best kept secrets, where you may enjoy the advantages of a major Himalayan destination without the crowds and commercialisation.

How to Get to Rara Lake from Kathmandu?

Option 1: By Air (Fastest Route)

Kathmandu → Nepalgunj → Talcha Airport → Trek to Rara Lake

This is the most popular and practical route for most travellers.

Step 1: Fly Kathmandu to Nepalgunj

Domestic flight from Tribhuvan International Airport, Kathmandu to Nepalgunj Airport. This route is served by various airlines like Buddha Air and Yeti Airlines on a daily basis. Flight time is about 1 hour. Nepalgunj is one of the main hubs of far western Nepal and the gateway to the Karnali area.

Step 2: Fly Nepalgunj to Talcha

Getting to Rara Lake From Nepalgunj, take a small plane (usually a 9–19 seater Twin Otter or equivalent) to Talcha Airport (IATA: RHP), the nearest airport to Rara Lake. The trip takes around 45 minutes and gives spectacular aerial views of the foothills of the Himalayas and the Karnali river basin. Please note that Talcha Airport is weather dependent and flights are often delayed or cancelled, especially during monsoon and winter months. Always have buffer days in your plan.

Step 3: Trek from Talcha to Rara Lake

It is a reasonably short journey (2-3 hours, about 10-12 km) from Talcha Airport to the lake. The path is through forest in Rara National Park, and provides an amazing introduction to the scenery.

Option 2: By Road + Short Trek (Budget Route)

Kathmandu → Surkhet/Jumla (by bus or jeep) → Trek to Rara

This is a more difficult but far less expensive solution. Or you can drive some of the way and then hike.

Kathmandu to Surkhet: 15 hours via bus or 10 hours by jeep via Prithvi Highway and Midhill Highway. From Surkhet you can head off by jeep to Jumla (another 8–10 hours on hard mountain road), the standard trekking/starting point for Rara Lake.

Jumla to Rara Lake Trek: The classic journey from Jumla to Rara Lake involves 4–5 days one way (about 90–100 km total round trip), through magnificent mountain scenery, traditional Jumla settlements and dense national park forest.

Option 3: Helicopter (Most Comfortable & Expensive)

If you have less time but a flexible budget, you can rent a helicopter directly from Kathmandu or Nepalgunj to Rara Lake. Rara helicopter tours offer stunning flights over the Himalayas, with landings on the northern or western shores of Rara Lake (depending on weather and pilot discretion). This is a popular choice for luxury visitors or those who combine the trip with a helicopter tour of Nepal’s remote west.

All the trekkers and travellers who want to reach the Rara lake by drive and heli also need to secure the permits. This are the permits you need for visiting Rara Lake:

How Difficult is the Rara Lake Trek in Nepal?

The Rara Lake Trek is generally rated moderate to moderately challenging, though the remoteness of the region adds an element of difficulty that should not be underestimated.

Trekking Highlights:

• Daily walking time: 5–7 hours per day
• Maximum elevation: Around 3,500–4,000 metres on some route variations (passes can be higher)
• Trail conditions: Mix of well-worn trails and rougher mountain paths; some sections can be icy or muddy depending on season
• Accommodation: Basic teahouses and lodges; facilities are more rustic than in popular trekking regions
• Fitness requirement: Moderate to good fitness is recommended; prior trekking experience in mountain terrain is helpful

Challenges to be aware of:

• Altitude: Rara Lake sits around 3,000 metres but during trek you need to cross the Jaljala Pass which stands at the altitude of 3,580 meters. So chances of risk are high due to crossing passes where trekkers can experience AMS symptoms when not acclimatised properly.
• Remoteness: Due to remote location here the medical facility is limited due to lack of modern hospital. So travel insurance with helicopter evacuation cover is needed.
• Weather: The weather can change quickly and the trail might be hazardous or snow-covered in winter months
• Logistics: There are few teahouses compared to other famous hiking places in Nepal, therefore it is recommended to pack some additional supplies.

First-timers: A licensed local guide who understands the trail, teahouses and the area is strongly recommended. This also benefits the local economy of one of Nepal’s poorest regions, as well as for your safety.

What is the Best Time to Visit Rara Lake?

• Spring (March–May): This is one of the best seasons to visit Rara Lake. The weather is warm and stable, rhododendron forests erupt in vibrant reds and pinks, and the lake sparkles with reflections of clear blue skies. Wildlife is busy and birdlife is most diversified. Highly recommended.
• Summer/Monsoon (June–August): Heavy monsoon rains, leeches on the trail, and the threat of landslides that can close roads and pathways. Talcha flights are regularly cancelled. The landscape is green and beautiful, but the conditions are harsh. Usually not recommended
• Autumn (September–November): The most popular season for trekking and visiting Rara Lake is during this time. The good reason is the skies are crystal bright after the monsoon, the air is fresh and the lake reflects the surrounding mountains in magnificent form. Temperatures are pleasant. It’s the perfect time to visit Rara Lake in Nepal.
• Winter (December–February): Rara Lake in winter is hauntingly beautiful, frequently partially frozen and surrounded by snowfields, but difficult to reach. Night temperatures plummet well below zero, aircraft may be grounded for weeks at a time, and some teahouses close. Suitable for experienced trekkers in cold weather with the right gear.

Overall best months: October, November, March, April, and May.

Weather Forecast at Rara Lake

Rara Lake is situated at an altitude of approximately three thousand metres and the weather is unpredictable at any time of the year. Always consult a trustworthy mountain weather forecast service before starting your journey.

• Windy.com – Excellent for wind and precipitation forecasting
• meteoblue.com – Provides high-altitude forecasts for specific coordinates
• Nepal Department of Hydrology and Meteorology (DHM) – dhm.gov.np – Official Nepal weather authority
• Mountain Forecast – mountain-forecast.com – Specialised elevation-based forecasts

Once you’re on the route, check the forecast every day and be prepared to delay or change your plans if severe weather is in the forecast. Ask your guide for local information – they usually know micro-weather trends better than any app.

Can You Swim in Rara Lake?

You can swim in Rara Lake technically, however it is generally not advised due to various reasons:

1. Conservation rules: Rara National Park has strict environmental regulations, and activities that could disturb the ecosystem (including swimming )are restricted. Always check current rules with park authorities.
2. Water temperature: Even in summer, the water is very cold — typically 10–15°C — and can cause cold shock or hypothermia.
3. Depth: The lake drops rapidly in depth, reaching 167 metres at its deepest. There are no lifeguards or rescue services.

Most people are happy to enjoy the beauty of the lake from the shore, go for boat trips when available and enjoy the reflection and the calm rather than swimming.

Who Died in Rara Lake? A Dark Chapter in Nepal’s History

The most sensitive chapter in the history of Rara Lake is the sad displacement of two whole villages, Rara village and Chapra village, on the coast of the lake.

The government chose to shift the communities residing inside the park limits to conserve nature when Rara National Park was formed in 1976. The villagers, primarily Thakuri and Brahmin, were forcibly evicted and resettled in Bardia District, in the far south of Nepal, a totally different ecological and climatic zone from the high-altitude world they were used to.

The move was huge. Many of the locals who were used to the cool mountain air of Mugu could not adjust to the scorching lowland temperature of Bardia. In the years after the move, several died from malaria, heat-related disease and the psychological pain of being torn from their ancestral homes. Some stories claim that a substantial part of the transplanted group died in the first few years.

This terrible occurrence is a sore memory for survivors and descendants, and raises critical considerations about the human cost of conservation programs that do not take into account the rights and wellbeing of local communities. Today, the banks of Rara Lake lie silent where villages once existed – a beauty grown out of grief in part.
