Most people picture Nepal as snowy peaks and steep passes. Rara Lake is something else. It’s a huge, deep-blue lake at about 2,990 m, wrapped in pine forest, in a corner of far western Nepal that few travelers ever see. It’s the largest lake in the country, and on many days you’ll share it with almost no one.
Getting there takes a little effort. You’ll need a domestic flight (or a long road trip) and a few days of easy hiking. But that’s exactly why it’s quiet, and why people who go often call it their favorite place in Nepal. Here’s what to know before you plan your trip.
Quick Answer
Rara Lake (also called Mahendra Tal) is Nepal’s largest lake, covering about 10.8 km² and reaching about 167 m deep. It sits inside Rara National Park in Mugu District. Most trips take 7 to 14 days, are rated moderate or easy to moderate, and stay below about 3,700 m. The best seasons are March–May and September–November.
Rara Lake at a Glance

Why Rara Is Worth It
- It’s Nepal’s largest lake. Crystal-clear water, forest, and ridges make it look more like an alpine postcard than a typical Nepal view.
- It’s quiet. One operator says the lake sees only a few hundred trekkers a year. You’ll often have the trail to yourself.
- It’s accessible. Most routes stay below about 3,700 m, so altitude is less of a concern than on high treks.
- It’s a national park. Rara National Park has dense forests of pine, spruce, and rhododendron, and many bird species. Reports mention wildlife such as musk deer and Himalayan black bear, though you shouldn’t count on seeing them.
- It feels untouched. The area has no road to the lake itself. You walk in from Talcha or Jumla.
How to Get to Rara Lake
By air (the most common way). Fly from Kathmandu to Nepalgunj (about 45 minutes), then take a small plane to Talcha (about 30 minutes). From Talcha, it’s about 2 to 3 hours on foot to the lake. Some trips fly to Jumla instead and trek for several days to the lake.
By road. A longer option drives from Kathmandu to Surkhet, then up the Karnali Highway to Talcha. One operator’s by-road plan takes 12 days in total. It’s cheaper on flights but long and bumpy, so it suits adventurous travelers.
Weather matters. Flights to Talcha and Jumla depend on clear skies, so keep a spare day in your plans.
What a Typical Trip Looks Like
Here’s a common outline. Exact stops vary by operator and route.
| Day | Plan |
|---|---|
| 1 | Fly Kathmandu → Nepalgunj |
| 2 | Fly Nepalgunj → Talcha, trek to Rara Lake (about 2–3 hrs) |
| 3 | Explore the lake and hike to Murma Top for views |
| 4 | Relax, walk around the lake, or hike in the forest |
| 5 | Return to Talcha |
| 6 | Fly Talcha → Nepalgunj → Kathmandu |
Longer versions add days around the lake, a visit to Ghorasinga (about 3,050 m), or a trek starting in Jumla.
Difficulty and Altitude
Rara is generally rated easy to moderate. Walking days are mostly 2 to 6 hours, on forest trails with gentle climbs. The lake sits at about 2,990 m, and the maximum height on most routes is about 3,050 m to 3,700 m, depending on whether you climb Murma Top.
Altitude illness is less likely than on higher treks, but it can still happen, especially at the lake. Go slowly, drink water, and tell your guide about any headache, nausea, or dizziness. Never go higher with symptoms. For details, read our altitude sickness guide.
Best Time to Go
Spring (March–May) and autumn (September–November) are the best seasons. October is often the clearest month.
Monsoon (June–August) makes the trek difficult, with rain and mud. Winter can be very cold, and the lake may partly freeze, so it suits only well-prepared travelers.
Permits and Costs
Permits: You need the Rara National Park entry permit, about NPR 3,000 (roughly $22). Some operators also list a TIMS card. Rara isn’t a restricted area, so a restricted area permit isn’t needed. A licensed guide is still required for trekking in national parks. See our Nepal trekking permits guide.
Costs: The biggest expense is the domestic flights, which one source puts at about $200–$350 round trip. Other operators list full Rara packages from about $1,000 to $2,200, depending on length and service level.
Snowbank’s Rara package starts from about $499. See the Rara Lake package for what’s included.
What to Pack
- Warm layers. Evenings and mornings at the lake are cold.
- Rain jacket and sturdy shoes
- Sun protection and a hat
- Water bottle and purification tablets
- Headlamp and a small first-aid kit
- Cash. There are few places to pay by card.
