Best time to visit west Nepal: Rara, Khaptad and the Karnali roads by month

West Nepal has no single best month, because the answer depends on whether the plan is a flight to Talcha, a bus up the Karnali Highway or a trek to Khaptad. Sources give different month ranges for the same lake. This page sets them side by side, with the Nepal Tourism Board’s figure as the baseline. The road side of the question is in monsoon road closures, and the other planning pages are in the getting there hub.

The seasons

Nepal has five seasons: spring, summer, monsoon, autumn and winter². Spring runs March to May, the monsoon June to August, autumn September to November and winter December to February in one operator’s calendar⁴. As in most trekking areas of Nepal, the best time to visit is spring and autumn, per the Nepal Tourism Board climate page². Spring is when the rhododendrons bloom, and the clearest skies come after the monsoon in October and November².

Altitude matters in the far west. Average temperatures in Nepal drop 6 degrees C for every 1,000 m gained², and in mountainous regions winter temperatures can fall below zero². Rara National Park ranges from 2,800 to 4,039 m, with the lake at 2,990 m⁷.

Rara: what each source says

The Nepal Tourism Board’s Rara National Park page is the government source and the baseline here; operator and press ranges follow it.

October is the one month inside all five ranges^1,4,5,6,8. The Nepal Tourism Board’s climate page says December and January, when winter is at its severest, bring bright sun and brilliant views².

Monsoon: June to September

Eighty percent of all the rain in Nepal falls during the monsoon, June to September². The monsoon makes the trek to Khaptad and Rara difficult⁶, and the climate note for Rara National Park gives June to August as monsoon season, making the trek difficult⁷.

The roads show it. In a report of 17 August 2025 landslides blocked the Karnali Highway at Gaganekhola and Bihani in Kalikot, at Khidki Jyula in Dailekh and near Nagma on the road to Mugu⁹. In July 2026 the highway was completely blocked from 7 pm on a Saturday after a landslide at Gagane Khola, during the peak season for transporting apples from Jumla, Mugu and Humla¹⁰. The full record is in monsoon road closures.

Weather in Nepal

Northern Nepal has cool summers and severe winters, while the south has very hot summers and mild to cold winters². In the Tarai, summer temperatures exceed 40 degrees C, and above 45 in some areas, and winter temperatures range from 7 to 23 degrees C².

Kathmandu Valley

The valley has average summer temperatures of 20-35 degrees C and 2-12 degrees C in winter². The Nepal Tourism Board climate page also gives the national baseline: temperatures drop 6 degrees C for every 1,000 m gained², and Rara Lake lies at 2,990 m⁷.

Winter: December to March

At Rara Lake the temperatures from December to March are below freezing, and heavy snowfall blocks the way to the lake³. From December to February both national parks are covered with snow and the trails are not accessible⁶. The climb can also be harder in winter because of the temperature, according to one operator⁴.

Winter has its own pull: 214 species of birds are seen at Rara in winter¹. The Kathmandu Post reported in February 2018 that Rara’s winter visitors depend on snow, and that without snowfall that winter the lake did not attract them⁸. Winter rains are more pronounced in the western hills².

Khaptad

Khaptad National Park was established in 1984, covers 225 km2 across Bajhang, Bajura, Achham and Doti, and ranges in elevation from 1,400 to 3,300 m¹¹. The seasonal guidance that covers it is an operator’s: mid-September to December and March to May for Khaptad and Rara⁶. The same page puts Shuklaphanta National Park at September to mid-December and February to the end of May⁶.

Entry fee: two Board pages

The Board’s Rara page lists entry at NPR 25 per person per entry for Nepalis, NPR 1,500 for SAARC nationals and NPR 3,000 for foreigners¹. The Board’s park entry-fee table, seen in October 2026, lists NPR 100 for Nepalis with the same NPR 1,500 and NPR 3,000¹². The two government pages disagree on the Nepali amount. Fees for the other parks are on national park fees.

Getting there in season

The Board’s access line for Rara is a flight from Nepalgunj to Talcha Airport, 35 minutes, then a 2-hour trek to the lake, or a 2.5-day trek via Jumla¹. Timings for the road legs are in buses and jeeps and Kathmandu to the far west by road.
