Rhododendron season in Nepal, where and when

Rhododendrons turn the middle hills of Nepal red, pink and white in spring, and the timing is easy to remember: bloom begins low down in March, peaks in April on the southern slopes of Annapurna, below Namche in the Everest region and up the valleys of Makalu and Kanchenjunga, and is still good in May, though warmer and hazier. The Nepal national flower, Rhododendron arboreum, produces trusses of red, pink or white flowers in early and mid spring, according to Wikipedia, and the forests it grows in are on many classic trails.

This guide says where to look, when, and what to trade off against crowds, using our region and route pages, checked on 19 October 2026. It does not promise a bloom on a given date: flowering shifts from year to year with the weather, so build slack into your plan and treat the dates as windows. For the full spring picture, see trekking in Nepal in March, April and May.

The pattern across the season

Our region pages describe the same sequence in several places:

• March. Rhododendron begins to flower in the lower forest, as our Annapurna, Everest, Langtang, Makalu, Manaslu and Rolwaling pages say. Higher up, snow may linger and the passes may still hold deep snow.
• April. The spring peak. Our Annapurna page says rhododendrons flower on the southern slopes at Ghorepani and Ghandruk with mostly clear skies, our Everest page says they flower below Namche, and the Makalu and Kanchenjunga pages add magnolia in bloom.
• May. Warmer and hazier, with afternoon cloud, but a good window before the monsoon. Leeches begin to appear in the lower forest late in the month in Makalu and Rolwaling.

Bloom starts low and moves up as spring warms the slopes, which is why a walk that climbs from 2,000 m to 3,000 m can pass flowers at different stages. The exact timing at a given altitude is not something our sources predict.

Where to see them

The forest between Ulleri and Ghorepani is the easiest to reach: a four-day walk from Pokhara with a top of 3,210 m at Poon Hill. Our Poon Hill route page describes the Ghorepani climb as through oak and rhododendron forest, and says that in spring the flowers colour the forest. The Annapurna Base Camp walk passes rhododendron and bamboo forest between Sinuwa and Deurali on days 2 and 3. If you want flowers with big mountain views in a short trek, these two are the standard choices, and our Poon Hill itinerary and Annapurna Base Camp itinerary walk through them.

Everest, Makalu and Kanchenjunga

In the Khumbu, the best flowers are below Namche on the way up from Lukla. Our Everest page calls April the spring peak, with rhododendrons flowering below Namche, expedition teams at Base Camp and lodges filling from mid-month. The plan flies Kathmandu to Lukla on day 1 and goes through Phakding and Namche; see the Everest Base Camp cost breakdown for what that costs and the Lukla flight guide for the logistics.

Makalu and Kanchenjunga are the wilder options. Our Makalu page says April is the spring peak with rhododendron and magnolia in bloom, clearer mornings and stable snow, and the route highlights describe forest that changes from rhododendron to birch and juniper within a few days. Both are remote, hard treks with restricted-area or park permits and a guide, so they suit experienced trekkers; read the Makalu Base Camp itinerary and our Kanchenjunga region guide before committing.

Short walks and day hikes

You do not need a long trek to see the flowers. Our Kathmandu Valley page says March and April bring rhododendron flowers to the upper slopes of the Shivapuri trails, and the Pokhara page says the Panchase ridge has flowers in March and April. The Kathmandu Valley rim hikes guide, short treks from Kathmandu and short treks from Pokhara list options. Our Panchase trek guide covers the ridge.

Planning around crowds and weather

April is the busiest month, so book flights and lodges early, especially on the Everest route, where our page says lodges fill from mid-April. March has fewer people and early flowers but cold nights and possible snow on the high sections; May is quieter but warmer, hazier and sometimes cloudy in the afternoon. The monsoon follows, so May is the last good window on most routes; our April and May guides compare them.

Photograph in the morning, when our pages say skies are clearest and the light is soft. On a flat horizon Kathmandu has about 12.8 hours of daylight in mid-April, with sunrise near 05:40, by our calculation, so a dawn start is early. Walk on the trail, do not pick flowers or branches, and ask before photographing people.

Permits, costs and the guide rule

Permits do not depend on the bloom. As of October 2026 the Annapurna Conservation Area permit is NPR 3,000 for foreigners, with online payment adding a 2.9% gateway charge and a permit issued at a check post costing double; the Sagarmatha National Park permit and the Khumbu trek card are NPR 3,000 each; and the Makalu Barun National Park permit is NPR 3,000. Restricted-area permits for Manaslu, Tsum Valley and Nar Phu are priced at the lower December to August rate in March, April and May. The daily budget guide shows how to budget, and the permits page keeps the current table.

The Nepal Tourism Board announced in April 2023 that foreign trekkers must use a licensed guide in national parks and conservation areas. We found no separate Department of Immigration or park-authority notice, and 2026 operator reports say checkpoints enforce it in Annapurna and Langtang, the strictest, and most other parks, but not in Khumbu (checked 19 October 2026). In restricted areas a licensed guide through a registered agency is part of the permit. See the guide rule explainer.

Common mistakes

A few errors recur. People book the peak week of April and find the lodges full, when March or May would have given them flowers and space. They expect the bloom to match a date, when it shifts with the weather of each spring. They climb for the flowers and forget that the forest is also home to leeches from late May and to cold mornings in March. And they treat the flowers as the whole trip, when the same days include steep stone steps, long climbs and weather that can change by afternoon. Plan for the walk first and the flowers as a bonus, keep a day or two of slack, and the bloom will usually repay you.

A sample plan

1. Choose by time. Four days: Poon Hill. Seven days: Annapurna Base Camp. Two weeks or more and strong legs: Makalu in April.
2. Pick the week. Aim for the first three weeks of April for the peak, with March for fewer people and early flowers.
3. Keep spare days. Flights and snow can move your plan, and bloom can run early or late.
4. Pack for both seasons. Spring mornings are cold and afternoons are warm; see the packing list.
