Best Spring Treks in Nepal (Mar–May): Rhododendron & Climbing Season

Spring brings the hills into bloom and the peaks into reach. Nepal's best March–May treks — when the rhododendron forests flower and the trekking-peak season opens.

Spring is Nepal's other great trekking season — and on the lower and middle hills, the prettiest. From March to May the rhododendron forests erupt in red, pink and white, the days lengthen and warm, and the weather stays stable enough that the trekking-peak climbers come out to play. Slightly hazier than autumn at altitude, but greener and far more colourful below 3,500 m.

If autumn is the season of clear skies, spring is the season of colour. Walk through a hillside of flowering rhododendron at 2,800 metres in April and you'll understand why a lot of guides quietly prefer it.

Best of the spring trails

Annapurna Base Camp

  • Duration: 7–12 days · Max altitude: 4,130 m
  • Spring note: the forest sections through Chhomrong and Bamboo are peak rhododendron in March–April

The lower half of the ABC trail is some of the best rhododendron forest in the country, and the Sanctuary is still snow-fringed and dramatic in spring. A superb first trek. See the ABC trek →

Everest Base Camp

  • Duration: 11–17 days · Max altitude: 5,545 m
  • Spring note: the expedition season — base camp is a tented city and the buzz is real

Trek to EBC in spring and you arrive during the Everest summit season, with the base-camp tent city in full swing. Warmer than autumn down low, with longer days. See the EBC trek →

Langtang Valley

  • Duration: 7 days · Max altitude: 4,984 m (Tserko Ri)
  • Spring note: rhododendron forest on the lower valley; the closest big trek to Kathmandu

No flight to gamble on, a real summit viewpoint, and forest that flowers beautifully in spring. The best-value spring trek near the capital. See the Langtang trek →

Mardi Himal

  • Duration: 4–10 days · Max altitude: 4,500 m
  • Spring note: ridge-line forest in bloom, with Machhapuchhre filling the skyline

A short, scenic ridge trek above Pokhara — low enough to enjoy the spring forest, high enough for a proper Annapurna-and-Fishtail finale. See the Mardi Himal trek →

Spring is climbing season

Pre-monsoon spring is the main window for Nepal's trekking peaks. If you want to go beyond walking, Mera Peak (6,476 m) — Nepal's highest trekking peak — runs in spring and autumn, and is the natural next step for fit trekkers ready to use crampons and a rope for the first time.

Heading out this spring? Pair a lower rhododendron trek with the warming weather and you've got the gentlest introduction to the Himalaya there is — all the routes above are in our catalogue.
