Lachen in May
Sikkim, India
Go in May—Gurudongmar is fully accessible and weather is stable, but arrive early to beat jeep traffic and expect inflated lodge rates.
Peak crowds
May is one of Lachen's busiest months. The score rates conditions — weather, access, value — not how many people you'll share them with. North Sikkim gateway peaks in spring (Mar–May) and autumn (Oct–Nov) when roads open and weather is mild; summer monsoon and winter snow make it inaccessible.
May Lachen is a staging ground buzzing with jeeps headed to 5425m. The village itself is warm, green, and easy to love.
The May story
Everyone treats Lachen as a pit stop. Stay an extra day — the Chopta Valley walk and monastery visits are worth your time.
