Thorong La Pass: 15 Tips for Safe Crossing

Thorong La (5,416m) separates the Manang valley from Muktinath on the Annapurna Circuit. Every year, trekkers underestimate it — this checklist exists to prevent that.

Overview

The crossing from High Camp (4,925m) to Muktinath (3,760m) covers 16km with a 490m ascent and 1,650m descent in one long day. Start time is critical: depart High Camp no later than 5:00am. Afternoon winds make the pass dangerous and visibility can drop rapidly. The descent to Muktinath is long on the knees — trekking poles are essential. Book a Sajilo cab to Kathmandu bus park before your trek to ensure you reach the Besisahar bus on time.

FAQ

What altitude is High Camp? High Camp sits at 4,925m — spend at least two nights in Manang (3,519m) and one at High Camp before crossing.

What happens if weather closes the pass? The pass closes with heavy snowfall (usually December-February). Always check conditions at High Camp the evening before. Groups have been stranded for days.

Can I cross without a guide? Legally yes, but the upper section in poor visibility is a whiteout risk. Many solo trekkers team up informally with others at High Camp.
