Key Differences

Altitude Comparison

Thamsar Pass sits 700ft above Bagini Glacier at peak altitude. Similar on paper, but the extra elevation accumulates across a full ascent day.

Cost Comparison

Bagini Glacier starts lower at budget tier (₹12,500 – ₹25,000) vs Thamsar Pass (₹24,000 - ₹60,000). The gap at entry level is ₹11,500 — meaningful if you're cost-sensitive.

Better for: Bagini Glacier
