Key Differences

Altitude Comparison

Kalihani Pass takes you 1,300ft higher than Chandranahan Lake. That extra altitude is real — expect a slower pace and more deliberate hydration above camp.

Cost Comparison

Chandranahan Lake starts lower at budget tier (₹7,000 – ₹13,000) vs Kalihani Pass (₹15,000 to ₹22,000). The gap at entry level is ₹8,000 — meaningful if you're cost-sensitive.
