The altitude gap here is significant. Brahmatal takes you 3,250ft higher than Thamri Kund Lake — expect meaningfully harder breathing, a slower pace on the upper section, and a real difference in AMS risk between the two.

Both require prior experience, but Brahmatal scores 23 difficulty points higher. If you're building progressively, Thamri Kund Lake is the better starting point.

Thamri Kund Lake starts lower at budget tier (₹500 - ₹1,500 (Day hike)) vs Brahmatal (₹7,500 – ₹12,000). The gap at entry level is ₹7,000 — meaningful if you're cost-sensitive.
