You're not comparing two treks.

We can show you the numbers, but we'd be doing you a disservice if we didn't say this first: Bagini Glacier Trek and Bijli Mahadev Trek are not alternatives — they are different sports. One is a 8-day experience reaching 16,400ft, the other is 1 days reaching 8,000ft. If you're choosing between these two, one of them likely isn't an option for you yet.
