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: Jalori Pass & Serolsar Lake Trek and Vasuki Tal Trek - Kedarnath are not alternatives — they are different sports. One is a 1-day experience reaching 10,280ft, the other is 5 days reaching 11,750ft. If you're choosing between these two, one of them likely isn't an option for you yet.
