I am new to hiking, can anyone tell me if this is a lot more challenging than Mt Rose or if it’s a similar hike? I was able to do Mt Rose in ~6 hours, struggled a bit near the top but did okay overall.

The trail is quite uneven/rocky almost the whole way, which makes it more challenging. Haven't done Mt Rose so can't compare. Check out comments on AllTrails

This is a "get up at 7am, get there by 8am or 9am and hike till 2pm or 3pm" kind of hike. The path starts tame and then gets rockier as you climb. If you're a fast hiker it doesn't matter, watch where you step, seriously, the climb can get intense.
