I came down from Sunrise Lakes/HTC through LYV yesterday. Didn't have snowshoes and you certainly don't need them for LYV. If anything, I would bring a yaktrax kind of thing for icy conditions. I had them (never used them) but the trail does get a little icy here and there...mostly in the forested areas where the old snow was packed down on the trail and then turned to ice. If you are looking for a day hike in LYV I would suggest heading up the Muir Trail up towards either Cloud's Rest or east on the high trail above the Merced River past that little lake and the small domes (names??) with the great views up the canyon. Pretty much snow free..like hiking on a cold September day, but lots of deadfall and trail debris from the wind.
I didn't go up LYV to Bunnell Cascade but would expect it being icier down in their...less exposure and lots of tree cover.
Trip report coming later today!
