Day walks in Yosemite

Hi everyone,
I'll be near Yosemite Nat Pk at the end of May.
Was going to climb Half Dome, unfortunately unsuccessful in the lottery draw.
So now, my plane ticket is booked, hotel is booked, but no walk
Can you suggest a day walk (long day walk is fine, but no overnights) in or around Yosemite?
And do I have to worry about bears in whatever walk you are going to suggest?
Cheers, Paul
