I believe this is the easiest place to see the most giant sequoia trees in one area. The paved trail, about a mile long loop, is easy to walk, and it puts you right next to some of the largest trees on earth. Grant Grove is also the closest part of of the park from Fresno, so it only takes about an hour to drive here from the city. It is usually accessible in winter, but you should still check beforehand.
