There are a handful of giant sequoia trees surviving in Tuolumne Grove in Yosemite National Park. You can reach the sequoias by strolling a mile or so down an old road into the valley. When you first see one of these ancient wonders, it will take your breath away - they are huge across every dimension. In the grove, you'll also find a couple of dead sequoias - one you can walk through and one lying prone, which you can climb on. The hike back up the road is physically demanding, but you will be glad you made the effort.
