Head into the national park this morning, and join your leader for an easy, downhill hike at the Tuolumne Grove of Giant Sequoias. The grove is home to, no surprise, a couple dozen mature giant sequoia trees, including one that’s been carved into a tunnel you can walk right through. From there, continue to Yosemite Valley to check out some of the park’s iconic spots. You could see the thundering Yosemite Falls, take in both Half Dome and Merced River from Sentinal Bridge and a whole lot more. The rest of the day is then free for you to explore as you please. There are plenty of hikes available, each varying in steepness and difficulty. Maybe hike under the cooling breezes of Nevada Falls (4 to 5 hours) or to the serene Mirror Lake (45 minutes). Keep an eye out for squirrels and bears along the way!
