9) Sequoia & Kings Canyon National Park
Sequoia and Kings Canyon Parks are very close to one another and home to the largest trees in the world. There are several groves with the largest being Giant Forest in Sequoia National Park. The General Sherman Tree, the largest tree in the world based on volume, is located here. It is 275 feet tall and 36 feet in diameter at the base. To photograph an entire tree, head to Grant Grove in Kings Canyon, where there is a vantage point that makes it possible to capture the General Grant Tree in one frame. Every year a wreath is placed on the tree in honor of it being the National Christmas Tree. Visitors can hike, camp or rent lodgings, but should be aware of black bears in the area. Proper food storage is essential to safety. Vehicle passes are $30 and good for a week. Individuals on foot or bicycle can enter for $15.
