20 Best National Parks in the U.S.

"Renowned for its towering giant sequoias and numerous groves, this park contains some of the world’s largest living trees and dramatic natural features. The Giant Forest holds the ancient Sherman Tree—the largest living tree by volume—and visitors also explore sites such as Hospital Rock, Crescent Meadow, and Moro Rock; recent large fires affected several groves but many sequoias survived." - Lydia Mansel Lydia Mansel Lydia Mansel is a writer with more than eight years of experience editing and writing for both brands and online publications—with a particular focus on travel, fashion, and lifestyle.
