Here are two of my favorite hikes to add to your cal when venturing into Sequoia and Kings Canyon National Parks, in California:
Trail of the Sequoias
Immerse yourself in the Redwood forest. You'll discover streams, moss, and serenity.
This hike starts at the General Sherman Tree- the largest tree in the world (by volume). You'll eventually discover Tharp's log and beautiful meadows. If you hike the trail in it's entirety expect to be on your feet for 3+ hours.
