Founders Grove - Avenue of the Giants, California

When visiting Northern California, be sure to drive along the Avenue of the Giants. Make note of Founders Grove, an old-growth grove where 2,500-year-old trees tower over you at ridiculous heights. The fallen trees are just as amazing. Everything is so gigantic you'll feel like a tiny ant, running around taking photos. It gets dark in the late afternoon in the fall, so use a flash. Good luck.
