21 Underrated National Parks for Avoiding Summer Crowds

21. Redwood National and State Parks (California): Finding Peace Among Giants

While specific hubs like the Lady Bird Johnson Grove Trail can get busy, the sheer size of this combined park complex along California's northern coast allows ample opportunity to escape summer crowds. Hike deeper into less-famous groves on trails like Tall Trees Grove (permit needed, limits numbers) or explore the rugged coastline sections like Enderts Beach Trail. Coastal fog often provides natural air conditioning, offering a cool respite from inland summer heat while you wander among the world's tallest trees in relative solitude.
