Headwaters Forest Reserve: Protected Redwoods and Old-Growth Sanctuary
Near Eureka in Humboldt County (BLM-managed), Headwaters Forest Reserve safeguards 7,472 acres of protected old-growth coast redwoods, including the Headwaters Grove with some of the tallest trees on Earth. This reserve; established after a landmark preservation effort; offers guided tours and quiet trails through pristine forest.
A Protected Old-Growth and Riparian Mosaic
Headwaters blends ancient coast redwoods (some 300+ feet tall, 2,000+ years old), fern understory, and Elk River riparian zones. Banana slugs, varied birds, black bears, and seasonal rhododendrons thrive; the reserve exemplifies recovered old-growth habitat after decades of protection.
Adventure With a Conservation Conscience
Guided tours (seasonal, free, reservations via BLM) to Headwaters Grove; self-guided South Fork Elk River Trail (moderate, 5 to 10 miles) through redwoods.
Access is intentional: free parking at trailheads, sunrise to sunset, pack out waste, stay on trails. Guided tours required for inner groves; no pets; check BLM for tour availability.
Headwaters Forest Reserve delivers protected redwoods hiking in ancient splendor. For those seeking tallest giants and ferny shade, the trails reward guided or careful access; a preserved redwood legacy.
