The Old Growth Loop Trail offers a delightful, easy hike through a unique section of ancient redwood forest in Nisene Marks State Park. You'll wander among trees over a thousand years old, traverse a charming Wooden Bridge Over Aptos Creek, and discover the intriguing "Twisted Grove" where redwoods grow in unusual, gnarled shapes. This 0.8-mile (1.3 km) loop gains just 137 feet (42 metres) and takes about 22 minutes, making it an ideal, family-friendly option for a quick immersion into nature.
When planning your visit, be aware that the Wooden Bridge Over Aptos Creek is seasonal, typically installed from May through October. Outside these months, crossing the creek can be challenging or unsafe, especially after rain. Dogs are welcome on a leash, and the trail's accessibility makes it a great choice for a relaxed outing any time of day during the bridge's operational season.
While some might compare it to other, more expansive redwood groves, the Old Growth Loop Trail holds its own with distinct features like the "Twisted Grove," possibly shaped by seismic activity. It provides a serene atmosphere along Aptos Creek, showcasing a rich riparian plant community with big-leaf maples and ferns alongside the towering redwoods. It's a fantastic way to experience the majesty of old-growth trees without committing to a longer, more strenuous adventure.
