The Fern Canyon Trail is a journey into deep time. This 9-kilometer trail leads hikers into a narrow, deeply incised canyon whose sheer walls are so thickly carpeted in ancient ferns that the rock beneath is almost entirely hidden, creating a living tapestry of green that stretches upward for tens of meters on both sides of the trail. Walking through this canyon is an experience unlike any other in the region — the sense of antiquity is palpable, the atmosphere is cool and hushed, and the visual impression is so distinctive that it feels less like a hike and more like a passage through a prehistoric world that has survived into the present against all odds. It is, quite simply, one of the most unique trails you will ever walk.
The ferns that give the canyon its name are not ordinary forest-floor specimens. These are descendants of species that have occupied this canyon for thousands of years, possibly since the last ice age retreated and left behind the cool, moist microclimate that allowed them to flourish. The dominant species include sword fern, lady fern, and the distinctive deer fern, but the canyon also supports several species of maidenhair fern — delicate, black-stemmed plants with fan-shaped fronds that seem far too fragile for the rugged environment they inhabit. The ferns grow from every available crevice in the canyon walls, their roots anchored in thin soil that accumulates on ledges and in fractures, creating a vertical garden of astonishing density and variety. When the wind moves through the canyon, the fronds sway and ripple like a green sea, and the sound they make is a soft, rushing whisper that fills the narrow space with a gentle, ceaseless murmur.
The canyon's geology is equally remarkable. The walls are composed of ancient sedimentary rock laid down in horizontal layers over millions of years, and the canyon itself was carved by a persistent creek that has been slowly cutting through the stone for millennia. The exposed rock faces reveal a geological timeline in miniature, with each layer representing a different epoch and a different set of environmental conditions. Fossils can be found in some of the layers — marine shells and plant impressions from a time when this area was covered by a shallow sea. The combination of living ferns and ancient stone creates a powerful juxtaposition of the living and the geological, the ephemeral and the eternal, that gives the Fern Canyon Trail a philosophical depth rarely found on a hiking route.
The trail begins at the Fern Canyon trailhead, a small parking area situated at the mouth of the canyon where it opens into a broader valley. The path immediately enters the canyon, and the transition is dramatic — within the first 100 meters, the walls rise steeply on both sides and the world outside disappears, replaced by a green-tinged, shadowed corridor that feels utterly removed from the landscape you just left behind. A small creek runs along the canyon floor, and the trail crisscrosses it repeatedly via a series of small wooden footbridges and stepping stones. The crossing points can be slippery when wet, but the water is shallow and the crossings are straightforward in normal conditions.
The first 4 kilometers of the trail follow the canyon floor deeper into the gorge, with the walls gradually increasing in height and the fern coverage becoming denser and more spectacular. The canyon is narrow here — in some sections, barely 10 meters wide — which creates a deeply enclosed, intimate atmosphere where the sky is reduced to a narrow strip of blue far overhead and the light that reaches the floor is soft and diffused. Moss covers every surface that is not occupied by ferns, and the constant moisture from seeps and drips in the canyon walls creates a glistening, jewel-like quality to the rock faces. Water droplets catch the light and sparkle like scattered diamonds before falling to the creek below with a sound like tiny bells. This section of the trail is where the prehistoric atmosphere is most intense, and it is worth pausing frequently to simply look up at the walls and absorb the sheer scale and density of the fern coverage.
At the 4-kilometer mark, the canyon begins to widen and the walls decrease in height. The trail follows the creek through a transitional zone where the canyon opens into a small, flat meadow surrounded by mixed forest. This meadow is a pleasant contrast after the enclosed canyon — open sky, warm sunlight, and a carpet of wildflowers in season. A small wooden shelter and picnic table make this an ideal lunch spot. The return journey follows the same route back through the canyon, and the views are entirely different on the return — the light has shifted, the shadows have moved, and the ferns present a different face to the hiker walking in the opposite direction.
The scenery in Fern Canyon is defined by verticality, greenness, and an almost overwhelming sense of lushness. The fern-covered walls are the primary visual feature, and their impact is immediate and powerful — the density of the growth is staggering, with fronds overlapping and interweaving to create a seamless living surface that extends from the canyon floor to heights of 20 meters or more. The overall color palette is predominantly green, but it is a green of extraordinary variety and subtlety — from the bright yellow-green of new growth to the deep blue-green of mature fronds, with shades of olive, chartreuse, and sage filling in the spectrum. When backlit by sunlight filtering over the canyon rim, the fronds glow translucently, revealing the delicate veining and structural patterns that are invisible in flat light.
The dripping moss and water seeps add another dimension to the scenery. The glistening wet rock faces, the constant slow drip of water, and the small cascades where seeps emerge from the canyon walls create a dynamic, ever-changing visual environment. On cold mornings in late autumn and winter, the water seeps can freeze into delicate ice formations that cling to the rock faces like crystalline sculptures — a stunning contrast to the green ferns that surround them. The narrow strip of sky visible from the canyon floor provides a constantly shifting frame of light and cloud that serves as a natural clock, marking the passage of the day in the changing angle and quality of the illumination.
Trail conditions in the canyon are influenced by the perpetual moisture and limited sunlight. The trail surface is a mix of packed dirt, wooden boardwalks, and rocky sections that can be slippery when wet — which is nearly always. The wooden footbridges across the creek have non-slip surfaces but can still be treacherous in icy conditions. The canyon floor stays damp year-round, and after heavy rainfall, the creek can rise quickly, making some crossings more challenging. Waterproof footwear with good grip is essential. The trail is well-maintained and clearly marked, with boardwalks in the wettest sections to protect both hikers and the fragile creek-bank vegetation. The narrowness of the canyon means that the trail is essentially single-file for much of its length — be prepared to step aside for oncoming hikers. The cool microclimate means that the canyon can be significantly colder than the surrounding area, and the dampness amplifies the chill.
The Fern Canyon trailhead is located approximately 50 minutes from the nearest town. From the highway, turn onto the Fern Canyon Road and follow the paved road for 6 kilometers, then continue on a short gravel section for 2 kilometers to the parking area. The road is suitable for all vehicles. The parking lot is small, accommodating about 15 vehicles, and includes a vault toilet and information board. No permits or fees are required for day hiking. The trailhead is accessible year-round, though the access road may require caution in winter after snowfall. For the best experience, visit on a weekday during the shoulder seasons of spring or autumn, when the canyon is less crowded and the light is at its most dramatic.
