Hidden Waterfalls & Swimming Holes Humboldt County

Tucked between towering redwoods and the rugged Northern California coastline, Humboldt County offers more than just scenic drives and misty forest walks. For those who know where to look, this region is home to a remarkable collection of waterfalls and swimming holes—some well-trodden, others so secret they barely appear on maps. Whether you're chasing the veil of a canyon-side cascade or plunging into an emerald pool beneath an ancient grove, Humboldt's hidden waters offer a kind of wild luxury that's both grounding and unforgettable.

Below is your definitive guide to the region's most enchanting aquatic escapes.

In Prairie Creek Redwoods State Park, just inland from Gold Bluffs Beach, Fern Canyon unfolds like a secret chapter of earth history. Instead of a single waterfall, this canyon boasts a hundred delicate cascades—trickling streams of spring-fed water that shimmer down 50-foot walls carpeted in ancient ferns. The result is an immersive, almost spiritual environment. The short walk into the canyon is straightforward, but the reward is profound: filtered sunlight, birdsong, and the soothing sound of water weaving through the canyon's living walls. It's cinematic—so much so that Jurassic Park: The Lost World was filmed here.

Near the Elk Meadow Day Use Area, Trillium Falls offers a tranquil alternative to the region's more dramatic hikes. The falls themselves are modest in height but beautifully situated—framed by moss-covered boulders and towering redwoods. The 2.6-mile loop trail feels like a retreat into silence, where the only sounds are your footsteps on the soft earth and the gentle cascade of the water. It's an ideal choice for a meditative hike, and a perfect introduction to the quiet elegance of Humboldt's inland forest beauty.

If there's a swimming hole in Humboldt, you'll want to keep to yourself; it's this one. Grizzly Creek Redwoods State Park is elusive, seasonal, and entirely magical. The nearly 400-acre park is not the easiest to traverse, and requires a bit of bushwhacking and local know-how, but that's part of its charm. The payoff is a scenic swimming locale where Grizzly Creek flows into the Van Duzen River. Roughly half a mile downriver is the lesser-known Garrett's Spot swimming hole. Four miles to the west, movie buffs, and specifically, Star Wars fans, will appreciate Grizzly Creek's Cheatham Grove addition—filming location for the iconic forest speeder chase scene in Return of the Jedi.

Inland from the coast, the Mattole River curls through valleys of oak, fir, and maple. At A.W. Way County Park, the river forms wide, sun-dappled pools that invite long swims and quiet picnics. The pace here is slow and blissful—perfect for families, couples, or solo travelers looking to unplug. Grassy areas and shady trees make this an ideal spot to relax with a book or take a post-swim nap. For those staying in the nearby boutique lodges of Petrolia or Honeydew, it's a peaceful day trip into the heart of Humboldt's inland charm.

Where the South Fork Eel River runs parallel with the fabled Avenue of the Giants in Humboldt Redwoods State Park, you'll find a string of swimming holes that feel plucked from another era. At spots like Hidden Springs and Robinson Grove, Gould River Bar, Women's Federation Grove, and Dyerville Bar, the river moves with a glassy grace, shaded by redwoods that stretch a hundred feet high. Each bend in the river reveals something slightly different, and Humboldt is at its most iconic: timeless, unhurried, and quietly magnificent.

Just off Highway 36, Swimmer's Delight and nearby Pamplin Grove in Van Duzen County Park represent the best of Humboldt's summer rhythm. The Van Duzen River carves graceful arcs through sandstone banks, forming inviting pools where families gather, couples linger, and adventurers plunge from river rocks. The water is brisk but not biting, and the golden light that filters through the canopy makes everything feel just a little more cinematic. Nearby parks offer basic amenities, but the vibe is always wild and relaxed—like the very best summer camp for grown-ups.

Late spring through early autumn is the ideal window for exploring Humboldt's natural waters. Waterfalls like Trillium are best seen after winter rains, while swimming holes along the Eel and Van Duzen Rivers become especially inviting by midsummer.

While some sites, such as Van Duzen County Park, offer restrooms, parking, and picnic areas, many of Humboldt's most magical spots are minimally developed. Gravel roads, narrow trails, and cool river currents are part of the experience. Swim safely, travel with awareness, and if you're venturing off the grid, consider hiring a local guide to enhance both safety and storytelling.

Exploring Humboldt County's natural treasures is an immersive experience. Whether you're admiring the range of wildlife from a local or state park, swimming in riverbeds beneath hidden waterfalls, or hiking the region's diverse landscape, the best moments in Humboldt County are most often spent outdoors.

While the natural aesthetics are second to none, the real estate in this majestic stretch of Northern California is equally impressive.
