The Hidden Gem of the Hamakua Coast
Nestled along the scenic Hamakua Coast of the Big Island, Kolekole Gulch Park is what many locals call a “jungle gem.” It’s a place where the tropical lushness of Hawaii is on full display, and the journey of the water that tumbles down the famous Akaka Falls finally meets its end at the Pacific Ocean.
When you first pull off the highway, the contrast is striking. Below you lies a tranquil, palm-fringed stream and a verdant gorge, while towering 100 feet overhead is the massive steel highway bridge that spans the gulch. It’s a unique blend of industrial history and raw natural beauty. But there is a secret to this location: while the park offers a lovely view of the lower cascades, the true crown jewel—the massive 250-foot Kolekole Falls—is tucked away upstream on private land, requiring a bit more than a standard parking permit to witness.
Kolekole Gulch Park: What to Know Before You Go
If you’re planning a DIY visit to the park, timing and directions are key.
Location & Access: You’ll find Kolekole Gulch Park just north of Hilo. Take Highway 19 (the Mamalahoa Highway) and look for the turnoff near mile marker 14. The access road turns sharply and winds down into the gulch, surrounded by vibrant ferns and tropical flowers.
Facilities: Despite its rugged appearance, the park is well-equipped for a day trip. You’ll find:
- Picnic pavilions and tables for family gatherings.
- Restrooms and outdoor showers to rinse off after a dip in the stream.
- Grassy areas perfect for lawn games or simply relaxing in the shade of a Koa tree.
Parking Tips: The parking lot is paved but relatively small. Because this is a favorite spot for local families, it can fill up incredibly fast on weekends and holidays. If you want a peaceful experience, aim for a weekday morning.
Renovation Update: Visitors should note that the park underwent significant renovations in 2024 and 2025. These updates were designed to improve accessibility and enhance the facilities, ensuring that the park remains a safe and enjoyable resource for the community.
Top Activities at Kolekole Gulch
Kolekole is not your typical white-sand beach destination; it’s an adventure in a tropical gorge.
Swimming & Stream Play: While the ocean here is often too rough for a swim, the freshwater Kolekole Stream acts as a natural swimming pool. The water is cool, refreshing, and far calmer than the pounding surf just a few yards away.
The Lower Falls: Right within the park grounds, you can enjoy the view of a picturesque, multi-tier waterfall. It’s the perfect backdrop for photos and provides that iconic Hawaii atmosphere without requiring a long hike.
Picnicking & “Talk Story”: In local culture, “Kolekole” can mean “talk story” or chat with friends. You’ll often see groups of locals barbecuing and sharing stories under the pavilions. Embracing this slow-paced, community-focused vibe is the best way to enjoy the park.
Safety First: Ocean Hazards & Environmental Notices
While the park is beautiful, Mother Nature demands respect here.
Ocean Warning: We strongly advise against ocean swimming at Kolekole. The shore is rocky, the currents are notoriously treacherous, and the river mouth is a known area for shark activity due to the murky water. Stick to the stream for your water fix.
Water Safety: Like many freshwater sources in Hawaii, Kolekole Stream can carry leptospirosis. Avoid swimming if you have open cuts or scratches, and never drink the stream water.
Lead Contamination Update: An important note for current travelers: some areas near the bridge supports remain fenced off. This is due to historical lead paint from the old bridge structure that contaminated the soil. Respect all posted signs and stay within the designated safe zones.
The Ultimate View: Ziplining Over Kolekole Falls
If you really want to see the scale of the Hamakua Coast’s waterfalls, you have to look up. The 250-foot upper Kolekole Falls is located on private property and cannot be reached through the public park.
The only way to witness this giant is through a Hawaii Zipline & Hiking Tour. Our course features a grand finale that is truly unmatched: a half-mile-long line that soars over a 450-foot ravine, placing you directly above the mesmerizing Kolekole Falls. It is the only zipline in Hawaii that flies you over a waterfall of this magnitude. From this vantage point, you can see the sheer power of the water as it plunges toward the gulch below—a view you simply can’t get from the ground.
Planning Your Adventure: Zipline vs. Park Visit
Why choose when you can do both? Many visitors find that a “combo” day is the best way to experience the Hilo side.
Combo Trip: Start your morning with the thrill of our Kolekole Waterfall Zipline Adventure. You’ll get exclusive access to the upper falls and learn about the local flora and fauna from our expert guides. Afterward, head down the road to Kolekole Gulch Park for a picnic lunch and a relaxing dip in the lower stream to cool off.
What to Pack:
- Closed-toe shoes: These are a strict requirement for ziplining and helpful for navigating the rocky terrain at the park.
- Reef-safe sunscreen: Protect your skin and the local ecosystem.
- Towels & Swimwear: You’ll definitely want these for the stream.
- Rain Jacket: The Hilo side is lush for a reason—passing showers are common!
