Oahu’s waterfalls offer a refreshing escape from the island’s famous beaches. This guide unveils some less-traveled waterfall hikes, complete with directions, insider tips, and essential information to make your adventure safe and memorable. Get ready to discover Oahu’s hidden natural beauty!
Understanding Waterfall Safety on Oahu
Before we dive into the specific hikes, let’s talk safety. Oahu’s waterfalls are beautiful, but they can also be dangerous. Flash floods are a real threat, especially after heavy rain. The rocks are often slippery, and leptospirosis, a bacterial disease, can be present in freshwater streams. Always check the weather forecast before you go, and avoid hiking near waterfalls after heavy rainfall. Wear appropriate footwear with good traction, and consider water shoes or hiking sandals that can get wet. Cover any cuts or scrapes to minimize the risk of leptospirosis. If the water looks murky or smells bad, stay out of it. Your safety is paramount, so err on the side of caution!
Manoa Falls Trail
This is perhaps Oahu’s most famous “secret” waterfall, meaning it’s quite popular but still feels secluded amidst lush rainforest. Manoa Falls plummets 150 feet, creating a dramatic backdrop. The trail is relatively easy, but it can be muddy and slippery, especially after rain. The hike is about 1.6 miles roundtrip and takes about 1-2 hours to complete. Parking can be tricky; there’s a paid parking lot near the trailhead (expect to pay around $5). You might also find street parking further down Manoa Road, but be respectful of residents and be prepared for a bit of a walk. Insect repellent is a must here as mosquitos are prevalent.
Getting There: From Waikiki, take H-1 West and exit onto Punahou Street. Follow Punahou Street until it becomes Manoa Road. Continue on Manoa Road until you reach the end, where you’ll find the Manoa Falls Trail entrance.
Insider Tip: Go early in the morning to avoid the crowds and the midday heat. The light is also often better for photography in the morning.
Aihualama Falls (Judd Trail)
Aihualama Falls, accessed via the Judd Trail, offers a less crowded alternative to Manoa Falls. This is a loop trail, roughly 2 miles in length. The initial portion traverses a pine forest before descending into a lush valley. The waterfall itself isn’t as towering as Manoa Falls, but the overall experience is more immersive and peaceful. The trail can be muddy, particularly after rain, so sturdy shoes are recommended. The stream crossings are usually shallow, but be prepared to get your feet wet. Swimming at Aihualama Falls is possible in the pool at its base and many consider it the main draw of this trail.
Getting There: From Honolulu, take the Pali Highway (Route 61) toward Kailua. Turn left onto Nuuanu Pali Drive. Follow Nuuanu Pali Drive for about 1.5 miles. The Judd Trailhead will be on your right. There’s a small parking area near the trailhead.
Insider Tip: The pine section of the trail can be hot as there’s less shade. Consider bringing extra water and wearing a hat. Watch out for guava, you can eat it, but it often litters makes the rocks slippery.
Lulumahu Falls
This is where things get a little more adventurous. Lulumahu Falls is a stunning multi-tiered waterfall hidden deep in the Ko’olau Mountains. To get to the falls, you’ll need to hike through a bamboo forest and navigate a stream, which can be quite challenging. This hike requires a permit. You can obtain a permit online through the Division of Forestry and Wildlife’s website for a small fee (currently $2.50 per person). No permit, no hike; they check regularly and the fine is substantial. The trail is roughly 2 miles roundtrip, but the terrain is uneven and slippery. Wear good hiking shoes that can handle water, and be prepared to get wet and muddy. The hike is moderately challenging and takes about 2-3 hours.
Getting There: From Honolulu, take the Pali Highway (Route 61) toward Kailua. Turn right onto Nuuanu Pali Drive. Drive a short distance to the entrance of the Nuuanu Pali State Wayside. Park outside and walk along the concrete barrier (do not hop the fence). After crossing the water catchment area, the dirt trailhead starts on the left.
Insider Tip: Bring a dry bag to protect your electronics and valuables. Check water levels before going. Leptospirosis is a risk, so cover any wounds and avoid drinking the water. Make sure you have your permit readily available.
Likeke Falls
Likeke Falls is a lesser-known waterfall located near the Ko’olau Golf Club. This is a short, but potentially muddy hike, roughly one mile roundtrip. The waterfall is about 20 feet high, cascading into a small pool. The path is moderately easy to follow but it has a steady incline. The trailhead might be hard to find at first, and parking can be limited. Unlike Lulumahu Falls, a permit is not generally required to hike to Likeke Falls.
Getting There: Take the Likelike Highway (Route 63) towards Kaneohe. Just before the Wilson Tunnel, take the last exit on the right before the tunnel. This will lead you past the Veterans Cemetery. Follow this road as it curves around the back of the Ko’olau Golf Club. Continue until you see a small parking area on the right, beside a metal fence. The trailhead is just beyond the fence.
Insider Tip: Exercise caution, as this area is prone to flash flooding. Mosquito repellent is essential due to the dense vegetation. Respect the surroundings and pack out any trash.
Maunawili Falls Trail
Maunawili Falls is a popular, yet challenging, hike located on the windward side of Oahu. This is a 3-mile roundtrip hike leads to a 20-foot waterfall perfect for a refreshing swim. The trail can be muddy and slippery, with several stream crossings. Parts of the route can be fairly challenging, with steep inclines and declines. The trail itself has multiple entry points and some can be easier than others to tackle. While the waterfall and pool are popular for swimming, be aware that the water quality can vary and leptospirosis is a potential risk, as it is elsewhere on Oahu. There is parking along the road at the trailheads. In years prior the Maunawili Falls hike was shut down due to the trails unsafe conditions, but has since been restored by the State of Hawaii.
One trailhead can be difficult to find, especially as it begins as an extremely narrow chute. For this trailhead, walk along Maunawili Road away from town from 10-15 minutes. As the road begins to slope upward you will see a number of cars parked a little off the road. Across the street from this lineup of cars, behind a metal guardrail, there is a narrow and dark opening in the forest. This marks what is one of the most challenging trailheads.
Getting There: From Honolulu, take the Pali Highway (Route 61) toward Kailua. Exit onto Auloa Road. Take a right onto Maunawili Road. Continue for a few miles. There will be several places to park along the road. The key is seeing a break in the right guardrail and then finding that small chute trailhead entrance across the street.
Insider Tip: Wear sturdy hiking shoes and be prepared for mud. Bring plenty of water and insect repellent. Exercise caution when crossing streams. The depth can vary based on recent rainfall. As the trail crosses private lands, be sure to stay on the marked trail. Jumping off the falls is dangerous and not recommended. Watch for falling rocks along the trail.
Hamama Falls
Hamama Falls is another option for a lesser-known waterfall experience. Reaching Hamama Falls typically involves a longer and moderately strenuous hike, often incorporating stream crossings and navigating uneven terrain. The most common route is about 4 miles roundtrip. The falls themselves are rewarding, cascading down a rock face into a serene pool. This adventure requires more planning compared to other hikes, mainly because it’s not always clearly marked and involves some route-finding skills. The reward is often a much more solitary waterfall experience. You can bring your dogs on this one too!
Getting There: From Honolulu, drive north on the H-3 Freeway. Take the Kaneohe exit toward Kamehameha Highway (Route 83). Drive north, passing through Kaneohe. Look for a turnout parking area about a mile past the Valley of the Temples. On your right will be a wide opening to the Hamama Stream.
Insider Tip: Be prepared to get wet, and wear appropriate footwear. Check the water levels before you go. Since the trail isn’t as well-maintained, watch out for potential hazards along the path, like loose rocks, branches, and slippery sections. It’s recommended to go with a friend, and let someone know you are going, as phone service in the valley can be limited.
Essential Gear for Waterfall Hikes
Regardless of which waterfall hike you choose, you’ll want to be properly prepared. Here’s a checklist of essential gear:
- Hiking Shoes: Sturdy shoes with good traction are crucial, even for the easier hikes. Consider water shoes or hiking sandals that can get wet.
- Water: Bring plenty of water to stay hydrated, especially on longer hikes.
- Snacks: Pack some energy bars, fruit, or other snacks to keep your energy levels up.
- Insect Repellent: Mosquitoes and other insects can be a nuisance, especially in the rainforest.
- Sunscreen: Protect your skin from the sun, even on cloudy days.
- Rain Gear: A light rain jacket or poncho can be helpful, as rain showers are common in the mountains.
- First-Aid Kit: A small first-aid kit with band-aids, antiseptic wipes, and pain relievers is always a good idea.
- Dry Bag: To protect your valuables (phone, camera, wallet) from water damage.
- Towel: If you plan on swimming, bring a quick-drying towel.
- Permit (if required): For hikes like Lulumahu Falls, don’t forget to obtain a permit beforehand.
Respecting the Environment
Remember to leave no trace behind. Pack out all your trash, and avoid disturbing the vegetation or wildlife. Stay on the marked trails, and be respectful of other hikers. Many of these areas are sacred to Native Hawaiians, so treat them with reverence. By following these simple guidelines, you can help preserve Oahu’s natural beauty for future generations.
Finding the Trailheads
One of the biggest challenges of hiking to Oahu’s secret waterfalls is finding the trailheads. Many are unmarked or poorly marked, and some are hidden away in unexpected locations. Use GPS coordinates, offline maps, and detailed directions. Online hiking forums and blogs can also be valuable resources. Be patient and persistent, and don’t be afraid to ask for help from locals. Once you find the trailhead, the adventure begins!
Alternative Activities near Waterfalls
Consider combining your waterfall hike with other activities in the area. For example, after hiking to Manoa Falls, you could visit the Lyon Arboretum, a beautiful botanical garden located nearby. After hiking to Maunawili Falls, you could explore the charming town of Kailua or relax on Kailua Beach. Look into local attractions, like the Byodo-In Temple, the Ho’omaluhia Botanical Garden, or various historical heritage sights. All of these will likely be accessible while following specific highway routes and offer a diverse experience of Oahu’s natural and cultural offerings.
Seasonal Changes in Waterfall Flow
The flow of Oahu’s waterfalls varies throughout the year, depending on the rainfall. During the winter months (November to March), when rainfall is heavier, the waterfalls are typically at their fullest and most impressive. During the summer months (April to October), when rainfall is lighter, the waterfalls may be smaller or even dry up completely. Before planning your hike, check the recent rainfall patterns to get an idea of what to expect. Don’t be discouraged if the waterfall isn’t as spectacular as you imagined; the hike itself is often a rewarding experience.
Photography Tips
Waterfalls make for stunning photographs, but capturing their beauty can be challenging. Here are a few tips:
- Use a tripod: A tripod will allow you to use slower shutter speeds, which will blur the water and create a silky smooth effect.
- Shoot in manual mode: Manual mode gives you full control over your camera’s settings, allowing you to fine-tune your exposure.
- Use a polarizer: A polarizer filter will reduce glare and reflections, making the colors more vibrant.
- Shoot on cloudy days: Overcast skies provide soft, even lighting, which is ideal for photographing waterfalls.
- Protect your gear: Use a waterproof bag or cover to protect your camera from water spray.
