Hawaii’s Lost Valley: Hiking to Waterfalls in Nu’uanu Valley

Escape the Waikiki crowds and discover a hidden paradise just minutes away: Nu’uanu Valley, home to what many call ‘Lost Valley.’ This lush, green valley offers a range of hiking options, from leisurely strolls to challenging climbs, all rewarded with stunning waterfalls and panoramic views. This article is your comprehensive guide to exploring Nu’uanu Valley, covering everything from the best trails and what to pack to essential safety tips and local insights.

Understanding Nu’uanu Valley’s Allure

Nu’uanu Valley isn’t just another pretty place in Hawaii; it’s a location steeped in history and shrouded in mystique. Its name, meaning “cool heights,” hints at the cooler temperatures and abundant rainfall that contribute to its dense vegetation. More importantly, it’s a significant historical site. This valley was the location of the Battle of Nu’uanu Pali in 1795, where King Kamehameha I secured his victory, unifying the islands. Legend says warriors plunged to their deaths from the towering cliffs of the Pali Lookout rather than face defeat. Today, the Pali Lookout (officially called the Nu’uanu Pali State Wayside) offers dramatic views of the windward coast and serves as a somber reminder of this pivotal moment.

Beyond its historical significance, Nu’uanu’s unique geography creates a microclimate perfect for growing a wide variety of plants and trees. This is evident in the area’s lush rainforest, teeming with life. It is even home to endangered species. It’s a place where you can truly feel disconnected from the hustle and bustle of Honolulu, even though you’re so close.

Trail Options: Choosing Your Adventure

Nu’uanu Valley provides options for all fitness levels and time constraints. Remember that conditions can change rapidly and trail closures are possible, so it’s always a good idea to check current conditions before heading out.

Aukahi Street Trail (aka Lulumahu Falls Trail)

The most popular and well-known trail in Nu’uanu is the one that leads to Lulumahu Falls. However, this is not a officially sanctioned trail and requires a permit. This roughly 2-mile round trip trek brings you right through the heart of the valley. This is the trail when people mention hiking through a tunnel of vegetation. It consistently requires wading through knee-deep water, so wear appropriate footwear (reef shoes or sturdy hiking sandals). The trail can be muddy and slippery, especially after rain.

Getting There: The trailhead starts at the end of Aukahi Street, in a residential neighborhood. Parking is extremely limited and you will need to walk a bit. Be very respectful of the neighborhood and don’t block driveways.

Permit Information: Access requires obtaining a permit from the Division of Forestry and Wildlife (DOFAW). Permits are free, but required, and help manage the impact of visitors on the delicate ecosystem. You do not have to do a guided hike to access the permit. Apply for the permit online well in advance of your hike, as they can book up.

What to Expect: The trail follows an old aqueduct system. You’ll encounter stream crossings and navigating uneven terrain. The payoff is the 50-foot Lulumahu Falls, cascading into a refreshing pool. The “jungle” aesthetic has made this fall incredibly popular and has been featured in multiple movies and TV shows. Because it’s become much more popular, the falls and trails can be pretty crowded, especially on the weekends.

Nu’uanu Trail

For a longer and more challenging experience, consider the Nu’uanu Trail. This trail provides a broader view of the valley and interconnects with other trails. This is also part of the original ‘Oahu Trail System’ that once circled most of the island of Oahu.

Getting There: Trailheads exist at different points throughout the valley. Some access points are near the Pali Lookout. Parking is either at the Lookout or in designated pullouts along the Pali Highway (Highway 61). Use caution when crossing the highway as traffic can be fast-moving.

What to Expect: The Nu’uanu Trail is well-maintained for much of the way, but it can still be muddy in sections. Expect elevation gains and some steeper climbs. You’ll be rewarded with panoramic views of the valley and the surrounding Ko’olau mountains.

Judd Trail / Jackass Ginger Pool

Consider the Judd Trail, which provides a relatively easier hike to a refreshing swimming spot: the Jackass Ginger Pool. This is often used as a fun family friendly alternative to Lulumahu falls. This is another hike with wading required, so be sure to wear appropriate footwear.

Getting There: The trailhead is located off Nu’uanu Pali Drive. There is designated parking available.

What to Expect: The trail is a short loop, suitable for beginners. It passes through a verdant forest before arriving at the Ginger Pool, a natural pool fed by a small waterfall. It’s a great place for a quick dip and a picnic.

Essential Gear and Preparation: Setting Yourself Up for Success

Preparation is key to enjoying any hike. Here’s what you should bring:

  • Water: Staying hydrated is critical, especially in Hawaii’s humid climate where you can sweat like crazy. Bring at the very least 2 – 3 liters of water per person when hiking in Hawaii.
  • Snacks: Pack energy bars, fruit, or trail mix to keep your energy levels up.
  • Sunscreen and Hat: Protect yourself from the sun, even on cloudy days. The sun is always strong in Hawaii.
  • Insect Repellent: Mosquitoes and other insects can be prevalent, especially in the damper areas of the valley. Bug spray that contains DEET is always best.
  • Appropriate Footwear: Sturdy hiking shoes or reef shoes are essential. Trails can be slippery and involve stream crossings. Closed-toe shoes are highly recommended.
  • Rain Gear: Nu’uanu is known for its rainfall, so pack a light rain jacket or poncho.
  • First-Aid Kit: Carry a basic first-aid kit for minor cuts and scrapes.
  • Backpack: A comfortable backpack is essential carrying gear.
  • Fully charged cell phone: to be able to communicate in case of an emergency. Download offline trails map for your phone.

Pro Tip: Consider bringing a dry bag to protect your electronics and valuables from water damage.

Safety First: Navigating the Nu’uanu Trails Responsibly

Safety should always be your top priority when hiking in Nu’uanu Valley. Here are some key considerations:

  • Check the Weather: Be aware of the weather forecast before you go and avoid hiking if heavy rain is predicted. Flash floods can occur rapidly in the mountains.
  • Stay on Marked Trails: Stick to established trails to avoid getting lost and minimize your impact on the environment.
  • Hike with a Buddy: It’s always safer to hike with a companion. Inform someone of your hiking plans and estimated return time.
  • Watch Your Step: The trails can be uneven and slippery, so pay attention to your footing.
  • Be Aware of Falling Rocks: The cliffs in Nu’uanu are prone to rockfalls, especially after rain. Be cautious when hiking near cliffs.
  • Respect Wildlife: Observe wildlife from a distance and do not feed the animals. Protect Hawaii’s fragile ecosystem.
  • Pack Out What You Pack In: Leave no trace behind. Take all trash with you.

Important Information: Trail conditions in Nu’uanu can change rapidly, especially due to weather. Always check for any alerts or closures before heading out. Websites like the Hawaii Department of Land and Natural Resources (DLNR) can provide updates on trail conditions.

Local Insights: Enhancing Your Nu’uanu Experience

To truly appreciate Nu’uanu Valley, consider these local insights:

  • Use a Polarizing Filter: A polarizing filter can help reduce glare and reflections, enhancing the colors of the foliage and water.
  • Capture the Waterfalls: Experiment with different shutter speeds to capture the movement of the waterfalls. A slow shutter speed can create a silky, dreamy effect.
  • Look for Details: Don’t just focus on the big picture. Look for interesting details like ferns, flowers, and interesting rock formations.
  • Protect Your Gear: The valley can be damp, so protect your camera gear from water damage. Consider using a waterproof camera bag or a rain cover.

Photography Tip: Overcast days can actually be ideal for photographing waterfalls, as the soft, even light eliminates harsh shadows and highlights.
