Honolulu Hiking Tours

Honolulu Hiking Tours - What to Know

Choosing a guided hiking tour in Honolulu is a game-changer, especially for iconic spots like Diamond Head, Manoa Falls, and the more secluded ʻAihualama Falls Trail. Guides not only help you navigate steep, sometimes slippery terrain, but they also provide the inside scoop on the area's rich history, like WWII bunkers at Diamond Head and the lush, rainforest ecosystems of Manoa Valley. Exploring the rugged Koʻolau Mountains with a guide ensures safety on challenging ridgelines while revealing hidden gems and breathtaking views you might otherwise miss.

Many of these rainforest trails are muddy, slippery and uneven, and high rainfall can make them treacherous. Many of Honolulu's trails are also not well-marked and not maintained by authorities, making them unreliable—particularly in wet conditions. For peace of mind, consider joining a guided hiking tour. Experienced guides can help you navigate safely, share hidden local spots, and teach you about Hawaiian history and cultural insights.

Why Choose Honolulu for Hiking

One of the biggest draws to hiking in Honolulu is the accessibility of its trailheads, just minutes from the city. Whether you're looking for a quick escape into nature or a full-day adventure, Honolulu hiking tours offer the chance to combine activities. Imagine biking through the city streets, then set off on iconic hikes like Manoa Falls or Diamond Head, where you can explore tall waterfalls or the remnants of WWII history as you trek along the volcanic crater ridge.

Backed by the Koʻolau Mountains, Honolulu’s hikes showcase the dramatic ridges and towering cliffs that make Oahu's eastern landscape so iconic. Many of the trails take you through dense rainforests to hidden waterfalls, or along scenic ridgelines with views of the Hawaiian coastline and Honolulu skyline below. It’s a photographer’s paradise, offering the perfect backdrop of cascading waterfalls, colorful flowers, and panoramic views of Honolulu's skyline. With a wide range of trails to choose from, it's easy to avoid the crowds by venturing off the beaten path or opting for early morning or late afternoon hikes.

Where to Go Hiking in Honolulu

Diamond Head

One of Honolulu’s most iconic hikes, Diamond Head offers a relatively short but steep trail up to the summit of a volcanic crater. At the top, you’re rewarded with panoramic views of Waikiki, Honolulu, and the stunning blue Pacific Ocean. The hike is not just about the scenery—it also has historical significance, with old military bunkers and remnants of WWII fortifications along the trail.

Manoa Falls

This beautiful trail takes you through a rainforest to reach the spectacular 150-foot Manoa Falls. The path is typically muddy and slippery due to the frequent rainfall, but the stunning waterfall at the end, surrounded by thick tropical vegetation, makes it worth the effort. The hike is relatively easy, making it a popular choice for families and nature lovers.

ʻAihualama Falls Trail

The ʻAihualama Falls Trail is a hidden gem tucked away in Manoa Valley. The trail can be muddy and slippery, especially after rain, but it leads to the ʻAihualama Falls, a cascading waterfall tucked into the cliffs. The hike is less traveled than nearby Manoa Falls, so it’s perfect for those looking for a quieter, more intimate experience with Oahu’s natural beauty.

Koʻolau Mountains

The Koʻolau Mountain Range stretches along Oahu’s windward side and features dramatic cliffs, lush valleys, and steep ridgelines.

Top Tips for Hiking in Honolulu

• Best Time to Hike: The best time to hike in Honolulu is during the drier months from April to October, when trails are less muddy and the weather is ideal for taking in views. For those looking to avoid crowds, April to June and September to November are slow months for tourism. Please be aware that while December to February bring heavier rains, making waterfalls more impressive, it also significantly increases the risk of flash floods and rock falls around those waterfalls and waterways, so caution is highly advised during this time.
• Follow Leave No Trace Principles: Keep all trash with you and secured in your bag to properly dispose of when you return back to town.
• Properly Layer Clothing: Make sure the clothing is moisture-wicking, lightweight, and fast drying! You may be sweating a lot or it may be raining for short spurts and you will need to dry quickly. Weather can change rapidly, be sure to layer your clothing to avoid getting wet from sweat or being too cold on the trail.
• Wear Proper Footwear: Broken in/Used before with closed toes and grippy tread! Comfortable socks to prevent blisters and small shoe gaiters are helpful to keep rocks and sand from getting into the shoe and causing blisters or cuts. 
• Sunscreen & Sun Protection: Sunscreen, brimmed hats, sunglasses, neck coverings (may attach to hats), and UV deflecting long sleeve shirts can all help to combat the harmful and strong Hawaiian sun rays!
• Mosquito Repellent: Remember to bring bug repellent when heading into the rainforest, swamp, bog, or waterfall areas of Honolulu. There are plenty of mosquitos in those areas.
• Trail Etiquette: Yield to uphill hikers and try to step aside on rocks or wide areas on the trail to protect the landscape. Avoid shortcuts, especially ones that go straight up between switchbacks to protect fragile ecosystems and prevent erosion.
• Carry a Map or GPS: Cell service is especially spotty in remote areas of Honolulu, especially in the valleys between cliffs. Downloading offline maps or bringing GPS devices can become essential in emergencies.
• Respect Wildlife: Observe wildlife from a distance, never chase, harass, or feed them.
• Know your Limits: Monitor for dehydration or heat stroke symptoms such as headaches, disorientation, rapid heartbeat, and nausea or vomiting. Be also monitoring for hypothermia in high altitude places, especially with rain.
• Beware of Ropes: Most Honolulu trails are not maintained by the state, meaning those ropes are placed by other hikers and should never be solely relied on. Also be secure without needing the rope in case it is worn on top and breaks. If you can only climb up by relying on the rope, please turn around for your safety.
• Don’t Swim in Still Water: Honolulu is home to plenty of waterfall hikes that can be slow or drying up. Please do not swim in water that has been slow flowing or still, especially with any cuts or open wounds due to bacteria and issues with Leptospirosis.
