Diamond Head Summit Trail

The Diamond Head Summit Trail is one of Oahu’s most iconic hikes, located just minutes from Waikiki. This relatively short yet moderately steep trail leads you through a historic volcanic crater, up stairs and tunnels, and ultimately to a breathtaking viewpoint. From the summit, hikers are rewarded with sweeping views of Waikiki Beach, the Pacific Ocean, and Honolulu’s skyline, making it ideal for sunrise or early morning hikes. Reservations and entry fees may apply, so plan ahead to ensure a smooth visit.

Manoa Falls Trail

For those seeking a lush rainforest experience, the Manoa Falls Trail offers a gentle, shaded walk suitable for families and beginners. The well-trodden path winds through bamboo groves and tropical vegetation, culminating at the base of a picturesque waterfall. While swimming is not recommended due to safety concerns, the serene setting and cool valley breeze provide a refreshing escape from the city. Because this area can be muddy and slippery, it is wise to wear sturdy footwear and check weather conditions before your hike.

Koko Crater Railway Trail

The Koko Crater Railway Trail, also known as Koko Head, is best suited for experienced or fit hikers. This challenging route follows an old railway track straight up the side of the crater, with over 1,000 railroad ties functioning as steep steps. Despite the demanding ascent, hikers are rewarded at the top with panoramic views of Hanauma Bay, the southeastern coastline, and the surrounding craters. Start early to avoid midday heat, carry plenty of water, and take your time on the descent to protect your knees.

Lanikai Pillbox And Makapuu Lighthouse

The Lanikai Pillbox (Kaiwa Ridge) hike is a favored sunrise trail, offering stunning views of the Mokulua Islands and Lanikai’s turquoise waters. Short but moderately steep, it includes some rocky sections, yet the colorful World War II bunkers and coastal scenery make the effort worthwhile.

Meanwhile, the Makapuu Lighthouse Trail provides an easier, paved alternative with equally impressive vistas. This family-friendly route leads to an overlook above the historic lighthouse, and during winter months, it is an excellent spot for whale watching. Because the trail is fully exposed, sun protection and water are essential.

Finding the Best Hiking Trails in O‘ahu, HI

How can I find the best hiking trails on O‘ahu for my skill level?

Start by assessing your fitness level, comfort with elevation gain, and preferred hike duration. Then, use reputable sources such as Hawai‘i State Parks, AllTrails, and local hiking clubs to filter hikes by difficulty and distance. Easy options include coastal and botanical garden trails, while intermediate hikers often enjoy ridge hikes with moderate elevation. Advanced hikers may prefer longer ridge lines and summit trails. Always read recent reviews and trip reports to understand current trail conditions, mud levels, and any closures before choosing a hike.

What are some popular but safe beginner-friendly hikes on O‘ahu?

Some of the most accessible hikes for beginners include the Makapu‘u Point Lighthouse Trail, Manoa Falls Trail when open, and the paved paths within Koko Crater Botanical Garden. These options offer clear, well-defined routes with moderate elevation and scenic coastal or waterfall views. When selecting a beginner hike, look for maintained trails with good signage, avoid unofficial shortcuts or steep side trails, and choose routes with plenty of daylight buffer so you are not returning in the dark. Always check for official closures or parking restrictions before you go.

How do I avoid unsafe or illegal hiking trails on O‘ahu?

To avoid unsafe or illegal trails, rely on official sources such as Hawai‘i State Parks, Honolulu Department of Parks and Recreation, and sanctioned trail organizations for up-to-date information. Avoid routes that require trespassing on private property, crossing clearly posted “No Trespassing” signs, or climbing fences. Be cautious with social media recommendations that promote rooftop views, waterfall cliff jumps, or narrow ridges labeled as “secret” or “off-limits.” Stick to legal, maintained trails, and pay attention to posted warnings about landslides, flash floods, or unstable cliffs to reduce your risk of injury and fines.

What should I check in trail reviews before hiking on O‘ahu?

When reading trail reviews, focus on recent comments about mud, overgrowth, and slippery sections, as conditions on O‘ahu can change quickly with rain. Look for mentions of stream crossings, narrow ridges, exposure to drop-offs, and the presence of ropes or scrambling sections if you prefer to avoid technical terrain. Check notes on parking availability, break-in risks, and restroom access. It is also helpful to see reported hike times compared to the listed duration, which can indicate whether a trail tends to take longer than expected due to terrain or crowding.

What gear and preparation are recommended for hiking trails on O‘ahu?

Wear sturdy, closed-toe footwear with good traction, as many O‘ahu trails are muddy and steep. Bring at least one to two liters of water per person for shorter hikes, more for longer or exposed routes, along with sun protection, insect repellent, and a light rain jacket. Download offline maps and directions ahead of time since cell service can be unreliable in valleys and ridges. Start early to avoid midday heat and allow extra time in case conditions are slower than expected. Inform someone of your intended route and expected return time, and avoid hiking alone on remote or advanced trails.
