If you’re headed to the stunning Hawaiian Islands soon, specifically Oahu, and are looking for some incredible hikes, you’re in the right place! After living in Honolulu for several years, I’ve compiled a list of my favorite hikes on the island. Oahu is a diverse and beautiful place, offering everything from vibrant cityscapes to tranquil beaches and lush, green mountains. Whether you’re exploring the North Shore, lounging on the East Side, or hiking through the island’s countless trails, there’s something for everyone.
Oahu boasts hundreds of hiking trails, each offering unique views, hidden waterfalls, and tranquil panoramas. The island’s green landscapes and dramatic ridges make it one of the world’s most beautiful hiking destinations. From easy strolls to challenging ascents, I’ve included a variety of hikes with different difficulty levels. As always, please respect the land, stay safe, and be prepared. Oahu is a sacred place for locals, and responsible hiking is essential for preserving its natural beauty.
1. Koko Head Crater
• Distance: 0.8 miles (1.3 km)
• Elevation Gain: 1,200 feet (366 meters)
• Difficulty: Challenging
• Time to Complete: 30-45 minutes
• Location: Southeast Oahu, near Hawaii Kai
• Popularity: High
Koko Head Crater is my go-to hike on Oahu and a perfect outdoor workout. This short but steep trail was once a military lookout, and you’ll follow a tramway that brought supplies to the top. The trail is a straight line of steps that climb up the mountain’s face. Despite being under a mile long, the incline makes it a tough workout, particularly for the lower body. Locals often use it as a “nature stair climber,” hiking up multiple times a day. Once at the summit, you’re treated to stunning panoramic views of the island, from the cityscape to the East Side, and on clear days, even nearby islands. Whale sightings are common in winter!
2. Pink Pillbox Hike
• Distance: 1.6 miles (2.6 km)
• Elevation Gain: 1,200 feet (366 meters)
• Difficulty: Moderate
• Time to Complete: 1-2 hours
• Location: West Oahu, near Waianae
• Popularity: Moderate
The Pink Pillbox Hike is a hidden gem on the West Side of the island. It’s a moderate, 1.6-mile climb with a series of switchbacks. Once at the top, you’ll be rewarded with sweeping views of the ocean and the rugged coastline of the island. The hike is especially popular for watching the sunset, with the sun setting directly over the water. Be sure to wear sturdy shoes as the terrain can be uneven and rocky. It’s a well-loved trail, so try to go early or at sunset to avoid crowds.
3. Lanikai Pillbox Hike
• Distance: 1.4 miles (2.3 km)
• Elevation Gain: 700 feet (213 meters)
• Difficulty: Moderate
• Time to Complete: 45 minutes to 1 hour
• Location: Kailua, East Oahu
• Popularity: High
Lanikai Pillbox is one of the most popular hikes on Oahu, known for its stunning views of the Mokulua Islands and Lanikai Beach. This trail is relatively short, but it does feature some steep sections and ropes to help you up the incline. It’s best done at sunrise to enjoy fewer crowds and beautiful early morning light. However, be aware that the trail can get quite muddy during the rainy season, so check the weather before heading out. The hike offers a 360-degree view, making it one of Oahu’s most scenic trails.
4. Wiliwilinui Ridge Trail
• Distance: 4.7 miles (7.6 km)
• Elevation Gain: 1,600 feet (488 meters)

For those looking for a more strenuous hike, Wiliwilinui Ridge offers a challenging 4.7-mile trail with steep inclines and stairs. As you climb, you’ll be rewarded with panoramic views of the East Side of the island, including the Ko’olau Mountain Range. The hike is known for its muddy conditions, so come prepared with waterproof shoes. The summit often brings hikers above the clouds, making for a surreal experience. Be sure to obtain a free parking permit before heading out. This trail is less crowded than other popular hikes, so it’s great for those seeking solitude in nature.
5. Lulumahu Falls
• Distance: 2 miles (3.2 km)
• Elevation Gain: 800 feet (244 meters)
• Difficulty: Moderate
• Time to Complete: 1.5-2 hours
• Location: Nuuanu Valley, Central Oahu
• Popularity: Low
Lulumahu Falls is a lesser-known trail that ends at a beautiful 50-foot waterfall. The hike takes you through a bamboo forest, across streams, and up a mountainous path. It’s a 2-mile round trip, and the trail is not well-marked, so I recommend downloading an offline map. Be mindful of the slippery terrain, especially during the rainy season. The area is prone to heavy rainfall, so expect muddy and sometimes challenging conditions. There’s no official parking for this trail, so it’s best to get dropped off or park along the Pali Highway. Keep your belongings secure, as thefts can occur in this area.
6. Makapu’u Lighthouse Trail
• Distance: 2.5 miles (4 km)
• Elevation Gain: 500 feet (152 meters)

This is a relatively easy hike on a paved path that takes you up to the Makapu’u Lighthouse, offering stunning views of the southeastern coast and Koko Head Crater. The hike is perfect for beginners or anyone looking for a leisurely stroll with beautiful scenery. The gradual incline makes it an easy trek, and once at the top, you can enjoy sweeping ocean views. The hike is especially popular during whale season, where you can spot humpback whales off the coast. It’s also a great spot for a sunrise view, though it can get crowded later in the day.

This 1.6-mile trail is well-maintained and takes you through a lush tropical rainforest to a picturesque 150-foot waterfall. It’s an easy, family-friendly hike, though it can get muddy after rain. This is a very popular trail, so expect crowds, especially on weekends. The waterfall is too dangerous to swim in, but it makes for great photos. Be prepared for rain, as the area is known for its wet conditions.
8. Aiea Loop Trail

Located in the Keaiwa Heiau State Recreation Area, the Aiea Loop Trail is a popular, moderate hike that offers stunning views of the forest, the Aiea Bay, and the surrounding mountains. The trail is not particularly difficult, but it is longer than most, with gradual inclines throughout. It’s a great option for those looking for a hike that’s not too challenging but still offers some beautiful scenery. The trail is moderately crowded, especially on weekends, but it’s still an enjoyable escape into nature.

The trail itself is about 10 miles long with significant elevation gain, making it physically demanding. It’s not recommended for beginners, as it’s long, muddy, and includes technical sections. You’ll need proper footwear and plenty of water for this one, and be sure to follow all local regulations.
