Exploring Oahu’s Natural Wonders: Best Hikes on the Island

Oahu, often called “The Gathering Place,” holds the title of “Most Scenic Island” for its stunning landscapes. It is ranging from pristine beaches to lush rainforests, and even dramatic viridescent mountain ranges. One of the best ways to experience the island’s diverse terrain and natural wonders all at once is through hiking! Whether you’re an experienced trekker or a casual walker seeking an adventure, Oahu offers a variety of trails that will ensure you break a sweat as well as cater to all levels of fitness and interest. Here’s a guide to some of the best trails on Oahu, promising unforgettable experiences and phenomenal views. 

1. Diamond Head Summit Trail

One of the most iconic and well-known hikes on Oahu, the Diamond Head Summit Trail offers sweeping views of Waikiki and the Pacific Ocean, even sometimes showcasing neighboring islands and sometimes whales during whale season! Located within the Diamond Head State Monument, this moderate hike spans approximately 1.6 miles round-trip. The trail ascends all the way up to the summit of a dormant volcanic crater. Where visitors can explore fascinating military bunkers and enjoy a 360 panoramic view of Honolulu and the Pacific Ocean. The hike is accessible at all times, although is usually crowded, and is best to hike during sunrises and sunsets to avoid the peak heat during the day.

2. Koko Head Railway Trail

For those looking for a more challenging adventure, Koko Head Crater Railway Trail is calling your name! The Koko Head Crater Railway, also known as the Koko Head Stairs, is a favorite among locals and visitors alike. This strenuous hike consists of climbing over 1,000 railroad tie “steps” that lead to the summit of Koko Head. Though the hike is treacherous, the view, said by many, is definitely worth it. Once the summit is reached, hikers are rewarded with breathtaking views of Hanauma Bay, Sandy Beach, and all of the southeastern coastline of Oahu. The Hike is approximately 1.8 miles round trip but like Diamond Head Trail it’s best to go during the early mornings to avoid the middle-day heat. 

3. Makapu’u Lighthouse Trail

Located on the southeastern tip of Oahu, the Makapu’u Lighthouse Trail is definitely one of a kind. The Makapu’u Lighthouse Trail is a scenic route that offers stunning views of the Pacific Ocean below and the rugged coastline. This paved trail spans approximately 2 miles round trip and is suitable for hikers of all skill levels. Even your kids can join in on the fun of this hike! Along the way, hikers can spot unbleached seabirds, whales during whale season, and the historic Makapu’u Lighthouse, which has guided ships since 1909! That’s older than all of you! The trail is relatively easy with gradual inclines, making it quite a popular choice among families and novice hikers just looking for a fun outing!

4. Manoa Falls Trail

Nestled in the lush Manoa Valley, this enchanting hike leading to the leisure Moana Falls has visitors and locals stunned by its remarkable beauty. A 150-foot cascade surrounded by vibrant vegetation. The trail is well-maintained and is a relatively easy hike, making it perfect for family, beginner hikers, or someone just looking for some exercise while admiring lush scenery. While hiking the trail, you’ll encounter bamboo grooves, tropical flora, and perhaps even a glimpse at some native tropical birds. The cool mist and tranquil ambiance near the waterfall offer a refreshing retreat from the island’s warmth. Making it a popular favorite among many. 

5. Ka’ena Point Trail

Venture to Oahu’s westernmost tip to explore the serene wonders of Ka’ena Point Trail, a coastal trek offering unspoiled natural beauty and wildlife encounters. The trail can be through the north or south shore. Making it more of an easily accessible trail along with giving visitors a choice on which trail to trek. Both routes provide scenic views of rugged cliffs, turquoise, azure waters, and hot rolling surf! Ke’ena Point Trail is a protected natural reserve, home to seabirds, Hawaiian monk seals, and other endemic species. The hike is relatively flat and not too steep making it a relatively easy hike. Perfect for families and novice hikers! Ka’ena Point Trail is definitely one of my favorite hikes because of its lush scenery and gentle wildlife. Making it a hot spot for many others too!

6. Lanikai Pillbox Hike

Well known for its stunning sunrise views, the Lanikai Pillbox Hike in Kailua is a short, but steep ascent to the World War II-era bunkers. From the Pillboxes, hikers are rewarded at the end of the challenging, sweat-infusing hike with gorgeous, scenic views of Lanikai Beach, the twin Molukua Islands, and the sparkling azure waters of Kailua Bay. The early morning light casts a golden aura over the landscape, creating a stunning picture-perfect painted scene that’s definitely worth waking up at 4 in the morning for! The trail can get quite crowded as it is quite famous, so arrive early and reserve a spot, and soak up all that relaxation and tranquility!

7. Wiliwilinui Ridge Trail

Though it’s one of the more treacherous hikes on the list, it’s one worth hiking. For a challenging yet rewarding hike away from crowds, head to the Wiliwilinui Ridge Trail up in the Ko’olau Mountains. The breezy trail winds through the native Hawaiian forests and offers breathtaking views of Honolulu, Diamond Head, and the lush Windward coast. The ascent is steep and offers a good level of fitness, so if you’re a beginner hiker I definitely recommend trenching a different trek. However, the solitude and stunning views at the summit make it a hit favorite among seasoned hikers. Be prepared with ample water and sun protection as there is limited shade along the trail.

Tips for Hiking on Oahu

• Prepare Adequetly: Wear sturdy hiking shoes or sandals, and carry plenty of water, sunscreen, and insect repellent.

• Respect Oahu’s Wildlife and Nature: Stay on designated trails, be sure to avoid stepping on any native plants, PACK OUT WHAT YOU PACK IN, and respect wildlife and local culture. 

• Check Trail Conditions: Some trails may be closed due to weather conditions or maintenance, so check local guides or visitor centers before setting out. I also recommend going on a clear day to ensure you don’t slip on any muddy trails or roast in the hot sun when hiking. 

• Start Early: Beat the heat and crowds by starting your hikes early in the morning (recommended times: 4 AM to 5 AM), especially for more popular trails such as Diamond Head Summit Trail and Lanikai Pillbox.
