Hawaii’s hiking trails are legendary, offering everything from challenging climbs to breathtaking coastal walks. From lush rainforests to volcanic landscapes, there’s a trail for every skill level. This guide dives into some of the absolute best, providing you with the details you need to plan your incredible Hawaiian adventure.
Oahu: The Gathering Place of Hiking Gems
Oahu, known as “The Gathering Place,” is a hiker’s paradise, boasting a diverse range of trails accessible to various experience levels. You’ll find everything from relatively easy nature walks to strenuous climbs that reward you with panoramic vistas.
Diamond Head Summit Trail
One of the most iconic hikes on Oahu is the Diamond Head Summit Trail. This 1.6-mile roundtrip hike is moderately challenging, with a steep climb to the summit of this volcanic tuff cone. The trail features paved walkways and stairs, making it accessible for most fitness levels. As you ascend, you’ll pass through old military bunkers and tunnels, remnants of Diamond Head’s past as a strategic defense point. The panoramic views from the summit are absolutely stunning, offering sweeping vistas of Waikiki, the Pacific Ocean, and the surrounding coastline.
What to Expect: Expect crowds, especially during peak season (winter) and weekends. Bring water and sunscreen as there’s limited shade. The hike typically takes 1.5 to 2 hours to complete. Make sure to reserve your entry and parking spot ahead of time on the Diamond Head State Monument website. The fee is $5 per vehicle for parking or $1 per walk-in visitor.
Getting There: Diamond Head State Monument is located in Honolulu, near Waikiki. From Waikiki, you can take TheBus (route 23) or drive yourself. Parking is limited, so arrive early or consider using a rideshare service.
Manoa Falls Trail
For a taste of lush Hawaiian rainforest, head to Manoa Falls Trail. This 1.6-mile roundtrip hike takes you through a verdant valley, passing towering trees, bamboo forests, and a variety of tropical plants. The trail can be muddy, especially after rain, so wear appropriate footwear (hiking boots are recommended). The destination is the magnificent Manoa Falls, a 150-foot waterfall cascading down a cliff face. Swimming in the pool at the base of the falls is discouraged and potentially dangerous due to falling rocks and leptospirosis risks.

Getting There: Manoa Falls Trailhead is located in the Manoa Valley. From Waikiki, take H-1 West to Manoa Road. Follow Manoa Road to the end, where you’ll find the trailhead.

FAQ Section
What is the best time of year to hike in Hawaii?
The best time to hike in Hawaii is during the shoulder seasons: spring (April-May) and fall (September-October). These months offer pleasant weather with less rainfall than the winter months and fewer crowds than the summer months. Keep in mind that Hawaiian weather can be unpredictable so check local forecasts and be prepared for rain at any time of year.
Do I need a permit to hike in Hawaii?
Permits are required for certain trails and activities, especially for camping. The most notable example is the Kalalau Trail on Kauai. Check with the specific park or trail authority to determine if a permit is required and how to obtain one. Many permits can be reserved online weeks or even months in advance.
What are the dangers of hiking in Hawaii?
Hiking in Hawaii can present several risks. These include: Flash floods particularly in valleys and near streams; exposure to strong sun leading to sunburn and dehydration; slippery trails due to rain and mud; falling rocks, especially near cliffs; dangerous currents when swimming in the ocean; and potential encounters with wildlife such as feral pigs. Always exercise caution, stay informed about weather conditions, and be prepared for potential hazards.
Are there any poisonous plants or animals to be aware of?
While Hawaii has relatively few dangerous animals, there are some plants to be aware of. Poison ivy is not found in Hawaii, but pūkiawe (Styphelia tameiameiae), while not poisonous, can cause skin irritation. Be cautious when touching unfamiliar plants. Mosquitoes can also carry diseases like Dengue Fever. No snakes exist in Hawaii but centipedes, though painful, aren’t deadly.
What should I do if I encounter a wild animal on the trail?
If you encounter a feral pig, monitor its behavior. Make noise and slowly back away, providing a clear escape route for the animal. Never approach or feed wild animals. If you see a Hawaiian monk seal on a beach or near the coast, maintain a safe distance as these are endangered animals.
