Honolulu is uniquely nestled between the majestic Ko‘olau and Wai‘anae mountain ranges, offering hiking experiences for all levels—from easy strolls to challenging climbs. Whether you’re seeking vibrant flora, cascading waterfalls or panoramic vistas, the trails through native forests and stunning mountain ranges provide a perfect escape into nature without leaving the city behind.

Clean Your Shoes: Brush off your shoes before and after hikes to prevent invasive species from spreading. Many O‘ahu trails now have boot cleaning stations or running water to make this easier.

Preserve Native Flora: Hawai‘i’s endemic plants are rare, and many species have already disappeared. Be mindful of your surroundings and avoid disturbing or removing plants and wildlife.

Respect Trail Guidelines: Stick to marked trails to protect delicate ecosystems. Off-trail wandering can harm fragile flora and fauna.

Hydrate and Protect Yourself: The Hawaiian sun can be intense, even in shaded areas. Bring plenty of water, wear sunscreen, pack a hat for protection, and bring mosquito repellant.

Leave No Trace: Pack out everything you bring, including trash and food scraps, to keep the trail clean and undisturbed.

Check Trail Conditions: Some trails may be closed or affected by weather. Always check conditions before heading out, especially for flood risks in areas like Makiki Valley Loop or Mānoa Falls.

Hike with a Buddy: Hiking with a friend or group is safer. If going solo, share your route and expected return time because cell reception can be spotty on some trails.

Come Prepared: Parking can be limited in Honolulu, especially near popular trails. Carpool when possible, and avoid leaving valuables in your car. Some areas, like Mānoa Falls and Diamond Head, may require cash for parking.

Diamond Head Trail
A classic family-friendly hike with unbeatable views

Diamond Head is one of Honolulu’s most iconic hikes, offering an easy and accessible adventure up one of the island’s most recognizable natural landmarks perfect for families. This well-maintained trail is just a short drive from Waikiki, making it an ultra-accessible day (or even partial day) trip activity. The trek leads you to the summit of Lēahi, a volcanic crater with sweeping panoramic views of the Pacific Ocean, Waikiki Beach and the city skyline at its zenith. The hike is only about 1.5 miles round trip, but the route is dry and definitively uphill (so, yes, you’ll be getting your exercise for the day) with a gradual incline, a few stairways and a tunnel along the way. While the trail is relatively short, it can get quite hot with very little cover from the sun, so be sure to bring plenty of water and wear sunscreen and a hat. Note that there’s an entrance fee of $5 per person, or $10 per vehicle. The views at the top are absolutely worth it, making this one of the best beginner-friendly hikes on Oahu!

dlnr.hawaii.gov/dsp/parks/oahu/diamond-head-state-monument; open 6 a.m. to 6 p.m. daily with last entry at 4 p.m. Online reservations are required for non-residents, available at gostateparks.hawaii.gov/diamondhead.

Lyon Arboretum
A Botanical Experience for Families

A series of excellent trails at Lyon Arboretum takes you up to a waterfall in the back of the valley, through gardens of exotic tropical flora—and around charming garden features like a gazebo and arbor. But honestly, the arboretum is so much more than a hike. There’s so much to explore at this University of Hawai‘i-run garden and many picturesque vistas. While this hilly spot gives you a grand view of expansive lawns and groves of countless trees, the trail incline remains relatively flat, which makes for more of a stroll than a hike. Bring the kids and set them free to roam. Visit the lily pond, Buddha statue, ethnobotanical garden, greenhouse and more. Reservations are required and limited at the arboretum—head to their website to reserve your spot. 

3860 Manoa Rd, Honolulu; (808) 988-0456; manoa.hawaii.edu/lyon; Open Monday through Friday, 9 a.m. to 3 p.m.

Mānoa Falls
A Popular Rainforest Discovery Adventure 

Nearby is Mānoa Falls, which offers dramatic rainforest scenery and lush surroundings, unlike the rambling garden atmosphere of the arboretum. This 1.6-mile hike is an uphill climb, gaining 800 feet in elevation, so be prepared for a bit of a trek. While it's not an expert-level challenge, it’s more than just a stroll—expect to break a sweat as you make your way through a dense jungle with towering trees and ferns lining the trail. The reward at the end is a stunning 150-foot waterfall cascading into a serene pool. Though the trail can get crowded, especially on weekends, it’s a fantastic way to experience the raw beauty of Honolulu’s rainforests. And the best part? Mānoa Falls is just a short drive from downtown and Waikīkī, offering a perfect nature escape close to the city's vibrant dining, shopping and nightlife.

dlnr.hawaii.gov/recreation/nah/oahu; Open daily from 6 a.m. to 6 p.m. There is no parking at Mānoa Falls. The Paradise Park Lot fee is $7. 

Makiki Valley Loop Trail
A Serene Workout
 
The Makiki Valley Loop Trail is a hidden gem in Honolulu, offering a solid workout while remaining much less crowded than popular hikes like Mānoa Falls. A favorite among locals and visitors, the 3.4-mile loop trail winds through lush forest, passing peaceful babbling streams (so be prepared for some mud), with peekaboo city views and glimpses of Hawaiian culture, including an ancient structure and a small taro patch. While the trail doesn’t feature dramatic vistas or waterfalls, its tranquility makes it a perfect spot for “forest bathing.” The 1,000-foot elevation gain provides a good challenge, and if you take the steeper trail to the right at the start of the loop, you’ll get a solid workout. The loop is a convenient hike, but it also connects to several other trails in the Honolulu Mauka Trail System, offering endless opportunities for further exploration and adventure.

dlnr.hawaii.gov/recreation/nah/oahu; open sunrise to sunset. Parking is available on Tantalus Drive or at the Hawaii Nature Center (closes at 6 p.m.).
