Less than two miles of trail gets you above Waikiki with a view that stretches from Koko Head to Pearl Harbor. That’s the Diamond Head Summit Trail, and it’s the most-visited hike in Hawaii for good reason — roughly 3,000 people a day make the 0.8-mile climb up through an old military tunnel system to the crater rim. This article covers eight of the best hikes across four islands, from paved family walks to the kind of ridge traverses that make you earn every step. I’ve grouped them by island so you can match a trail to your itinerary, and I’ve flagged which ones Lily and Ethan could handle on our own trips versus the ones Michael and I saved for a solo morning.
Eight trails across four islands — from a paved 2-mile lighthouse walk to an 11-mile Na Pali Coast trek that requires a permit lottery.
Hawaii’s hiking is as varied as its islands, but the best views come with real logistical hurdles — reservations, flash-flood risk, and parking lots that fill before sunrise. Pick the trail that matches your fitness and your planning bandwidth, then start earlier than you think you need to.

| Trail | Island | Distance | Time Needed | Key Tip |
|---|---|---|---|---|
| Diamond Head Summit Trail | Oahu | 1.6 miles round trip | 1.5–2 hours | Reserve at gostateparks.hawaii.gov; the $5 entry fee and timed slots book out days ahead in peak season. |
| Makapuu Lighthouse Trail | Oahu | 2 miles round trip | 1–1.5 hours | No reservation needed; winter mornings offer the best whale-watching from the clifftop. |
| Manoa Falls Trail | Oahu | 1.6 miles round trip | 1–1.5 hours | Muddy year-round — wear closed-toe shoes with good traction, not sandals. |
| Koko Crater Railway Trail | Oahu | 1.2 miles round trip (1,048 stairs) | 1–2 hours | Go at sunrise to beat heat and crowds; free parking at Koko Crater Botanical Garden lot fills by 7 a.m. |
| Kalalau Trail (to Hanakapiai Beach) | Kauai | 4 miles round trip | 3–4 hours | Day permit required via Haena State Park reservation (gostateparks.hawaii.gov); stream crossings flood after rain — check conditions before starting. |
| Pipiwai Trail to Waimoku Falls | Maui | 4 miles round trip | 2–3 hours | Drive the Road to Hana early; the Kipahulu entrance to Haleakala National Park has limited parking that fills by mid-morning. |
| Sliding Sands Trail (Haleakala) | Maui | 2–11 miles (out-and-back options) | 2–6 hours | Summit entrance requires advance timed entry at recreation.gov; altitude starts at 10,023 feet — pace yourself and bring layers. |
| Kilauea Iki Trail | Big Island | 4 miles loop | 2–3 hours | Check nps.gov/havo for trail closures; volcanic activity can shut the crater floor without warning. |
Oahu: The Most Accessible Trails for Big Views
Oahu has the largest trail network of any Hawaiian island, spanning two volcanic mountain ranges. That means you can go from a paved coastal walk to a steep ridge scramble in the same morning, and most trailheads are within a 30-minute drive of Waikiki. These four trails cover the range — easy, moderate, and genuinely hard — so you can pick what fits your day.
Book at gostateparks.hawaii.gov — same system handles Haena State Park on Kauai. Slots release 30 days ahead and weekend morning windows go fast. Pick the earliest available time if you want decent light and shade on the trail.
The trailhead parking lot inside the crater holds about 200 cars. If it’s full, you queue at the gate — expect a 15–30 minute wait even with a reservation. Bring exact change for the $5 entry fee per person (cash or card accepted at the booth).
The trail climbs 560 feet through a dark tunnel and up a narrow spiral staircase built into an old military bunker. It’s the steepest section, and it gets congested — let faster hikers pass on the stairs. Once you emerge at the summit deck, the view takes in Waikiki, the Honolulu skyline, and the southeast coast all the way to Koko Head.
The walk down takes about 20 minutes. If you have time, circle the crater floor on the unpaved trail past the old gun emplacements — it adds another 30 minutes and gives a completely different perspective of the crater walls. If you’re short on time, skip it and head to the next trail on this list.
If you’re looking for a detailed breakdown of the Diamond Head experience — including how to handle the reservation system and what to pack — our local’s guide to hiking Oahu’s Diamond Head covers the full route with parking tricks and timing advice.
Heading into the windward side, the terrain changes from dry crater slopes to green coastal cliffs.
Two more Oahu trails worth your time, depending on how much effort you want to put in.
Kauai: The Dramatic Coast and the Permit You Need
Kauai’s Na Pali Coast is the most photographed coastline in Hawaii, and the Kalalau Trail is how you get into it. But the full 11-mile trek to Kalalau Beach requires an overnight permit obtained through a lottery system, and even the day-hike section to Hanakapiai Beach demands a reservation months in advance. This is the trail that rewards serious planning.
Stream crossings on the Kalalau Trail flood dangerously after heavy rain. Check the National Weather Service’s flash flood advisory for Kauai before you start, and turn back if the water is moving fast or above knee height. The stream to Hanakapiai Falls has claimed lives in flash floods.
Maui: Bamboo Forest and a Martian Crater
Maui offers two completely different hiking experiences: a lush bamboo forest walk to a 400-foot waterfall, and a descent into the otherworldly Haleakala crater. Both require advance planning — the Pipiwai Trail is at the end of the Road to Hana, and Haleakala’s summit requires a timed entry reservation. Pick one or both, but don’t try to do both in the same day unless you’re comfortable with 5+ hours of driving.
Big Island: Walk Across a Volcanic Crater
The Big Island’s Kilauea Iki Trail is the only hike on this list that takes you across the floor of an active volcano’s cooled lava lake. It’s a 4-mile loop that starts and ends in rainforest on the crater rim, descends through a native ʻōhiʻa lehua forest, and crosses the still-steaming crater floor. The trail is in Hawaii Volcanoes National Park, which charges a $30 per vehicle entry fee (valid for seven days). Check nps.gov/havo before you go — volcanic activity can close the crater floor without notice, and the park has evacuated hikers during eruptions.
Practical Section: What You Need to Know Before You Go
Reservations and Permits
Three of the trails on this list require advance reservations: Diamond Head (gostateparks.hawaii.gov, $5 entry), Kalalau Trail/Haena State Park (same system, day-use permit required), and Haleakala sunrise/timed entry (recreation.gov, $1 reservation fee plus park entry). The Diamond Head and Haena slots release 30 days ahead, and weekend morning windows for both typically sell out within hours of release. If you’re flexible on dates, book a weekday morning — availability is significantly better. For the Kalalau Trail’s full 11-mile section to Kalalau Beach, an overnight permit is required via a lottery system that opens 90 days in advance.
What to Pack for a Hawaii Hike
Every trail on this list demands closed-toe shoes with good traction — the mud on Manoa Falls and the lava rock on Kilauea Iki will punish sandals. Bring at least one liter of water per hour of hiking; Hawaii’s humidity and UV intensity dehydrate you faster than mainland hikes at the same elevation. Sunscreen, a hat, and a light rain jacket cover most conditions. For the higher elevation trails (Haleakala and Mauna Kea), add a windproof layer, gloves, and a warm hat — summit temperatures can drop into the 40s even in summer.
On our last trip, I packed a solar-powered smartwatch with multi-sport GPS to track elevation gain and pace on the steeper trails — the built-in flashlight came in handy for the early-morning start at Koko Crater, and the 48-day battery meant I didn’t have to carry a charger for the whole two-week trip.
On the Kalalau Trail day hike, turn around at Hanakapiai Beach — don’t push up to Hanakapiai Falls unless you have 2–3 extra hours and checked the stream conditions. The falls are impressive, but the stream crossing after rain can turn a manageable day hike into a risky one. Lily and Ethan stayed at the beach with a friend while Michael and I did the falls section, and even then the knee-deep water crossing made me nervous.
When to Hike and What to Skip
Start every hike by 7 a.m. — afternoon clouds obscure summit views on Diamond Head and Haleakala, trade winds pick up on coastal trails like Makapuu, and afternoon rain is common on windward trails like Manoa Falls and Pipiwai. If you’re short on time, prioritize Diamond Head and Makapuu on Oahu (you can do both in one morning with a quick drive between them), and skip the full Koko Crater climb unless you’re training for something. On Maui, the Pipiwai Trail is more accessible for a single day than Sliding Sands, which demands a full morning and altitude preparation.

Before You Go: Hawaii Hiking Questions Answered
Do I need hiking boots for Hawaii trails?
Not necessarily, but you need closed-toe shoes with good traction. The paved trails (Diamond Head, Makapuu) are fine in sturdy sneakers. For muddy trails like Manoa Falls or the volcanic terrain of Kilauea Iki, trail runners or lightweight hiking shoes with decent tread are better than stiff boots — they dry faster and grip better on wet lava rock.
Are Hawaii trails safe for kids?
Yes, with the right trail choice. Diamond Head (1.6 miles, paved), Makapuu Lighthouse (2 miles, paved), and Manoa Falls (1.6 miles, muddy but flat) are all doable for children who can walk 1–2 hours. The Koko Crater stairs and the full Kalalau Trail are not kid-friendly — steep drop-offs, stream crossings, and extreme sun exposure make them adult-only hikes. Our rule was: if the trail has a railing or a paved surface, Lily and Ethan could do it. If it required hands-on scrambling or had cliff exposure, Michael and I traded off solo mornings.
What’s the biggest risk on Hawaii trails?
Flash flooding in stream valleys, especially on Kauai and the windward sides of Oahu and Maui. The Kalalau Trail’s Hanakapiai stream crossing has claimed multiple lives in flash floods. Always check the National Weather Service flash flood advisory before hiking any trail that crosses a stream, and turn back if water is moving fast or above knee height. The second biggest risk is sun exposure on exposed ridgelines — Koko Crater and the Sliding Sands Trail have zero shade, and heat exhaustion is common among hikers who don’t bring enough water.
Can I hike without a reservation?
Yes — most trails in Hawaii don’t require reservations. Makapuu Lighthouse, Manoa Falls, Koko Crater, Pipiwai Trail, and Kilauea Iki are all first-come, first-served. Only Diamond Head, Haena State Park (Kalalau Trail), and Haleakala sunrise/timed entry require advance booking. If you show up without a reservation for those three, you’ll be turned away at the gate.
What’s the best single-day hike on each island?
Oahu: Diamond Head for the iconic view, or Makapuu Lighthouse for the easiest big payoff. Kauai: the first 2 miles of the Kalalau Trail to Hanakapiai Beach. Maui: Pipiwai Trail through the bamboo forest to Waimoku Falls. Big Island: Kilauea Iki loop across the crater floor. Each of these can be done in half a day and gives you a genuine sense of that island’s landscape.
The Takeaway: Pick the Hike That Fits Your Trip, Not Your Feed
The best Hawaii hike isn’t the one with the most Instagram saves — it’s the one you actually finish without regretting your footwear choice or your start time. Diamond Head and Makapuu deliver big views for small effort, Pipiwai and Kilauea Iki reward you with landscapes you can’t find anywhere else, and the Kalalau Trail is worth every bit of the planning hassle if you have the fitness and the permits. Match the trail to your day, not the other way around.
