Whether you’re looking for a family-friendly walk or a thrilling adventure, this guide covers the top 25 hikes on Oahu to ensure your hiking experience is unforgettable.
Hiking Essentials for Oahu
Before setting out on any hike, it’s crucial to be prepared. Hawaii’s terrain is diverse, and conditions can change quickly. Here’s a list of must-have gear for your Oahu hikes:
• Reusable Water Bottle (with Filter): Hydration is key, especially in Hawaii’s tropical climate.
• Lightweight Hiking Backpack: A sturdy backpack equipped with a water bladder, snacks, and first-aid kit is essential. A hiking backpack: with a water pack for easy hydration (tip: pick a size based on your hiking needs, I prefer 2-3 liter water packs). I usually carry a smaller backpack like this, and my husband carries a bigger one where I shove all my snacks and goodies! We prefer the screw on water pack/bladder packs, and they are so much easier to use! I also recomend these cleaning tabs to ensure you’re getting your water pack/bladder clean from harmful bacteria.
• Blister bandages: If you are going to be hitting the trails, especially with new boots, do yourself a favor and put these on your heels before the hike and take them incase you get blisters elsewhere!
• Shoe Spikes: Some trails on Oahu are steep and can become muddy, especially after rain. Shoe spikes help with traction and safety on slick terrain.
• Hiking Boots: For rugged hikes, sturdy, waterproof boots with good ankle support are a must. They’ll provide the traction you need on uneven trails. I prefer Danner boots, but here is a cheaper option I had before I upgraded as well. I also love these socks.
• Footwear based on the hike: Pack the right shoes for each adventure I prefer Sandals like Birkenstocks for beach days, Tevas for short hikes and long walks & Water shoes if you plan to explore reefs and lava rocks.
• Hiking Poles: Particularly helpful on steep descents or for balance on rocky and uneven paths. Many of Oahu’s trails feature challenging terrain, making hiking poles a great addition. Trecking poles: sound silly, but your knees will thank you later! I also prefer the ones that fold up for easier packing!
• Sunscreen & Hat: Hawaii’s sun can be intense. Apply reef-safe sunscreen and wear a wide-brimmed hat to protect yourself from harmful UV rays. You can also save your arms from sunburn with a UV shirt for those long hiking days.
• Rain Gear: Oahu’s weather can change quickly, especially on rainforest hikes. Pack a lightweight rain jacket to stay dry. A lightweight rain jacket or poncho will keep you dry without taking up much space in your bag. Pro Tip: Opt for a compact, packable rain jacket that you can easily throw into your backpack and pull out when needed.
• Snacks: Bring energy-boosting snacks like trail mix, protein bars, and dried fruit to keep your energy up, especially on longer hikes. These are my favorite snacks for the trails and traveling in general: trail mix, fruit bars, protein bars, crackers, meat sticks and mini dried fruit bars.
• Bug Repellent: Mosquitoes are common in jungle and waterfall areas, so bring repellent to keep the bugs away.
• First-Aid Kit: A small kit with bandages, antiseptic wipes, and blister care is essential for any hike.
• Headlamp: If you’re planning on starting a hike early or staying until sunset, bring a headlamp to ensure you have adequate visibility.
•Flushable Wipes & Hand Sanitizer: Public restrooms can be an adventure in themselves—often lacking basic supplies like soap or toilet paper. Save yourself from an unfortunate situation by bringing flushable wipes (unscented) and hand sanitizer. Trust us, you don’t want to be stuck using a leaf in the middle of the jungle, and bring a baggie to keep your trash from the trail to dispose of post hike to ensure trash stays off the trails.
Pro Tip for the Ladies: Unscented wipes are safer to avoid irritation, especially after long beach days.
Safety Tips for Hiking in Oahu
Before setting out on your Oahu hiking adventure, it’s important to know the essentials to ensure your safety and the protection of the island’s natural resources:
1. Respect Trail Closures for Your Safety
Hiking on closed trails is not only dangerous but also puts the lives of rescue personnel at risk. Illegal hikes, such as the infamous Stairway to Heaven (Haiku Stairs), are often closed due to safety concerns like landslides, flash floods, or deteriorating trail conditions. Hiking these trails may seem like a thrilling adventure, but the risk of injury is high. Rescue missions to help stranded or injured hikers on these closed trails divert critical emergency services from local communities, taking away resources needed elsewhere on the island.
Why It’s Important: Ignoring closures puts rescue teams, often comprised of local volunteers and emergency responders, in danger. Rescue efforts on dangerous or illegal trails can strain the local emergency services system, delaying assistance for residents who may need it for other critical situations.
2. Don’t Leave Valuables in Your Car
Break-ins can occur at popular hiking spots, so never leave valuables visible in your vehicle. Store them in the trunk or leave them at your accommodation. Use a waterproof pouch to carry essentials like your phone, keys, and wallet with you during the hike.
3. Check the Weather
Hawaii’s weather can change quickly, with flash floods being a common hazard. Always check the forecast before heading out, especially if you’re hiking in areas prone to heavy rain. Avoid trails with river crossings during or after rain, as water levels can rise quickly.
4. Start Early
The tropical heat can be intense, especially by midday. Start your hike early in the morning to avoid the heat and secure parking, which fills up quickly at popular trails.
5. Respect Hawaiian Culture and Sacred Sites
Many trails pass through culturally significant areas. Always stay on marked paths, respect kapu (sacred) sites, and refrain from disturbing any artifacts or structures you may encounter. Hawaiians hold deep reverence for the land (Aina), so showing respect is essential.
6. Be Prepared for Remote Areas
Many of Oahu’s trails are in remote areas where cell service is spotty. Download maps using AllTrails or similar apps before heading out, and carry a fully charged phone with a portable charger. AllTrails is great because it can be used with no signal and also shows trail reviews, information on finding the trailheads and more indepth info about each hike. Be prepared for no signal by having a paper map or GPS device.
Parking Tips for Oahu Hikers
Parking can be a challenge at many trailheads, especially at popular spots. Here’s how to navigate parking on Oahu’s busiest trails:
1. Arrive Early for Parking: Popular hikes like Diamond Head and Lanikai Pillbox fill up quickly, especially on weekends. Arriving before 8 AM will give you the best chance of finding a spot.
2. Use Designated Parking: Only park in designated areas or official trailhead lots. Parking illegally can result in fines or your car being towed.
3. Be Respectful in Residential Areas: Some trailheads are located in residential neighborhoods. Be mindful of parking restrictions and avoid blocking driveways or fire hydrants.
4. Again: Don’t Leave Valuables in Your Car: Break-ins are not uncommon at popular trailheads and rental cars are targeted.
