Olomana Trail

Olomana

Located near Kailua, this hike can be challenging but you’re guaranteed beautiful ocean and mountain views.  On the way up to the first peak, you’ll walk through different terrains (mud, red dirt, a forest) and there are sections where you won’t want to look down at all.  An adrenaline rush for sure. This is one of my favorite Oahu hikes. There are three peaks on this trail and getting to the third peak can be very challenging.

Pali Puka

Just off the Pali Highway, this short but steep ridge hike has gorgeous views of Oahu.  If you aren’t a fan of narrow ridges and steep cliffs then this hike is not for you.  There are several ropes along the trail that you can hold onto.  It can also get pretty muddy here when it rains.  If you can’t find the puka, (hole) just remember to look down.

Pali Notches

This trail has 360-degree views of Oahu.  The adrenaline kicks in when you are hanging on the side of the mountain as you scale both notches.  This is a super fun hike that can be challenging.  It can also be very windy up here and there isn’t much shade.

Crouching Lion Trail

Crouching Lion

Crouching Lion Trail is located near Kaaawa, Oahu. The Oahu hiking trail has a steep incline and offers remarkable views of the island.

(Difficulty: Know your limits!  Never hike alone and if it’s your first time on a trail, find someone who can guide you.  Bring lots of water, and this is obvious, but don’t hike in the rain.)

Koko Head Stairs

If you’re heading from Honolulu to the East side of the island, you can’t miss the stunning views of Koko Crater. This crater hike is a very steep hike and I would suggest climbing these stairs in the early morning or just before sunset because if you decide to do this hike during the day you won’t catch a break from the sun.

best hikes oahu hawaii - Makaupuu tidepools

Makapu’u Tidepools

To get to Makapu’u Tidepools, it’s a steep climb down rocks to get to the tidepools. There is a blowhole and you should watch out for crashing waves before entering the tidepool. This is a great place for whale watching.

Lanikai Pillbox Hike

Lanikai Pillbox is one of the most popular Oahu hiking trails on the island. It’s an easy and busy hike that offers spectacular views of the ocean and the East side of the island. There are two pillboxes that you can go inside or climb on. This hike doesn’t offer much shade protection. Bring a hat and avoid hiking during the hottest time of the day.

Best Hikes North Shore, Oahu

Ehukai Pillbox Hike

The Ehukai Pillbox trail offers perfect views of the North Shore, and it’s probably one of the trails I’ve been on the most.  The entrance is located at the Sunset Beach Elementary School parking lot. There are two pillboxes with equally stellar views, and this is a great place to unwind and watch the waves.

Kaena Point

I spent a lot of time discovering new tide pools at Kaena Point – where the North Shore meets the West side.  There is a beautiful bird sanctuary here too.  There isn’t much shade on this trail, bring a hat and comfortable shoes because you’ll be walking a lot.  I’ve also seen a lot of whales breach during whale season and Hawaiian monk seals resting on the shoreline.

Best Waterfall Hikes Oahu, Hawaii

Manoa Falls Trail

This is an easy 1.7-mile trail that’s perfect for anyone who wants to enjoy a beautiful hike in nature. When I lived in Hawaii, we used to go beyond the first waterfall to Upper Manoa Falls to swim in a secluded pool. This climb can be very challenging and the last time I visited, the trail to Upper Manoa Falls was closed.

Lulumahu Falls

Lulumahu Falls is an easy and very busy trail. This 1.7-mile hike off the Pali Highway features a beautiful waterfall at the end of the trail. Bring your bathing suit to swim in the pool.

Maunawili Falls

This is a very muddy trail, and it can get slippery at times. Be prepared to walk away with dirty hiking boots. Maunawili Falls is located near Kailua and features a beautiful waterfall. You can also jump off rocks into the pool, or go for a swim.

Ka’au Crater

Difficulty level: This hike is challenging. In some areas, you’ll be scaling waterfalls and stepping on wet rocks that can be slippery. The 7.3-mile loop trail has several tiers to climb. The view from the top of the ridge is spectacular. 

Climbing Mountains: Here’s What to Pack

Hiking Boots

Trails vary from easy to strenuous, and some can get muddy and slippery. Invest in a quality pair of hiking boots. If you’re breaking in a new pair, wear thick socks to avoid getting blisters on your first hike. I’ve used Ahnu and Colombia hiking boots and currently have Merrell hiking shoes. 

Adventure Gear

I prefer to hike in long yoga pants. It also helps protect my legs from any potential bug bites, sunburns, or scratches from the trail. I am currently obsessed with dk active, an ethical activewear brand. I recently partnered with dk active and love their sustainably made stylish crops, tanks, pants, and hoodies. Use coupon: ALEXC20 to get $20 off anything full price. 

Outerwear

I always like to bring a jacket on hikes, because you never know when you might get cold on a trail. Whether you bring a hoodie or rain jacket, it’s always a smart idea to be prepared. I always wear a hat for sun protection, but during the cooler months, a beanie is a great accessory to bring to keep your head warm. Rip Curl has lots of cute and affordable options. 

Swimwear

If you’re planning on going on a waterfall hike, or doing any swimming on your outdoor adventure, don’t leave home without a bathing suit. Whether you want a sustainable bikini or you’re searching for the perfect fit, these are some of my favorite brands: Vitamin ALSPACEdk active. 

Backpack

If you’re planning on going on a long trail, you’ll want to bring something to carry some snacks, water, and essentials like sunscreen. I prefer to bring a small backpack, so I can bring everything I need and keep my hands free. 

Water Bottle

Carry all the water you need in a reusable water bottle or CamelBak. Biome has plenty of stainless steel options.
